Technical Memo is part of the Remedial Investigation/FeasibilityStudy (KE/FS) of the Eau Claire Municipal Vfell Field at Eau Claire,Wisconsin. The Eau Claire Municipal Well Field is located along theQiippewa River, west and southwest of the county airport, in northernEau Claire, Wisconsin (Figure 1-1). The water table aquifer providingwater to the well field is contaminated with low levels of volatileorganic conpounds (VDCs), and trace or slightly greater quantities ofVDCs have been detected in water samples from all of the Eau Clairemunicipal wells. As part of U.S. EPA's remedial investigation (31) ofthe groundwater contamination, a Fhase U field program was initiatedin June 1987.1.1 OBJECTIVE OF HRSE H FIELD EKOGRAMThe Phase I investigation identified several areas where additionaldata and information were required, primarily to define the extent ofcontamination and locate the potential source or sources of thecontamination. The objective of the Hiase II field program was tocollect this additional data which was needed to complete the remedialinvestigation (RI) and to execute the feasibility study (FS).The specific data needed to define the contamination extent included:

o Groundwater quality data upgradient of the wellfield-Hillman contamination plume along the axis of theburied valley to define the extent of the plume;

o Groundwater quality data within the industrial parkcontamination plume along the axis of the buried bedrockvalley to define the distribution of contaminants within theplume;

o Groundwater quality data within and peripheral to the wellfield-Hillman contamination plume to confirm the existingdata on contaminant distributions and define the extent onthe plume;

o Groundwater quality data within and peripheral to theindustrial park contamination plume to confirm the existingdata on contaminant distributions and define the extent ofcontamination; _

o Water level data within the Eau Claire PI study area.ine specific data needed for source examination included:

o Groundwater quality data in the NPI well field to assess apotential source of contaminants in the industrial parkcontamination plume;

FIGURE 1-1 SITE MAP OF EAU CLAIRE, WISCONSIN 1-2

o Soil chemistry data from potential source areas to determinewhether they are contaminant sources and to characterize thenature and concentration of any sources;

o Groundwater quality data from the uppermost part of theoutwash aquifer of potential source areas to show, ifpresent, a linkage between soil contamination andgroundwater contamination.

Specific data needed for quality assurance included:o Groundwater quality data from selected wells sampled withdifferent equipment to evaluate the effect, if any, of

sampling method on reported contaminant concentrations.1-2 SOOPE OF W3RKOne field prixjidin developed to obtain the data required for completionof the PI and execution of the FS consists of three parts. The firstpart was a soil gas survey and soil surface soil sampling to identifypotential sources of contamination. The second part was a program ofsoil borings and source well installations to further characterize thepotential sources. The third part was installation of plumeidentification wells, collection of groundwater samples frctnmonitoring wells, and collection of water level measurements tofurther define and verify the extent of the contamination in thegroundwater. This Technical Memo is divided into six major sections,including this Introduction (Section 1). Section 2 describes the soilgas survey and the interpretation of its findings. Section 3describes the soil sampling and a summary of their volatile organicanalysis results. Section 4 describes the soil borings and the sourcemonitor well installation. Section 5 details the installation of theplume identification wells. Section 6 describes the groundwatersampling and water level measurements.

SECITCN 2SOIL GAS SURVEY

2.1 INTRODUCnCMThe soil gas survey began on 28 June 1987 and was completed on 16 July1987. The survey concentrated on properties within the industrialpark and the municipal airport at Eau Claire, Wisconsin. In total, 71soil probes were installed and the soil gas from them analyzed forselected volatile organic contaminants. The probes were subsequentlyextracted for decontamination and storage.2.1.1 Probe ConstructionThe soil gas probes consist of four metal parts. The four parts arethe probe shaft, the drive tip, the roller pin, and the drive cap.The probe shafts were constructed with thick-wall (.10-inch)galvanized pipe, with an inner diameter of .50 inches. The shaftswere threaded at one end and were six feet in length. The bottom 12inches of the shafts were slotted with equally spaced .10-inch slots.The nonthreaded end of the probes were bevelled with a one inch taper.One inch from the drive tip bottom, a .30-inch diameter hole wasdrilled through the probe to fit the roller pin. The drive tips were4.5 inches long and .60 in diameter, tapering to a .10-inch point.The tips were hanlpnpfl steel and also drilled with a .30-inch diameterhole. A compression roller-pin was inserted in the drive tip throughthe .30-inch hole to hold the tip to the shaft. The threaded end ofthe shaft was fitted with a steel drive cap.2.1 .2 Probe DecontaminationThe probes were decontaminated at a car wash by scrubbing themthoroughly with Alconox and water using a stainless steel wire brush.The probes were then pressure washed using hot water from the carwash, and thoroughly rinsed with distilled water and allowed to airdry. The probes were stored in Visqueen until installation.2.1 .3 Probe Insfr-anation and ExtractionIn many of the areas of the soil gas survey, the ground surface wasconpacted by large machinery or covered with blacktop or asphalt. Inthese cases, a rotodrill hammer, rented from U-Haul Rentals, was usedto drill a 3/4 inch diameter hole into the ground about 15 inchesdeep. The soil gas probes were then advanced into this hole using afence post "slam-bar11 drive hammer. In areas where the soil was notcompacted, the "slam-bar" drive hammer alone was used. The probeswere advanced approximately 4.5 feet into the ground. Afterinstallation, the threaded drive cap was sealed using tape andchain-of-custody seals. After all readings had been taken, the probeswere extracted by loosening them with a rocking motion, then twistingthem out using a large pipe wrench.

2.1 .4 ftnalyHcal InstrumentationTwo instruments were used for analyzing the soil gas in the probes:the Foxboro Miran IB portable ambient air analyzer and the HNuportable phcrtoionizatian analyzer. The HNu was used to analyze fortotal hydrocarbons, while the Miran IB was used to analyze forspecific contaminants.2.1 .4.1 Miran IBThe Miran IB is a micrcprocessor-controlled instrument that can detectand quantitatively measure organic vapors In ambient air inconcentrations from a few ppb to the percentage range. The instrumentuses a nichrome wire source to provide infrared radiation, filtered tospecific wavelengths. The sample is drawn into a gas cell by anintegral air pump at a rate of 25 to 30 liters per minute. The sampleabsorbs infrared energy from the beam. The amount of absorption,measured by the detector, is directly related to the concentration ofthe sample by Beer's law:

A - a x b x cWhere A is absorbance, a is the absorbtivity constant, b is thepathlength, and c is the concentration. The instruments electronicsdisplays the concentration as a digital readout. The Miran IBincorporates a curve correction term to correct for any deviationsfrom Beer's law.The Miran IB was used to analyze for three compounds in the soil gassurvey. These compounds and the Miran IB manufacturer's reporteddetection limits are listed below:

1,1-dichloroethane - 0.4 ppntrichloroethene - 0.2 ppnperchloroethene - 0.4 ppn

These three compounds were selected for the soil gas survey becausethey were among those found contaminating the municipal well field..The other contaminating compounds are not in the preprogrammedcompound library of the Miran IB and are not specifically quantifiableby that instrument without additional programming.2. 1 .4 .2 HNuThe HNu is a portable trace gas analyzer that employs the principle ofphotoionization for detection and measurement -of a wide variety oforganic vapors. Ifcotoionization is initiated by the absorption of aphoton of ultraviolet radiation energetic enough to ionize a moleculeand produce an instrument response, only if the ionization potential(IP) is equal to or slightly less than the ionizing energy supplied bythe instrument's UV lamp (9.5 eV, 10.2 eV, 11.7 eV). As thecontaminants of interest in this survey (chlorinated hydrocarbons)have a high IP, the 11.7 eV lamp was employed to ensure a wide rangeof detectable species.

2.1 .5 Soil Gas Survey Analytical ProceduresThe installation of the probes took place on 29 Jane and 30 June andduriiig the week of 6 July 1987. After installation of the probes inthe survey area, the probes were allowed to equilibrate for 24 hoursor more. Die soil gas was analyzed by the HNu during the week of 6July 1987 and by the Miran IB and the HNu during the week of 13 July1987.Analysis of the soil gas in the soil probe required the probe beattached directly to the analytical instrument. Ihe chain-of -custodyseals were broken and the steel drive cap at the threaded end of theshaft was replaced with a brass .20 inch hose fitting. Tygon tubingwas then used to connect the probe and the analytical instrument. TheMiran IB has a built-in air pump and can evacuate 60 liters of air perminute. An intermediary pump is not required. The pumping mechanismof the HNu probe was also deemed sufficient for evacuation of the gasin the soil probe. After the analytical instrument was attached to aprobe and the analysis of the soil gas initiated, measurements ofcontaminant concentration were recorded every 30 seconds until thesoil gas concentrations stabilized. Stabilization usually occurredwithin three to five minutes. After measurements were made, thethreaded drive cap of the probe was refitted and resealed until thenext contaminant was measured. Because the period of time requiredfor calibration for a specific contaminant, the probes in a givensurvey area were all measured for one contaminant, before proceedingon to the next contaminant compound.2. 1 .6 fri»i-j*y Control Measures2.1.6.1 Miran IBThe Miran IB analyzer contains a library of calibration data for over100 standard gases and vapors. The library consists of the following:name of compound, linear and curve correction terms (constants used inthe equation for converting absorbance to concentration) , alarm limit,wave length, pathlength and air. Due to the pre-set factorycalibrations, field calibration is limited to zeroing the instrumentand identifying background measurements.The Miran IB was zeroed in the field using chemical free compressedair obtained from PADI-certified Blue Waters Divers, Inc. in EauClaire, Wisconsin. A plastic bag was inflated with the chemical freeair, and placed over the hose of the Miran IB. The instrument thenpumped approximately 60 liters (2 minutes) of air into the detector todetermine a zero reading relative to the factory calibration. Duringthis period, the plastic bag was constantly replenished with chemicalfree air. Following the automated zeroing procedure, the instrumentintroduced an ambient air sample. The ambient sample volume extractedwas approximately 60 liters (2 minutes) , during which the instrumentintegrated and updated each reading every two seconds. Attempts tocross-check the Miran IB's calibration with simulated benzenecalibration gas were unsuccessful. The simulated benzene calibrationgas is designed to calibrate photoionization detector instruments

(such as the HNu). The Hiran IB has an infrared detector, and theinfrared absorptions of the simulated benzene gas and benzene are notthe same (conversation with Foxboro, 8 July).Before soil gas measurements, an unwind background sample wasobtained. If possible, the background sample was taken off theproperty to be surveyed. The soil gas survey was then conducted forthe calibrated compound. This procedure was followed for eachcompound analyzed.Duplicate analyses were completed for each compound at each surveyarea. The soil probe chosen for duplicate analysis was analyzed atthe beginning and end of a survey of a given area. Returning to theselected soil gas probe for re-analysis (duplicate sample), after allother probes had been surveyed, gave it an opportunity to restabilize.2. 1 .6 .2 HNuThe HNu was calibrated before and after each day's field screeningwith simulated benzene calibration gas (65 ppm) in accordance with theField Manual for the Operation. Calibration and Troubleshooting of theHNu Riotoionizer. prepared by the U.S. EPA Region V TAT (April 1985).Upwind background samples were taken before sampling a survey area.Each soil gas probe was analyzed at least twice during the HNu survey.2.1 .6 .3 Field ConditionsBecause of the sensitivity of the HNu and Hiran IB to humidity theprobes were surveyed on sunny, dry days. The survey was interruptedthe weekend of 11 and 12 July because of continuous rain in the EauClaire area.2.2 SOIL GAS EBOBE LOCATIONSIn January 1987, field investigations were undertaken to identifypossible source (s) of chloroethene and chlorcethane contamination tothe municipal well field. Hydrogeologic data gathered in Phase I ofthe RI and previous source investigations conducted by the WisconsinDepartment of Natural Resources (WENR) formed the basis foridentification of possible sources. Hydrogeologic data indicated thatthe outwash-filled bedrock valley, trending toward the municipal wellfield from the east, was the most likely area within which contaminantloading could inpact the well field. The WENR studies identified 22facilities within Eau Claire that potentially used chlorinatedethenes and ethanes. The locations of the facilities identified bythe WCNR were cross-checked with the position .of the bedrock valleyand those facilities situated along or near the valley were targetedfor further evaluation.The U.S. EPA Remedial Project Jtonager (RSM) and REM H personneltraveled to Eau Claire to conduct inspections of commercial facilitieswithin the target area. The inspection team interviewed owners oroperators and toured the facilities to make visual observations. Fromthese investigations, four facilities were identified warranting

further study (Figure 2-1). The four potential sources included MaxRiillips and Sons, Rioenix Steel Corp., Gibson Aviation, and the FireTraining Area, located at the Eau Claire Municipal Airport. It wasdecided to screen the soils of each of these areas using soil gasmethodology. In addition, soil probes were to be placed at a privateresidence, the Hlllman property, located northeast of the well field.Riase I RI data indicate higher concentrations of VDCs in groundwatarnear the Hillman property than all other wells.2.2. 1 pillman PiuuertySeven soil probes were placed in and near the Hillman property on June30. Iheir locations are shown in Figure 2-2. Two probes (SG-49, 50)were placed south of the house in the area of the private septicfield. One probe was placed to the east of the house near thedriveway (SO52) to monitor the areas of property cultivated bygardening. Three probes were placed near sheds (SG-51, 53, 54) whichcontained machinery. Much of the machinery was in disrepair and hadnot been used in years. The seventh probe was placed on the airportroad as an upgradient background probe for the Hillman property.2 .2 .2 Fire Protection Training PitA total of 13 probes were installed at the Fire Protection TrainingPit (FPTP) on 30 June 1987. The probe locations are showndiagraramatically in Figure 2-3. Four probes were placed within thepit (SOI, 5, 7, 8). Four other probes were placed along the edge ofthe FPTP (SO2, 4, 9, 12). The last four probes were placed outsidethe edge of the pit (SG-3, 6, 10, 11), Placing the probes in thispattern would allow monitoring of contamination (if any) as it spreadaway from the pit. Probe SG-13 was placed 150 feet south of the pitto serve as a background probe.A single probe (SG-48) was placed in a deep swale-to the east ofGibson Aviation and southwest of the Fire Protection Training Pit.This area appeared to be where soil was removed to help provide fillfor airport construction.2 .2 .3 Gibson AviationNine prcbes were installed at Gibson Aviation on 7 and 8 July. Thelocation of these prcbes are shown in Figure 2-4. Soil probes SG-40,41, and 44 were placed around the hanger area where degreasingsolvents are used. Prttoe SO47 was placed in a grassy area betweentwo buried tanks in front of the quonset hut and two turied tanksunder the small plane parking area. The grass had oval depressions,about 55-gallon drum size, at this location. The vegetation was brownand stunted in these depressions. Soil probes SG-43, 45 and 46 wereplaced near the shed storing solvents and near where aviation fueltrucks for Gibson Aviation are normally parked. Probe SO39 wasinstalled near the septic field, and soil probe SG-42 was placed toserve as a background probe for this area.

2 .2 .4 Rioenix Steel Corp.Sixteen probes were placed at Hioenix Steel Corporation on 8 July1987. Bie probes were installed after using a rotohammer to drillthrough the first 18 inches of compacted soil ard/or asphalt. ProbesSG-56, 57, 58, 59, 60 were installed in the asphalt near the southwestcorner of the main plant where drums of waste and sludge were stored.Soil probes SG-61, 62, 63 were placed to the south of the paintbuilding. IJiey were placed to detect any contamination from the paintsludges stored in drums on a concrete pad next to the south side ofthe building. Probe SG-64 was placed beside another drum storage areato south of the paint building. Probes SO65, 66, 67 were installedaround the buried paint sludge pit. Probes SG-70 and 71 wereinstalled downslope from the Bridge Fabrication shop and maintenanceshop. Probes SG-68 and 69 were placed in lower areas near fencesdividing Max Hiillips & Son and Ehoenix Steel, where runoff from bothproperties collect. The locations are shown in Figure 2-5.2.2 .5 Max Riillips & SonA total of 25 probes were installed at Max Hiillips & Son on 7 July1987 (Figure 2-6). Soil probes SG-15, 16, 17, and 18 were placed inthe northwest corner of Max Riillips & Son where the railroad entersthe property and large trucks are parked. Soil probes SO14, 19, 20and 21 were placed at corners of the maintenance garage anddowngradient from its operations. Solvent use had been suspected inthat area. Probes SG-22, 23, 24, 25, 26, and 27 were placed tosurround the large drum storage area on the north-central part of theproperty. Probe SG-33 was placed in the stained soil near largecrushed storage tanks. Probe SG-28 was placed near a drum storagearea in the west-central part of the property. Pcobes SG-29, and 30were positioned in the north and south corners of a building housing ametal crusher. A large amount of hydraulic fluid was pooled andsoaking the soil at this location. Probes SG-31, 32 and 35 wereplaced in the yard used for storing cut or crushed metal. ProbesSG-34, 36, and 37 were placed near the building housing a large metalcutter and its associated sorter. Probe SG-38 was placed on WhiteRoad to serve as a background probe for both the Max Riillips & Sonand Hioenix Steel properties.

2.3. 1 Hillman PropertyThe soil gas in the probes at the Hilknan property were analyzed forgeneral hydrocarbons on 7 July and 8 July and'13 July. The probeswere analyzed for 1,1-dichloroethane (DGA), trichloroethene (TCE), andperchloroethene (PCE) on 13 July. Table 2-1 summarizes the results ofthe survey.The total hydrocarbon readings on the HilLnan property were erraticand inconsistent. Several high readings were measured on 7 July atprobes SG-52, 53, 54 and 55; but were not confirmed the following day,8 July. A third round of measuring on 13 July did not yieldconsistent results either. An explanation for this very erratic

behavior may be the effects of humidity. Mr. Hillman has a very largegarden and a lush green lawn which he keeps well watered. If the soilhas a lot of moisture, the soil gas will be very humid. The HNUphotoionization detector is very sensitive to humidity and may not beable to measure the total hydrocarbons accurately under theseconditions.Measurements of perchloroethene in the soil gas were consistently lowin all probes in the Hillman property. Essentially, backgroundreadings in all cases. The same is true of trichloroethene, exceptfor probe SG-49. It stabilized at 4.9 ppm TC£ after four minutes ofmeasurements. The soil gas at this probe also contained the highestconcentrations of DCA (4.9 pgni). She concentrations of DCA inthe soil gas at the other probe locations were closer to thebackground measurement of 2.7 ppn.2 .3 .2 Fire Protection Training PitThe soil gas in probes installed at the Fire Protection Training Pitwere analyzed for general hydrocarbons on 8 July and 16 July. Thesoil gas was analyzed for trichloroethene, perchloroethene, and1,1-dichloroethane on 16 July 1987. Table 2-2 summarized the resultsof the survey. Because of the close proximity of the probes, it wasdecided measurements of the middle ring of probes were unnecessary.Hydrocarbon levels measured at the Fire Protection Training Pit wereat or near background levels for all probes measured, except SOI. Atthat probe, a reading of 50 ppn was detected. The reading was veryerratic and inconsistent.Trichloroethene measured in the soil gas ranged from 0.5 to 1.9 ppm.Background levels were measured at -0.1 to 0.5 ppm. Probe SG-1 hadthe highest level of measured trichloroethene. Perchloroethene wasdetected at background levels only from -0.9 to -0.4 ppn.Perchloroethene at the background station Treasured -0.8 ppm.The background reading for the 1,1-dicJiloroethane at the FireProtection Training Pit measured initially at 2.2 ppm, but as theinstrument was used to measure the soil gas in the probes, it driftedup to 8.9 ppm. Measurements mndft took the drift into account. TheDCA detected in the soil gas ranged from 3.7 to 6.7 ppn. Soil gasprobes SG-1 and SG-5 contained 6.0 and 6.7 ppm, respectively.2 .3 .3 Gibson AviationThe soil gas in the probes at Gibson Aviation property were analyzedfor general hydrocarbons on 8 July, 14 July, and 15 July. The probeswere used to analyze for DCA and TCE on 14 July. The survey wascompleted at Gibson Aviation on 15 July when the probes were used toanalyze for PCS. Table 2-3 summarizes the results of the survey.Total hydrocarbons, as measured by the HNu, were at zero or backgroundlevels for probes SG-39, 40, 41, and 42. The probes near the solventshed registered several values above background. Most consistent wasSG-43 where readings 5, 3-5, and 0-20 ppm were detected. At SG-44 one

measurement of 15 ppn was made en 14 July 1987. At SG-45, ameasurement of 27 ppn was also made, on 14 July 1987. At probe SG-46,a measurement of 120-500 ppn was detected on 15 July 1987. Althougherratic, these probes are grouped together in one area of the propertywhere solvents are used and aviation fuel pumped. The numbers are,therefore, not unreasonable. Itydrocarbons at a concentration of 0-52ppn were detected at SG-47. Ihis is an area between severalunderground aviation fuel tanks and fuel odor is noticeable in thisarea.Measurements for trichloroethene were consistently 1.0 ppn (0.6-1.2ppm) above background (-0.2) In the soil gas measured at GibsonAviation. When analyzed for perchloroethene, the soil gas was about0.75 jpn (0.8-1.5 ppn) above background (0.5 ppn). Therefore, neithercontaminant was detected in a significant concentration. Theconcentrations of 1,1-dichloroethane (DCA) detected did appear tobe significant. Every probe, except SG-40 (1.9 ppn), containedconcentrations of DCA (4.1-9.9 ppn), three ttmpq background of 1.3fpn. Probes SG-47 (9.9) , SG-43 (7.1) , and SG-41 (6.5) had the highestvalues. Soil gas probe SG-47 is near the underground fuel tanks andprobe SG-43 is downslope of the solvent shed.2 .3 .4 Rioenix Steel Oorp.The soil gas In the probes at Rioenix Steel Corp. were analyzed forgeneral hydrocarbons on 14 July. The probes were used to analyze forDCA, TCE, and PCS on 14 July. Table 2-4 summarizes the results of thesurvey.The survey of general hydrocarbons was generally negative. Allmeasurements were at background or just above. Exceptions were probeSG-56 (7 ppn), probe SG-57 (28 ppn) and probe SG-59 (6 ppm). All ofthese probes are in the area near the main plant where drummed wastewas stored.Measurements of perchloroethene varied from 0.3 ppn to 1.9 ppn. Themeasurement for background was 0.3 ppn. As measurements were takenthroughout the property, the background reading gradually drifted to1.5 ppn. Therefore, the PC£ concentrations were not significantlevels. Trichloroethene in the soil gas was measured in levels from0.4 to 2.0 ppn. The background reading for trichloroethene remainedbetween 0 to -0.4 pp&. The highest value of 2.0 ppa was found inprobe SG-57, which had the highest hydrocarbon value as well.Measurements of 1,1-dichloroethane varied firon 0.5 to 9.8 ppnthroughout the property. A background level of 2.2 ppm was measuredin ambient air. Tne areas around the main plant and downslope fromthe bridge plant contained the highest concentrations. The fiveprobes near the main plant contained DCA concentrations of 3.9-9.8ppm. Near the bridge plant, values were measured at 3.5-6.4 ppn.Soil gas probe SG-63 contained 4.5 ppa DCA and soil gas probeSG-64 contained 4.2 ppn DCA. Both of these probes are south ofthe paint building.

2 .3 .5 Max Riillips & SonThe soil gas in the probes installed at Max Hiillips & Son wasmeasured for general petroleum hydrocarbons on 8 July and 15 July.The probes were used to analyze for trichloroethene andperchloroethene on 15 July. Perchloroethene and 1,1-dichloroethanewas analyzed in the soil gas on 16 July. Table 2-5 summarizes theresults of the survey.Jtydrocarbon measurements at Max Riillips & Son were near backgroundlevels except at a few locations. Probe SG-14 near the Max Jhillips &Son maintenance garage measured values 0-15 ppn on 8 July. In thesteel scrap yard, measurements of 100-120 ppn were detected at probeSG-32 on 15 July. Measurements of 2-4 ppm were detected around thestored 55-gallon drums, but these were inconsistent. A measurement of60 ppm was detected in the stained soils where metal storage tanks arecrushed. Definite fuel odor was detected as well.Measurements of perchloroethene ranged from -0.2 to 0.9 ppm in thesoil gas. The background ambient air measured 0.0 ppm. Therefore,there was no significant perchloroethene concentrations measured atMax Riillips & Son. Trichloroethene was detected in concentrationsfrom 0.5 to 4.4 ppn. The highest values (3.1-4.4 ppm) were detectedin the stored drum and large storage tank areas. These areas also hadhigh background readings of ambient air (2.5-3.0 ppm), so thesignificance of these measurements is minimal. Measurements of 2.4,3.6, and 3.3 ppm were detected in probes SG-14, 20, and 21,respectively. These values may be significant.Concentrations of 1.1 to 9.5 ppn DCA were detected in the soil gasin probes at Max Riillipe & Son. The background ambient air levelsremained constant at 1.0 to 1.5 ppn throughout the property. Severalareas were high In value. The areas which drain the maintenancegarage had values of 8.5, 8.7, and 9.5 ppm (SG-14, 20, 21) . Theprobes around drums and storage tanks in the back of the property(SG22-28, 33) had values ranging from 3.4 to 5.0 ppn. The two probesin back of the metal crusher (SG-29, 30) had values of 7.6 and 9.4ppn. In the scrap metal yard, to the southeast of the crusher, valuesof 6 .5 , 6.1, 4.9, 3.8, 4 .6 , and 3.8 were detected (SG-31, 32, 34, 35,36, 37) . In the areas of the crusher, metal scrap yard, and cutterpools of hydraulic fluid and oil have stained much of the grounds.2.4 DISCUSSION OF SOIL GAS RESULTSThe soil gas survey found several indications of possiblecontamination sources in the municipal airfield and industrial parkarea. These source areas coincided with visually identified suspectareas. These areas were not strongly contaminated and cannot beconclusively identified as having contributed to the municipal wellfield contamination. 'The soil gas survey indicated the Hillman property was probably not acontamination source. The HNu survey for general hydrocarbons gavehigh readings at a number of probes; but, the readings could not be

confirmed by repetition. Hie survey for perchloroethene,trichloroethene and 1,1-dichloroethane, gave primarily backgroundreadings, except for probe SG-49. Probe SG-49 was placed in thegrassy yard over the septic field for the Hilljnan's property. the 4.9ppm 1,1-dichloroethane and 4.9 ppm trichloroethane detected in thesoil gas at this probe are possibly from the septic field. If so,their presence is due to natural decomposition from the septic fieldor from some household waste which was flushed down the drain. Ineither case, it seems unlikely the septic field is the source ofmunicipal well field contamination.The Fire Protection Training Area does not appear to be a source ofthe municipal well field contamination. The soil gas in the probesdid not contain hydrocarbons, trichloroethene, and perchloroethene insignificant concentrations. The levels of 1,1-dichloroethaneconcentrations are suspect because of instrument drift at this time.The soil gas survey found three areas of possible source contaminationat Gibson Aviation. The first is by the solvent shed to the southwestof the main hanger (Figure 2-4). The detection of hydrocarbons in thesoil gas by the HNu, the presence of concentrations of 5.0-7.1 ppm1,1-dichloroethane in the soil gas are indications that somecontamination of the soil by operations at Gibson has occurred.Aviation fuel trucks regularly park beside the solvent shed. If thetrucks leaked at any time, they could contaminate the soil withhydrocarbons. The second area is between the underground fuel tanks.The soil is discolored at this location, and an aviation fuel odor isnoticeable. The HNu detected hydrocarbons in the 0-50 and DCA wasdetected at concentration of 9.9 ppm. It was determined in the fieldthat aviation fuels or gasoline may be a source of 1,1-dichloroethane.When the instrument was used to test the vapors emanating from anautomotive gas tank, readings of 32 ppm, DCA were measured. Analternative explanation may be that an ingredient of gasoline isdetected at the same wavelength as DCA by the Miran IB. A thirdsource may be the former septic field for Gibson Aviation, extendsfrom the buildings under the parking lot. Solvents and degreasersused in the hanger area were flushed into the septic field throughfloor tiles. The only indications of septic field contamination wereDCA detected in probes SG-39 (4 .8 ppm), SG-42 (4.1 ppm), and SG-41(6 .5 ppm). According to Mr. Gibson, the septic system of GibsonAviation is now hooked into the municipal sewer that serves theairport.At Phoenix Steel Corp., the soil gas survey detected hydrocarbons(6-28 ppm) and 1,1-dichloroethane (3.9-9.8 ppm) outside the southwestcorner of the main plant where drummed waste was stored. This area isa possible contamination source. The probes around the paint buildingwere contamination-free, except for DCA detected in probe SG-61(3 .5 ppm), SG-63 (4 .5 ppm), and SG-64 (4 .2 Ppm). But, because of thelarge volume of paints and solvents used, it still must be considereda possible source. The probes around the pit where paint sludges wereburied did not detect any significant contaminant concentrations, butit is still a possible source, as the paint sludges are highlyvolatile. The probes in the low areas southwest of the bridge plantcontained DCA contamination in levels of 3.5-6.4 ppm.

2-21

The soil gas survey pinpointed several areas of the Max Riillip & Sonproperty as possible sources for the nunicipal well fieldcontamination. The area southwest of the maintenance garage is a lowarea where runoff collects and oil residuals stain the ground. Probesin this area detected DCA in concentrations of 8.5-9.5 ppnu Inaddition, concentrations of 2.4-3.6 TCE were detected. Probes aroundthe drum storage area contained DCA in concentrations from 3.4-5.0ppn. The concentrations of TCE in these probes were 3.1-4.2 ppn.This suggests some solvents drained from the drums when they werestored. The practice of Max Riillips & Son of crushing large storagetanks and letting them drain the residuals indicates another possiblesource. The soils are heavily stained in this area and surfacereadings of 60 ppm with the HNu were recorded. The final possiblesource area is the steel storage area between the crusher and largecutter. Pools of hydraulic fluid and oil are found around thebuildings and the soil gas probes indicate values of DCA (SG-30,9.4 ppn) and hydrocarbons (SG-32, 100-120).In summary, possible contaminant sources were identified at GibsonAviation, Ricenix Steel, and Max Riillips & son. They are itemized asfollows:Possible sources at Gibeon Aviation include:

o Solvent shed to the southwest of main hanger;o Area between the underground fuel tank; and,o The former septic field.

Possible sources at Phoenix Steel include:o Haste storage area at southwest corner of main plant;o Paint sludge storage areas south of paint building; and,o The exhumed paint sludge pit.

Possible sources at Max Riillips & Son include:o Drainage area southwest of maintenance garage;o Drum storage area;o Crushed storage tank area; and,o The steel storage area around the compactor and metal

cutter.Individually, none of these possible sources would appear to be thesole contaminant source of the solvents found in the municipal wellfield, but collectively, they may be significant contributors.

SECTICN 3SURFACE SOIL SAMPLING

3.1 INTRODUCTIONAfter the soil gas survey, a program of surface soil sampling wasinitiated. The intent of the surface soil sampling was to confirmareas of contamination found ty the soil gas survey and to pinpointlocations of soil borings that were to be turned into sourcemonitoring wells. After extensive consultation with the U.S. EPArepresentative on site, 15 samples were collected on 24 July 1987 andthree samples collected on 29 July 1987.3.1.1 Sampling ProcedureSoil samples were taken from the top 6 to 12 inches of soil in theselected locations. A shovel was used to dig a shallow trench withvertical walls. A disposable sterile scoop was used to scrape soilaway from the trench wall to reveal undisturbed soils. A disposablesterile scoop was used to transfer the soil to a 40 ml glass vial witha Teflon top. The vial was labeled and sealed with plastic tape. Thesamples were stored in an iced cooler until transported to PACELaboratories, Inc. for analysis.3 . 1 .2 Analytical laboratoryThe soil samples were analyzed by PACE laboratories, Inc. ofHinneapolis, Minnesota. The samples were analyzed in accordance withU.S. EPA Method 5030 (sample preparation and extraction) and U.S. EPAAnalytical Method 601. The samples were analyzed for eight specificvolatile organic conpounds on a quick turn-around (24 hour) basisinstead of CLP (U.S. EPA Contract laboratory Program) criteria. Theeight compounds and the requested detection limits are listed below:

3. 1 .3 Quality Control MeasuresThe surface samples were placed in clean glassware from I Qiem.Disposable sterile scoops were used to transfer the soil to theglassware. A duplicate sample (SS-16DUP) was taken from the FireProtection Training Pit and a blank (SS-17 BLANK) of diatomaeous earthwas included. Samples SS-1 through SS-15 (sampled 24 July) were

3-1

transported in an iced cooler to PACE laboratories, Inc. by car by aU.S. EPA representative. Qiain-of -Custody forms were completed atPACE laboratories, Inc. by the EPA representative and custodytransferred to the lab. The second group of samples were shipped inan iced cooler to PACE Laboratory by Federal Express.3.2 SURFACE SOIL SAMPLE LOCATIONSThe locations of the surface soils are shown on Figures 2-2 to 2-6.Table 3-1 lists the soil samples and a brief description of theirlocation. No surface soil samples were taken at Hillman's property asthat location was not considered a probable source.3.2. 1 Fire Protection Training Pit

surface soils were sampled on 29 July 1987 at the center of theFire Protection Training Pit. Ihe first was labeled SS-16, the secondwas a duplicate sample SS-16 DUP. In addition, a blank sample wasprepared of diatomaceous earth and labeled SS-17 BLANK.3 .2 .2 Gibson Aviation

surface soil samples were taken from the Gibson Aviation property.Sample SS-1 was taken between soil gas probes SG-43 and SG-45 directlynorth of shed containing solvents. This location was chosen becauseof the solvents and because the soil gas survey had measuredhydrocarbons in concentrations of 3.5-500 ppm and 1,1-dichloroethane(DCA) in concentrations 5.0-7.1 ppm.A second sample (SS-2) was taken beside probe SG-47. The grass wasindented with curcular impressions like 55-gallon drums. When thesample was taken, a strong petroleum odor was noted. Ihe soil gassurvey had detected 1,1-dichloroethane at 9.9 ppm and hydrocarbons at50 ppm.3 .2 .3 Ehoenix Steel Corp.Four surface soil locations were sampled on 24 July 1987. Two ofthese samples (SS-9 and SS10) were taken in soils surrounding theburied paint sludge pit. Soil sample SS-9 was taken near probe SG-66and soil sample SS-10 was taken near probe SG-67. Soils were,therefore, sampled to the north and to the west of the pit.Sample SS-11 was taken beside the stored drums south of the paintbuilding. These drums were filled with sludge and some had bulgedconsiderably in the sun because of vapor pressure from materialsinside them. "'Surface soil sample SS-12 was taken in the steel storage area to thewest of the main plant. This location was the closest to the cornerof the main plant where wastes were stored in drums. Soil gasesmeasured in this area contained concentrations at 5-10 ppm DCA andup to 28 ppm total hydrocarbons.

3 .2 .4 Max Riillips & SonSeveral surface soil samples were extracted from the area downslope ofthe maintenance garage at Max Fhillips & Son. Soil sample SS-3 wastaken beside probe SG-20 in a drainage swale. Concentrations at7.7-9.5 ppm of DCA and 2.4-3.6 ppm of trichloroethene (TCE) weremeasured in probes in this area. Additional soil samples were takenfrom oil-stained soils near the abandoned crusher (SS-13); from thedrainage swale near probe SG-21 (SS-14); and from the low ponding areanear the fence dividing Max Riillips & Son from Rioenix Steel Corp.properties (SS-15).Three surface samples were extracted from soils on the north, south,and west sides of the drum storage area (SS-4, SS-5 and SS-6).Concentrations of 3.4-5.0 ppn DCA and 3.1-4.2 ppn TCE had beendetected in the soil gas in this area. Several drums were labeledtrichloroethene. Sample SS-5 was taken immediately beside one suchdrum. Sample SS-6 was taken beside several drums labeled HazardousWaste with EPA codes on them.Surface soil sample SS-7 was taken from the stained soils below largecrushed storage tanks. Petroleum hydrocarbons were detected inconcentrations up to 60 ppn on the surface next to the soils at thislocation and concentrations of 3.6 ppm DCA and 4.4 ppm TCEmeasured in the soil gas. One further soil sample (SS-8) was takenbeside drums near probe SG-28. Higher background ratings of DCAwere detected in this area. All 10 surface soil locations at the MaxRiillips & Sons' site were sampled on July 24, 1987.

3.3 RESULTS OF ANALYSISAnalysis of the surface soil samples determined none of them containedthe eight compounds listed in Section 3 . 1 .2 in concentrations at orhigher than the requested detection limits. Therefore, the solvents thatcontaminate the groundwater did not remain in the first 12 inches ofsoil or the solvent contaminatian occurs at other locations. Thecomplete report of PACE laboratories, listing the cornpounds analyzedand detection limits, is included in Appendix B.

SECITCN 4SOIL BORINGS AND SOURCE WELL INSTALLATION

4.1 LOCATION OF SOIL BORINGSThe second part of the field program consisted of source soil boringsand source monitor well installation. The Sampling and Analysis Planstates that the soil boring locations were to be based on visualobservations (such as stained soils), field conditions (topography,access, utilities, site operations, etc.), and the soil gas survey.Surface soil samples were taken with the intent of identifyinglocations with the greatest concentrations of volatile contaminants.The borings were to be placed at these locations.The soil gas survey did not identify any obvious sources. It dididentify possible contributing sources, but the surface soil samplesdid not verify any of these locations. It was, therefore, decided toplace the borings at locations downgradient from possible contributingsources identified by visual observations and the soil gas survey.The locations were also limited by the operations at the industrialpark, especially at Max Riillips & Son and Shoenix Steel Corp. Afterconsultation with the managers at the industrial sites, U.S. EPArepresentatives, and WCKR representatives, satisfactory locations wereselected. The soil borings were completed and the source wellsinstalled from 28 July to 1 August and on 11 and 12 August 1987.4.1 . 1 Fire Protection Training Pit

One soil boring and source monitor well (HW25) was installed at theFire Protection Training Pit (Figure 2-3). Although the soil gassurvey revealed no significant contamination and the soil sample takenfrom the pit showed no solvent contamination, a source well was placeddowngradient from the pit location. It was felt that since the pithad not been used for several years, the surface soil may be clean ofvolatiles, but contaminants may have reached the groundwater at thislocation. A well at this location would also helped define the extentof the well field - Hillman contamiriant plume. This source well wasdrilled and screened 10 feet into medium-grained sandstone bedrockat depths of 55 to 65 feet.4. 1 .2 Gihson AviationOne soil boring and source monitor well (IiW24)^was installed at GibsonAviation. This location was selected to be downgradient from threeareas: the underground fuel tanks, the storage solvent shed, and theformer Gibson Aviation septic field. As described in Sections 2 .3 .2and 2 .4 , the soil gas survey detected contamination from each of theseareas. The location of the well is shown in Figure 2-4 with thesource areas, soil gas probes, and soil sample locations alsoidentified. This well was screened in outwash from 66 to 76 feet.

4. 1 .3 Ricenix Steel Corp.Ciree soil borings and source monitor wells were installed at RioenixSteel Corporation (Figure 2-5). Monitor well EW21 was installed 100feet west of the Main Plant and screened in outwash at depths of 63 to73 feet. The southwest corner of the Main Plant was identified by thesoil gas survey as a source of 1,1-dichloroethane. The placement ofthe well makes it downgradient from the Main Plant. Monitor well PW22was installed at the southwest corner of the paint building andscreened in outwash at depths of 62 to 72 feet. The well wasinstalled at this location to monitor downgradient from the two paintsludge storage areas south of the paint building. The third monitorwell, IW16, was placed directly west of the paint storage pit that hadbeen recently exhumed. It was screened in outwash at depths of 63 to73 feet. As shown in Figure 2-5, the placement of these three wellsenables the entire Fhoenix Steel plant operations area to be monitoredfor groundwater contamination.4. 1 .4 Max Riillips & SonFive soil borings and source monitor wells were installed at MaxFhillips & Son (Figure 2-6). Monitor well EW17 was installed justwest of the drum storage area and screened in outwash at depths of 60to 70 feet. Although the soil gas survey and surface soil samplesrevealed very little, the fact that drums labeled trichloroethene werein the storage area warranted placing a monitor well at this location.In the area where storage tanks were crushed and drained the soilswere obviously stained. Monitor well FW20 was set at this location tocheck the depth of contamination. It was screened in outwash atdepths of 64 to 74 feet. If chemical storage tanks have been crushedand drained at this location, as well as fuel storage tanks, then thislocation may be a major contributing source. Monitor well FW18 wasplaced downgradient of the southern part of the property to monitorthe area containing the steel storage area, the crusher, and the largesteel cutter and sorter. This area had much soil staining byhydraulic oils and fuels. Also, several of the soil probes (asdescribed in Sections 2 .3 .4 and 2 .4 ) contained concentrations of1,1-dichloroethane above background. Monitor well FW18 was screenedin outwash at depths of 62 to 72 feet. A fourth monitor well (BN23)was set downgradient from the maintenance garage and northeast of theabandoned crusher by the railroad. The soil probes in the areadetected concentrations of 1,1-dichloroethane above background and thesoils are very stained by fuels and hydraulic oils. Monitor well FW23was screened in outwash at depths of 60 to 70 feet. The fifth monitorwell at Max Ifcillips & Son was placed in a low drainage-way by thefence just west of the gate connecting Rioenix Steel Corp. and MaxFhillips & Son. The well was placed so it was downslcpe from themaintenance garage of Efcoenix Steel. Soil probes in this area haddetected concentrations of 1,1-dichloroethane above background.Monitor well EW19 was screened in outwash at depths of 60 to 70 feet.

4.2 pPTTT.TMS ECXJTfMENT AND IRXEDURE5The drilling was performed by Exploration Technology, Inc. (ETI) ofMadison, Wisconsin and Wisconsin Test Drilling of Schofield,Wisconsin. BTI used a Offi 75 truck-mounted drill rig and WisconsinTest Drilling used a Central Mine Equipment CME 750 all-terrainvehicle (ATV) drill rig. Both rigs used two man crews with a fifthman used to operate the water truck and perform decontamination. Withone exception, the borings for monitor well installation were advancedusing 4.25-inch I.D. hollow stem augers. Monitor well F5-725 wasdrilled by hollow stem auger through outwash for the first 50 feet,then drilled by air rotary into sandstone to 68 feet.4.3Prior to drilling at each location, the back of the drill rigs, allhand tools, well construction materials (riser pipe and well screen)and equipment were decontaminated. Decontamination consisted of hightemperature steam cleaning using a high pressure steam jenny.

4.4 SOIL BORINGS4.4. 1 Sampling Procedures and Analytical laboratorySamples, with one exception, were taken in the soil borings at depthsof 0 feet, 2.5 feet, 5 feet, 7.5 feet, and 10 feet, and at 10 footintervals thereafter to the water table (usually to 60 feet) . Ihesamples were taken using two-inch and three-inch split spoons. Thelarger split spoon was used when a larger volume of sample wasrequired (such as when taking matrix spike or duplicate samples) .large pebbles prevented the split spoon from obtaining a sample at 5feet and 7.5 feet at IW18. The samples were successfully extracted atslightly lower depths 6 feet and 8.5 feet. The split spoons weredecontaminated by scrubbing them in an Alconcx wash, then thoroughlyrinsing them with deionized water. Ihe samples were transferred toCLP glassware (250 ml glass bottles) using sterilized disposableplastic scoops by a WESTCN geologist. The soils were examined andlogged into field books for future reference.The samples were stored in iced coolers and shipped by Federal Expressto Southwestern Lab of Tulsa, Oklahoma and Century Refining Company ofBrighton, Colorado, under the U.S. EPA's Contract laboratory Program(CLP) . The soil samples were to be analyzed for Routine AnalyticalServices (RAS) volatile organic compounds.4 .4 .2 Qnal ty Assurance -One duplicate sample was taken at every soil boring (one every 10samples) , plus one matrix spike sample was taken per 10 samples. Inaddition, trip blanks were included in each day's shipment of coolers.The duplicate samples, matrix spike samples, and trip blanks wereanalyzed for Routine Analytical Services (RAS) volatile organiccompounds.

4 ,4 . 3 Boring LogsIn general, the soil borings encountered medium to coarse, moderatelysorted quartz Bands interbedded with gravels and pebbles. Beds ofsubrounded to subangular pebbles were occasionally encountered,usually lasting six inches to a foot. In the industrial areas, thesurface soils were often stained with oils and fuels, occasionally todepths of 6 to 12 io^hes under the surface. Gravel occurredthroughout the area. FW25 was drilled into 18 feet of bedrocksandstone. The sandstone was white medium-bedded quartz arenite.Detailed descriptions are in the boring logs found in Appendix C.4.5 SOURCE MDNi'lUK WFTT. INSTALLATIONAll source monitor wells were constructed of stainless steel 2 inchI.D. casing and a 2-inch I.D. stainless steel screen with 0.010-inchcontinuous slots. Hie natural sands were allowed to collapse aroundthe well screens to form a sand pack. High parity silica sands wereused to augment the natural sands, usually to ensure the sand pack wastwo to five feet above the top of the screen.Bentonite pellets (usually two buckets per well) were poured on top ofthe sand pack to make a four-foot bentonite pellet seal. The pelletswere hydrated with about 10 gallons of water and tamped with tremmiepipe. Cement bentonite grout was then pumped by tremmie pipe from thebentonite seal to the surface. A six-inch steel protective casing wasinstalled over each well and anchored with cement. A sloping cementp*H was placed around each well and the protective casing locked witha padlock.All source monitor wells were screened 10 feet, 7 feet in the presentwater table and 3 above it. Table 4-1 lists the well screenintervals. All wells were screened in the sand and gravel outwashexcept FW25, which was screened in 10 feet of sandstone bedrock.Detailed descriptions of the wells are found in the constructionsummaries in Appendix C.4.6 SOURCE MONITOR WELL ULV^'l ORg^TAll newly installed PEM source monitor wells were developed by pumpingwith a positive-displacement pump or by bailing. This insured fullflow between the aquifer and the well screen prior to sampling. Aminimum of 11 well volumes of water was removed from each well duringdevelopment. U.S. EPA REM well FW25 was developed with a bailer sinceit was screened in bedrock, it recover very slowly. Source monitorwell development data are presented in Table 4-2.

SECTION 5FUME IDEWITFICATICN WELLS

5.1 IDCRTION .Riase I sampling results indicated the presence of two VDCcontamination plumes. One, narrow and well defined, occurs northeastof the municipal well field with VDC concentrations exceeding 100 ppbin the center of the plume. The second, more diffuse plume, islocated within the outwash aquifer in the vicinity of the industrialpark with VDC levels ranging from 5 to 10 ppb.The Phase I sampling results did not fully define the first plume(well field-Hillman) in its upgradient extent. To address thisproblem, additional monitor wells were needed along the axis of theburied valley in the vicinity of the airport. Therefore, threemonitor wells were installed during the Riase H field program: IW10,RW11, and IW12 (Figure 5-1).The Phase I sampling results did not define the second plume's(industrial park) contaminant concentrations along the axis of theburied valley. To address this data need, monitor wells RW14 and 5W15were installed during the Phase H field program in the middle of theburied valley. Monitor well RW13 was installed along the southernedge of the buried valley (Figure 5-1).The plume identification wells were installed during the period from20 July to 24 July and 11 and 12 August during Phase H fieldinvestigations. Utility clearances had been completed and locationsstaked the previous weeks by a WESTCN geologist. Field conditions(overhanging utility lines) required that the placement of one of themonitor wells, FW15, be moved from the location identified in thePhase II work plan. The monitor well was moved from the northwestside of Route 53 to the southeast side of Route 53, just southwest ofNational Presto Industries. This relocation was still satisfactoryfor fulfilling the data need of defining the contaminant concentrationof the industrial park plume along the axis of the buried valley.5.2 npTTT.TMR EQUIPMENT ANDThe drilling was performed by Exploration Technology, Inc. of Madison,Wisconsin and Wisconsin Test Drilling of Schofield, Wisconsin. ETTused a CME 75 truck-mounted drill rig and Wisconsin Test Drilling useda Central Mine Equipment CME 750 ATV drill rig. Both rigs used twoman crews, with a fifth man used to operate the water truck andperform decontamination. With one exception, the borings for monitorwell installation were advanced using 4.25-inch I.D. hollow stemaugers. During the initial boring for RW13 the hollow stem augersbecame lodged at a depth of 95 feet after equipment failure had forcedthe drillers to leave them in the boring overnight. A longer drillrig (Olson Brothers) was brought to the site and 10-inch casingdrilled around the augers which freed the augers. The hole was then

and grouted to surface. The location for RW13 was moved 25feet upgradient (south) to prevent grout contamination from theinitial boring. The second boring for KW13 was drilled by hollow stemauger for the first 60 feet throucpi outwash, then drilled by airrotary into bedrock to 75 feet.5.3Prior to the drilling at each location, the back of the drill rigs,all hand tools, well construction materials (riser pipe and wellscreen) and equipment was decontaminated. Decontamination consistedof high temperature steam cleaning using a high-pressure steam jenny.5.4 1CNITORAll plume identification wells were constructed of PVC 2-inch I.D.casing and 2-inch I.D. PVC screen with 0.010-inch continuous slots.The natural sands were allowed to collapse around the well screens toform a sand pack. High purity silica sands were used to augment thenatural sands, usually to ensure the sand pack was two to five feetabove the top of the screen. Bentonite pellets (usually two bucketsper well) were poured on top of the sand pack to make a four footbentonite pellet seal. Die pellets were hydrated with about 10gallons of water and tamped with tremmie pipe. Cement bentonite groutwas then placed by tremmie pipe up to the surface. Six-inch steelprotective casing was installed over each well and anchored withcement. A sloping cement pad was placed around each well and theprotective casing locked with a padlock.All plume identification wells were screened in the sand and graveloutwash, except J5W13. This well was drilled into sandstone bedrockat depths of 60 feet to 75 feet. The screen is in the bedrock atdepths of 75 feet to 65 feet. The reason for this change in work planwas the presence of the saturated zone at this location in thebedrock. A monitor well screened in outwash would not yieldrepresentative groundwater samples.Table 5-1 is a summary of the construction of the plume identificationwells. A detailed description of the borings and the construction ofthe monitor wells is found in the boring logs and well constructionsummaries in Appendix C.5.5 PDJME HJK^rii-'lCKnON WELLAll newly installed REM plume identification monitor wells weredeveloped by pumping with a positive-displacement pump or by bailing.This insured full flow between the aquifer anci the well screen priorto sampling. A niinimum of 11 well volumes of water was removed fromeach well during development. U.S. EPA REM well H-713 was developedwith a bailer since it was screened in bedrock, it recover veryslowly.

SECTION 6QROUNDWftTER SAMPLING PROGRAM

6.1 SAMPLDI5 ITOC53AM6.1.1 Scope of WorkDuring the Fhase U field investigation program/ the samplingactivities included the collection and analysis of groundwatersamples in addition to the soil samples discussed in previoussections. Groundwater samples were collected from four sets ofmonitoring wells including: (1) Riase I and Phase U, U.S. EPA REMwells; (2) Wisconsin ENR wells; (3) City of Eau Claire wells; and, (4)National Presto wells. The groundwater sanple locations are shown inFigure 6-1. Chemical analyses were perform^ on 97 of these samples,of which 81 were investigative.All of the groundwater samples were analyzed by the ContractLaboratory Program (CLP) for Special Analytical Services (SAS) forcertain volatile organic compounds (in order to attain low detectionlimits).6.1 .2 Sampling MethodsTwo sampling methods were used to collect the groundwater samples.These methods included extraction with a positive displacement ISCObladder pump and a Well Wizard straddle packer system. For every 10investigative samples collected, one duplicate and one blank sanplewere also collected. Field parameters collected for each sampleincluded temperature, pH and specific conductivity. Thesemeasurements were collected in accordance with the proceduresspecified in the QAFP and the Phase II Sampling and Analysis Plan.Table 6-1 presents general data pertinent to sample collection duringPhase II. Twenty-nine U.S. EPA REM wells were sampled during thePhase U field event. Six nested wells (EW02A-C, KW03A-C), ten sourcewells (FW16-EW25) and one plume well (BW13) were sampled with the ISCObladder pump. KW13, a newly installed plume well, is installed inbedrock with a 10 foot screen. Therefore, it was not necessary tocollect the sample from EW13 with the Well Wizard. The remainingsingle point, fully screened wells were sampled with the Well Wizardstraddle packer system to simulate a nested well installation. Threesamples were collected from each of the single point, fully screenedwells from selected depths. One sample was collected at the top ofthe saturated zone, one in the middle and one at the bottom of thesaturated zone. A minimum of three well volumes were purged from eachinterval before the sample was collected.Eicfct Wisconsin CNR (WENR) wells ware sampled during the Phase Usampling event. All of the WCNR wells were sampled with an ISCObladder pump. A minimum of three well volumes were purged from eachwell before the sample was collected.

The City of Eau Claire monitoring wells were first purged with adewatering pump since the quantity of water extracted was beyond thecapabilities of either the Well Wizard or the ISCO bladder pump. Thesamples, however, were collected with the ISCO bladder pump for all ofthe City of Eau Claire monitoring wells.Four National Presto wells were sampled during the Hiase n sampling

FW04 was sampled with a Teflon bailer due to an obstructionin the well (lhase I sample collected with a bailer also) . Threeproduction wells were also sampled (W5, W6 and W7) . The productionwells were allowed to run for 15 minutes before the sample wascollected at the sampling port. A groundwater sample was also to becollected fron W-4 during Ehase 2 ; however, this well is nownonrunctioning.All sampling equipment was decontaminated prior to sampling at eachwell. Since the samples were to be analyzed for volatile organics atvery low detection limits, it was decided in the field that acetone orjnethanol would not be used in order to prevent potential, samplecontamination. The bailers were scrubbed with an alconox detergentsolution and rinsed with distilled water. In order to decontaminatethe well wizard and ISCO bladder pump, an alconox detergent solutionwas run through the pumps for an average of five minutes. The alconoxdetergent was then purged fron the pumps by running distilled waterthrough the pumps for an average of five minutes.6.1 .3 Evaluation of Effect of Sampling Method on VDC DataDuring the Riase I field effort, groundwater samples were collectedusing three different methods. These methods include extraction witha bailer (Teflon or stainless steel) , a positive displacement ISCObladder pump and a Well Wizard straddle packer system.In order to determine if differences in sampling method have anyeffect on the level of contaminants present, several wells weresampled during Riase U with two or more sampling methods.Groundwater samples were collected from PW03A, BW03B and EW03C with abailer and the ISCO bladder pump. Samples from the water table (thetop of the water column in the wen) in 13*01 (FW01X) and BW07 (HW07X)were collected with a bailer, the ISCO bladder pump and the wellwizard. This sampling will provide three sets of data having two datapoints (pump versus bailer in J3TO3) and two sets of data having threedata points (pump versus bailer versus packer in FW01 and FW07) .6.1 .4 Groundwater Level MeasurementsIn addition to the groundwater samples collected from the monitoringwells specified in Section 6.1 .2, groundwater level measurements wereobtained from all U.S. EPA REM wells, all Wisconsin ENR monitor wells,National Presto (NPI) monitor and production wells, and City of EauClaire monitor wells. All water level measurements were collected on17 August 1987 within a 6.5 hour time period. These water levelmeasurements, in conjunction with previous measurements, will be usedin refining interpretations of the numerical groundwater modeling by

providing seasonal fluctuation data for the aquifer. A third round ofgroundwater level measurements will be collected in October when thenewly installed U.S. EPA REM wells are sampled for a second time. Allgroundwater measurements collected during Riase U are Included inTable 6-2.6.1 .5 Monitoring Well Elevation SurveyDuring the period of time from 19 to 21 August 1987, the U.S. EPA REMwells were surveyed by WESTQN personnel. The purpose of the surveywas to establish references from which to measure the depth togroundwater so that the groundwater flow gradient and direction offlow could be monitored. Three elevation datum points were collectedfrom each well, including the top of the steel protective casing, thetop of the well (stainless or PVC), and the ground elevation. Themonitoring well elevations were surveyed to the nearest 0.01 foot.The monitoring well survey data is presented in Table 6-3.
