PROPOSED PHASE ffl GROUNDWATER INVESTIGATIONDU PONT-NEWPORT SITENEWPORT, DELAWARE

Gentlemen:

On behalf of Du Pont, Woodward-Clyde Consultants (WCC) has reviewed EPA'sJanuary 17, 1990 preliminary letter requesting additional work to attain additionalgroundwater data to satisfy sufficiency requirements of EPA for the Newport Site. Du Pontand WCC recognize that letter as an EPA response to the Data Sufficiency Memorandum(WCC, April 27, 1989). For the record, Du Pont and WCC anticipate comments in the nearfuture on the Data Sufficiency Supplement (WCC, November 8, 1989).

Du Pont has been responsive to EPA requests and complied with mandatedschedules fully since the Site became nominated for NP.L status. Further, Du Pont and WCChave conducted significant investigations prior to an ACO, in response to an AGO, and then aPhase H follow-up investigation at the request of EPA. With respect to the groundwaterinvestigations, which the EPA comment letter addresses, there is sufficient information toconduct a Feasibility Study (FS). The alternatives available for groundwater remedy are few,if groundwater cleanup is required. While additional data may be required for the RemedialDesign/Remedial Action (RD/RA), as part of detailed design data needs, feasibility judgementscan be made with existing information.

Du Pont and WCC have examined the record of work performed by Du Pontand WCC since the 1970's and are surprised that EPA suggests an additional major fieldprogram at this time. A summary of the more recent activities performed to date include:

Woodward-Clyde Consultants

o March 1987 - Du Pont and WCC prepared and submitted to EPA a report onthe existing prior data. The fundamental groundwater flow patterns at theSite and the parameters of concern were identified.

o September 1987 - Du Pont and WCC submitted the results of the June-August1987 Phase I field investigation which included the installation of 27 wells,surface and downhole geophysical surveys, aquifer tests (7-day) north andsouth of the Christina River, a river sediment survey, and a tidal cycle riverwater study. These reports were provided to EPA and formed a basis for theRI/FS Work Plan (WCC, July 28, 1988) approved by EPA. The results of thisPhase I study have remained largely unchanged to present for the North andSouth Disposal Areas.

o July 1987 - July 1988 - Du Pont and EPA negotiated the AGO at the Site.

o July 1988 - EPA approved the Final RI/FS Work Plan, which included a Phasfor the Remedial Investigation (RI). The work included 7 wells, as wellextensive ecological analyses of the on- and off-site marsh areas and rivers.Phase II fieldwork was completed in 1988 (sampling occurred in November andDecember, 1988).

o April 1989 - Data Sufficiency Memorandum (WCC, April 27, 1989) wassubmitted to EPA in April 1989. Sufficient data were available at this time todetermine the extent of vertical and horizontal contamination, to calculateloadings, to perform a Risk Assessment (RA) for the Site, to conduct a FS, andto develop an RD/RA Plan.

Du Pont and WCC recognize that there never will be 100 percent of datapotentially available at a Site, but, nevertheless, decisions need to be made to move forward.Data are sufficient to progress with the RA and FS process now. If EPA, however, elects to

AR308787


-3-

continue the RI, Du Pont and WCC have reviewed in detail the preliminary suggestions of EPAand are providing comments in the following sections.

Du Pont and WCC recognize that some additional information may be requiredfor the RD/RA, and, thus, Du Pont agrees to gathering these data at this time for thateventuality. Du Pont and WCC, however, strongly urge EPA to review and re-evaluate theprodigious data submitted to date, to recognize that options for remedy of groundwater arelimited, and to acknowledge that acquisition of additional data is unlikely to affect conclusionsof the FS. In the event that EPA requires a Phase III Groundwater Investigation at this time tocomplete the RI, Du Pont agrees to conduct the program conceptually outlined in subsequentsections of this letter. Work would begin on the program upon approval of the items identifiedin this letter and subsequent approval by EPA of a detailed Work Plan and schedule.

For convenience, Du Pont and WCC are responding below on an item by itembasis to the six items numbered in the January 17, 1990 EPA letter.

ITEM NO. 1

The nine approximate locations for additional three-well cluster drilling sitesproposed by EPA are shown on Figure 1. For discussion purposes, WCC numbered each ofthese nine locations. As discussed during our meeting of February 5, the EPA-proposed 27wells are excessive and are not warranted either "by regulation" or technical merit. If theEPA feels that additional field investigations are necessary, Du Pont would agree to installwells at locations labeled A through F (see Figure 1) as part of a Phase III investigation,because they could benefit the RA and RD/RA program. These locations will be discussed asappropriate in the following sections. For discussion purposes, Du Pont and WCC are providingsummary figures of measured total concentrations of significant parameters (Figures 2 through13). Further, the data (Tables 1 through 10) and summary figures for the total meanconcentration of each of the parameters are presented in Figures 14 through 16. These figuresprovide the current best estimate of probable total concentration for each parameter of

AR308788


concern at each well. These data were provided previously in the Data SufficiencyMemorandum, and are included here, again, for ease of reference.

Proposed EPA Locations 1 and 2: These two proposed locations are located atthe northeast perimeter of the Newport Site. Based on the February 5, 1990 meeting, Du Pontand WCC understand that EPA's purpose for these six wells is to characterize better theextent of any possible groundwater contamination in this area of the Site both on and off theproperty. Because the Newport Site property extends east of James Street and only onepermeable Potomac Formation water-bearing zone is likely to be present in this area (based onboring logs of MW-17B and MW-18B), the six EPA-proposed wells are considered excessive toachieve this goal. Based on the physical boundaries of the historic operations area, which wasbounded by James Street, and the likely groundwater flow directions in both the Columbia andPotomac Formations in this area, Location A (Figure 1) is presented by Du Pont. Du Pontagrees to two wells, one completed in the shallow zone Columbia Formation and one in theintermediate zone Potomac Formation.

Both contaminant concentration gradients and the groundwater flow directiasuggested by the existing data support drilling at the Du Pont recommended location. Thespacing of the isoconcentration contours shown in the Data Sufficiency Memorandum suggestthat non-exceedances of Maximum Contaminant Levels (MCLs) may be demonstrated atLocation A. Chemical data for the groundwater sample from DB-2, a temporary piezometernot designed as a monitoring well, cannot be used for RI evaluation purposes because the dataare unreliable. Furthermore, two closely positioned locations in this area are consideredunnecessary. Because James Street does not represent a hydrogeologic or property boundaryrequiring contaminant concentration data for RA purposes, we see no reason to drill at EPALocation 1 (Figure 1). Instead, the Du Pont Location A is anticipated to provide groundwaterchemistry data reflecting non-exceedances of the ARARs. Du Pont is willing to drill at alocation in this general area.

SR308789 A

No deep zone Potomac Formation well is required at Location A becauseexisting data suggest that only one water-bearing zone in the Potomac Formation is present inthis part of the Site (see MW-17B and MW-18B boring logs).

Proposed EPA Location 3: Our understanding from the February 5, 1990meeting is that EPA requests drilling at this off-site location to obtain better resolution of theouter edge of the contaminant plume suggested by some of the existing monitoring wells alongthe eastern boundary of the Site. Upon close scrutiny of the specific monitoring wellsconstructed along this eastern boundary, however, it is readily apparent that the outer edge ofthe contaminant plume boundary can be estimated in the Potomac Formation without drillingadditional wells. The MCL exceedances reported from any of the groundwater samplingepisodes were for barium only in the Columbia Formation (Figure 4). These exceedancesoccurred in existing monitoring wells MW-16A, MW-18A, MW-14, and MW-7A along thiseastern perimeter. There are no exceedances for any Potomac Formation wells in this area(Figures 2, 3, and 5 through 16). Consequently, in lieu of the EPA's proposed three-well clusterLocation 3, Du Pont agrees to drill a shallow zone Columbia Formation monitoring well atLocation B and two additional shallow zone Columbia Formation monitoring wells at LocationsC and D (see Figure 1). These three Columbia Formation wells would provide better definitionof the barium concentrations in the shallow zone along the eastern perimeter of the Site. Inaddition, due to groundwater flow directions in the Potomac Formation, Du Pont agrees todrill a Potomac Formation well at Location B to supplement the Location A drilling andprovide a downgradient well from MW-17B and the historic operations area of the Site.

A well in the deep zone Potomac Formation, as proposed by EPA, is consideredunnecessary. The bottom of contamination exceeding MCL requirements is restricted to theshallow zone Columbia Formation. Inspection of chemistry of the intermediate zone PotomacFormation (Tables 1 through 10; Figures 3, 5, 7, 9, 11, and 13), which is summarized in Figure15, reveals no exceedances in MW-18B and MW-7B. Further inspection of the deep zonePotomac Formation chemistry (Tables 1 through 10 and Figure 16) also reveals no exceedancesat this location. For RI purposes the bottom of contamination has been adequately definedalong the eastern boundary of the Site.

BR308790


Proposed EPA Locations 4 and 5: According to the February 5, 1990discussions, these EPA locations were prompted by exceedances of the 10 ppb cadmium MCLreported for the perimeter monitoring wells MW-11, MW-6A, MW-6B, and MW-6C, andparticularly by the 130 ppb reported at MW-6A. The value of 130 ppb is a statistical outlier atthe 90 percent confidence level, in accordance with EPA procedures for identifying outliers(Statistical Analysis of Groundwater Monitoring Data at RCRA Facilities, Interim FinalGuidelines, EPA, February 1989). Based on the previously submitted groundwater chemistrydata for the two Necastro residential wells located immediately adjacent to the southerncorner of the Newport Site, which showed no MCL exceedances, Du Pont and WCC concludethat no additional monitoring wells are needed in this area of the Site.

The only parameter for which any MCL exceedances have been reported forany of the five monitoring wells in this area of the Site is cadmium. The figures submitted aspart of the Data Sufficiency Memorandum displayed only the highest reported total ordissolved parameter concentrations from any of the sampling events. As shown in theattached Figures 6 and 7, the exceedance of the 10 ppb MCL for cadmium occurred in the tPotomac Formation wells MW-6B and MW-6C (Figure 16) only during the initial sampliepisode in August 1987. The calculated means of measured concentration do not exceed 10ppb (Figures 15 and 16). The initial slight exceedances (12 ppb at MW-6B and 17 ppb atMW-6C) were followed by several sampling episodes in which cadmium was not detected (lessthan 5 ppb). These initial 12 ppb and 17 ppb concentrations are considered anomalous dataassociated with initial sampling following construction of the monitoring wells. Thus,additional monitoring wells in the intermediate and deep zone Potomac Formation in thisvicinity are not warranted.

With regard to the cadmium exceedances in the shallow zone wells, MW-6A,MW-11, and MW-13, all but one reported concentration are within a few parts per billion ofthe cadmium MCL. The one exception is the reported 130 ppb total cadmium for MW-6Aduring the December 1988 sampling episode. As stated previously, the measured concentrationis a statistical outlier (at the 90 percent confidence level) and should not be used for anevaluation of whether additional wells would be required. Furthermore, dissolved cadmium

flR3Q879l


-7-

was reported as a non-detection for MW-6A during the same sampling episode. Thus, thecadmium exceedances in the Columbia Formation at this perimeter location are consideredextremely marginal. This is consistent with the non-exceedances from the immediatelyadjacent off-site Necastro residential wells along Old Airport Road. Combined with theprobable direction of Columbia Formation groundwater flow toward the wetlands on theDu Pont property in this area, rather than an off-site direction, the Du Pont property boundaryalong Old Airport Road is considered coincident with the approximate edge of the shallowgroundwater plume containing any MCL exceedances. Additional Columbia Formationmonitoring wells, therefore, are not warranted in this vicinity of the Site perimeter. Thesouthern boundary of the groundwater plume can be estimated horizontally and vertically withthe existing data.

Proposed EPA Location 6: This three-well cluster location is requested byEPA south of the Christina River. Minor exceedances of the cadmium MCL in both wellsMW-19A and MW-19B, as well as minor concentrations of tetrachloroethylene (PCE) andtrichloroethylene (TCE) in the shallow zone well MW-19A are understood to be the basis forthis proposed EPA cluster of three wells. The PCE and TCE identified in the shallow zone atMW-19A are not considered to be related to the Site. The probable source of thesecontaminants is to the south. (Refer to Data Sufficiency Memorandum on direction of shallowzone groundwater flow.) These available shallow zone piezometric surface data suggest thatthe probable shallow Columbia Formation groundwater flow direction is toward the wetlandson the Du Pont property in this area. The lack of MCL exceedances in any of the ColumbiaFormation private wells along Old Airport Road also support the contention that groundwatercontaminants associated with past operations at the Newport Site have not influenced theColumbia Formation groundwater quality in the private wells along Old Airport Road.

The levels of cadmium and TCE concentrations in monitoring well MW-19Aare so low that no additional Columbia Formation groundwater chemistry area are considerednecessary for the RA or the FS, or to estimate the edge of contamination. Data are sufficientto define concentration gradients in the area; thus, these data would be used to define theouter edge of the cadmium and TCE concentrations. The existing groundwater chemistry data

8R308792


for the Columbia Formation in this vicinity of the Site are, therefore, considered sufficient.No additional Columbia Formation monitoring wells are considered necessary by Du Pont andWCC for this area.

The cadmium exceedance of the MCL in the Potomac Formation at theMW-19B well location can also be addressed without drilling additional wells. The two sampleswere collected shortly after installation of the well. The reported values may be an artifactof perturbations due to drilling. Moreover, there are no MCL exceedances in the PotomacFormation private wells along Old Airport Road and the existing potentiometric surface datafor the Potomac Formation suggest a southeastward or eastward flow direction from theMW-19B location across the Du Pont property rather than toward the private wells along OldAirport Road. In combination with the minor exceedance of cadmium in MW-19B, noadditional data for the Potomac Formation are considered necessary for preparation of the RAor the FS. Thus, no additional intermediate zone Potomac Formation monitoring wells areconsidered warranted by Du Pont and WCC in this vicinity of the Site.

The nearby deep zone Potomac Formation well DML-7 (Figure 16) defines tbottom of contamination of the Site on the southwestern border. No deep zone well, asproposed by EPA, is warranted.

Proposed EPA Location 7: This EPA three-well cluster location is positionedsouthwest of the Site boundary on the north side of the Christina River. In the PotomacFormation, the only parameter of concern is cadmium, with slight exceedances of the MCL inonly one well, DM-6 (Figures 14 through 16, Tables 1 through 10). The other peripheralmonitoring wells in this area (MW-3B and MW-3C), display no MCL exceedances for anyHazardous Substances List (HSL) parameters (Figures 3, 4, 6, 7, 9, 10, 12, 13, 15, and 16), Inaddition, the groundwater flow direction in the Potomac Formation in this part of the Site issoutheasterly across the Christina River toward other existing Site monitoring wells onDu Pont property. Based on the only slight exceedance of one parameter, the absence ofexceedances in MW-3B and MW-3C, and this flow direction, no additional off-site perimeter

SR308793


-9-

monitoring wells in the intermediate and deep zones of the Potomac Formation are warrantedto conduct the RA or the FS. Consequently, no additional Potomac Formation monitoringwells are necessary.

Existing periphery shallow zone monitoring wells near the EPA Location 7show MCL exceedances for zinc, cadmium, TCE, and PCE. Although the groundwater flowdirections in this area are toward the Christina River, rather than off-site, Du Pont agrees toinstall one shallow zone Columbia Formation monitoring well (Location E) near EPA Location7 to delineate further the edge of the plume.

Proposed EPA Location 8: Based on the February 5, 1990 meeting, EPAselected this three-well location to evaluate in more detail the source of the PCE and TCEconcentrations in the area of existing monitoring wells MW-1A and SM-2. Du Pont and WCCconsider these concentrations associated with groundwater flow directions driven by pumpageof WW-13 and WW-11 along with natural flow under non-pumping conditions. The organicssource was the historical operations, documented in the Data Sufficiency Supplement, locatedto the northeast of these wells, not the area of the Holly Run Plant. Thus, no additionalmonitoring wells are considered necessary or warranted in the vicinity of EPA Location 8.

Proposed EPA Locations 9: This EPA three-well cluster location is positionedoff-site to the northwest beyond the railroad tracks. By virtue of its position upgradient fromany historical operations at the Newport Site it is considered a background location. Theindicator parameters of the Site (barium, cadmium, and zinc) that have been identified in wellsWW-11 and WW-13 from the intermediate zone Potomac Formation might be elevated abovethe natural background levels of the area. Thus, these concentrations would likely be due topumping activities, as previously described (Data Sufficiency Supplement, November 1989).Because of potential surface sources of contamination upgradient of the Site, e.g., the railroadtracks, Du Pont agrees to install a shallow zone Columbia Formation well in the vicinity ofLocation F. However, two additional Potomac Formation wells are considered unnecessary.

ITEM NO. 2

Groundwater chemistry data trend analyses over time were conducted by WCCand the pertinent aspects are addressed in the preceding section. Graphs showing trends ofparameters reported prior to 1987 to present are attached (Appendix A). Tables 1 through 10and Figures 2 through 13 provide time data since 1987. Inspection of these graphs reveals thatfor many of the wells there is a decrease in concentration over time of one or moreparameters since installation of the wells.

To provide additional confirmation, Du Pont agrees to collect and analyzesamples from all pertinent periphery wells installed during Phases I and II, followinginstallation of the additional agreed to Phase III wells.

ITEM NO. 3

The background groundwater chemistry issue is addressed in the Item No,section under Location 9. Specific delineation of background chemistry will be providedEPA with the results of the Phase III Groundwater Investigation.

ITEM NO. 4

On the basis of comparison between the existing groundwater chemistry datafor the Newport Site and the MCLs or other ARARs, no other HSL parameters (besides barium,cadmium, zinc, TCE, and PCE) are considered likely to pose a groundwater risk. One possibleexception might be arsenic, due to the DB-2 groundwater data. As discussed previously,however, these data are not considered useable to represent the actual groundwater chemistryat the test boring location. For discussion purposes, data on arsenic were summarized for thisletter report (Figures 2, 3, and 14 through 16; Tables 1 and 2). However, additional data to becollected during the Phase HI of the RI work will be necessary before inclusion of arsenic, orother chemicals, and the final selection of risk chemicals, is made. For RI purposes, there areno other indicator chemicals.

ITEM NO. 5

Contemporaneous hydrographs for the Christina River and water elevations ofnumerous Site monitoring wells representative of both the Columbia and Potomac Formationsduring several tidal cycles were previously submitted to EPA in the Work Plan (WCC, July 28,1988). Evaluation of these hydrographs will be discussed with the results of the Phase IIIGroundwater Investigation and in the RI report. No additional continuous water levelmeasurements of the Christina River or any Site monitoring wells is warranted.

As discussed during the meeting of February 5, the data present in the DataSufficiency Memorandum on heads at low and high stages of the tide show that vertical-gradient directions are unaffected by tide stage. Further, as has been shown numerous times,mean tidal-stage head measurement provides the basis for loading calculations, flow rates anddirections. Mean tide measurements will be used in the RI Report.

ITEM NO. 6

As discussed on February 5, 1990, the PCE and TCE concentrations at MW-1Aand SM-2 might suggest contaminant transport directions different from groundwater flowdirections. However, as explained above, historical supply well pumpage accounts for this.

The other area at the Newport Site where isoconcentration plots might suggestcontaminant movement in a direction different than apparent groundwater flow is in theColumbia Formation near monitoring wells SM-4 and MW-8 on opposing sides of the ChristinaRiver. Scrutiny of the previously submitted stratigraphy data shows that the Christina Riveris incised only about half-way through the approximately 25-foot thickness of the ColumbiaFormation at the Site. In conjunction with the available water level elevation data for themonitoring wells and the Christina River, the potential exists whereby groundwater in theColumbia Formation might flow under the Christina River from the SM-4 area to the MW-8area. This would possibly offer an alternate explanation for the similarity of the shallow zoneColumbia Formation groundwater in the two areas of the Site.


As discussed above, Du Pont and WCC do not feel that additional RI work isneeded to perform the RA or FS. However, in a spirit of cooperation, Du Pont agrees toconduct the Phase III efforts described in this letter. Following receipt of written commentsfrom EPA on the Data Sufficiency Supplement and approval by EPA of this conceptualPhase III groundwater program, Du Pont will initiate preparation of a Phase III RI Work Planaddressing all additional non-wetlands investigations.

Please do not hesitate to call the undersigned or Mr. Tim Hill at Du Pont ifyou have any questions.

Very truly yours,
