EXECUTIVE SUMMARY
There are two operable units established at the TH Agriculture & Nutrition (THAN) Superfund Site inMontgomery, Alabama. Operable Unit I (OU-1) consisted of an interim groundwater remedy and OU-2addressed the final groundwater remedy, as well as the soil and sediment remedy. The interim remedy forOU-I consisted of groundwater extraction at the downgradient edge of the Site with discharge to the localpublicly owned treatment works (POTW). The final groundwater remedy included enhancedbioremediation using HRC and EHC injections, which accelerates the attenuation of contaminant levelsbeyond that expected with natural attenuation. The soil and sediment remediation consisted of theexcavation and consolidation of impacted soil and sediment, placement within a treatment area on site,and in-place treatment using reductive dechlorination.
The soil and sediment remediation has been completed and performance standards have been met. TheOU -I interim groundwater remedy, which consisted of extraction and discharge to the local POTW, hasbeen superceded by the final remedy (enhanced bioremediation) pursuant to Section IV. B Task III of theSOW for OU-2 Consent Decree. . Both the HRC and EHC injections have been completed and thegroundwater monitoring data indicate that groundwater remediation has been adequately completed.
The soil and groundwater remedies at the THAN Site are considered protective of human health and theenvironment. Although offsite groundwater migration of site contaminants is possible, data to date do notshow this to be the case and groundwater at the Site will continue to be monitored in accordance with thePerformance Standards Verification and Monitoring Plan for OU-2. No domestic or other wells in theaffected area are currently being used.

1. INTRODUCTION
The performance of the remedies that have been implemented at the T.H. Agriculture and Nutrition(THAN) Site in Montgomery, Alabama is evaluated in this second Five-Year Review. The review wasinitiated in February 2007 with a kick-off meeting and it was completed in September 2007. Reports andassociated data were reviewed as part of this five year review process. The THAN Site was placed on theNational Priorities List (NPL) in August 1990. A groundwater recovery system was installed betweenOctober 1997 and January 1998, and operated thereafter as an interim remedial action in accordance withthe Record of Decision (ROD) for Operable Unit One (OU-I). The ROD for Operable Unit Two (OU-2)addressed final remedies for contamination in all media, including soils, sediment, surface water, andgroundwater. Continuous operation of the groundwater recovery system ceased in March 2002 just priorto implementing the enhanced bioremediation of groundwater using Hydrogen Release Compound(HRCTM) for OU-2 in accordance with the EPA approved Work Plan for Enhanced Bioremediation ofGroundwater. The enhanced bioremediation of groundwater using HRCTM began in March 2002,followed by four sampling events completed in June 2003, and a follow-up sampling event in September2004. Bioremediation of groundwater was further enhanced using EHCTM which was performed in June2005 following a 3-week injection period. The enhanced bioremediation for soil and sediment began inJuly 2002 and was completed in September 2004.
The purpose of the Five-Year Review is to determine if the site remedy is protective of human health andthe environment. The methods, findings, conclusions, and significant issues identified during the revieware documented in this report. In addition to the findings and conclusions of the reviews, deficiencies (ifany) are identified and corrective actions (if any) are recommended. This is the second Five-Year Reviewfor the THAN Site.
This review is required by statute. The United States Environmental Protection Agency (EPA) mustimplement Five-Year Reviews consistent with the Comprehensive Environmental Response,Compensation, and Liability Act (CERCLA) and the National Oil and Hazardous Substances PollutionContingency Plan (NCP). CERCLA § 121 (c), as amended, states:
If the President selects a remedial action that results in any hazardous substances, pollutants, orcontaminants remaining at the site, the President shall review such remedial action no less oftenthan each five years after the initiation of such remedial action to assure that human health andthe environment are being protected by the remedial action being implemented.
The NCP part 300.430(f)(4)(ii) of the Code of Federal Regulations (CFR) states:
If a remedial action is selected that results in hazardous substances, pollutants, or contaminantsremaining at the site above levels that allow for unlimited use and unrestricted exposure, the leadagency shall review such action no less often than every five years after the initiation of theselected remedial action.
This Second Five Year Review Report was conducted by EPA with the support of the PotentiallyResponsible Parties (PRPs), in accordance with applicable EPA guidance. The trigger action for thisreview was the signing of the First Five Year Review Report on September 30, 2002. That first reviewwas performed by the US Army Corps of Engineers for the USEPA and with the assistance of the PRPs.

3. BACKGROUND
The THAN Site is located on the west side of the city of Montgomery, Montgomery County, Alabamaapproximately 2 miles southwest of the Alabama River and 1,600 feet west of Maxwell Air Force Base.The Site is adjacent to and accessed by Highway 31-82. A Site Location Map is included as Figure I.
The Site encompasses an area of approximately 16.4 acres. The Site is comprised principally of twoadjacent properties, which are identified as the THAN property and the Atofina Chemicals, Inc. property.The properties have been used in the past for formulation, packaging, and distribution of pesticides,herbicides, and other industrial/water treatment chemicals. The Site is currently unoccupied and there areno plans to develop or reoccupy either property. The Site also includes impacted areas to the west(Kruger Commodities) and the adjacent ditch to the east located between a railroad and Highway 31-82.Principal adjacent land uses are commercial and industrial, although some of the neighboring propertiesare undeveloped and there is a mobile home park located northwest of the Site. The Site is relatively flat.The nearest surface water features include the West End Ditch and Catoma Creek, both of which aretributaries of the Alabama River, and small ponds on adjacent property.
The THAN property is comprised of I 1.6 acres on the northern part of the Site. This property was firstdeveloped by Wittigen Chemical Company as a sales, packaging, and storage facility for water treatmentand plating chemicals. THAN, which was then known as Thompson Hayward Chemical Company,bought the facility in 1966 for storage and distribution of agricu,ltural and industrial chemicals. THAN, awholly owned subsidiary of Phillips Electronics North America Corporation, closed the facility in 1978and leased it for various time periods before selling it in 1986 to Williamson Industries, Inc. THANpurchased the property back from Williamson Industries, Inc. in 1994 and presently owns the property.Arkema currently leases the property and will continue to do so until the remediation is completed.
The Atofina Chemicals, Inc. property is comprised of 4.8 acres on the southern part of the Site.Montgomery Industries first developed this property. Atofina Chemicals, Inc., know as PennwaltCorporation at that time and later as Elf Atochem North America, Inc., purchased the property in 1951and used it as a chemical blending and distributing facility. Astro Packaging, Inc. bought the property in1979 and leased it to Industrial Chemicals. Atofina Chemicals, Inc. subsequently leased the propertyfrom Astro Packaging. Atofina Chemicals, Inc. purchased the property back from Astro Packaging, Inc.in December 1999 and presently owns the property. Atofina Chemical, Inc changed it's name to Arkema,Inc in 2005. Legacy Site Services, LLC (LSS) is acting as Arkema's exclusive agent for performing allremedial activities required under the Consent Decree.
Waste materials were found on the THAN property in October 1980 during an inspection of the THANproperty by the Alabama Water Improvement Commission. The Site was expanded to include both theTHAN and Atofina Chemicals, Inc. property after it was discovered that contamination from the AtofinaChemicals, Inc. property was impacting the THAN property. THAN excavated wastes and contaminatedsoils from 13 burial areas and collected contaminated groundwater, treated it, and discharged it topublicly owned treatment works (POTW) in 1981. The Site was placed on the National Priorities List(NPL) in August 1990. Atofina Chemicals, Inc. agreed in March 1991 to perform a Remedial

3: Background Second Five-Year Review Report
InvestigationlFeasibility Study (RIfFS) pursuant to the terms of a Consent Order issued by the EPA. TheROD for OU-I was issued April 1995. The Final Construction Report for OU-I was released in February1998. The ROD for OU-2 was signed September 1998.
Primary contaminants of concern in the groundwater at the Site are pesticides, including hexachlorides(BHCs) (alpha, beta, delta, and gamma), and herbicides; volatile organic compounds (YOCs) includingtrichloroethene (TCE) and tetrachloroethene (PCE) and their daughter products.
Groundwater is used as a drinking water source, as well as for domestic and industrial use, in the generalvicinity of the Site. However, no domestic or other wells within the affected area of the Site are currentlybeing used. Regional and local groundwater use was described in the Remedial Investigation Report(Eckenfelder Inc., June 1993). Groundwater flow is generally north at the Site with slight variationstoward the northeast or northwest depending on the time of yea~ and recent precipitation.
Primary constituents of concern (COCs) in soil and sediment at the Site are pesticides, includingdichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethylene (DOE), dichlorodiphenyldichloroethane (DOD), and toxaphene; and metals such as arsenic.
Additional information pertaining to the Site is available in the numerous documents prepared over theyears to address various investigations, feasibility studies, treatability studies, risk assessments, remedialdesign, and construction, and monitoring. These documents are available for review at the publicrepository (The Rufus A. Lewis Regional Library in Montgomery), or through the USEPA Region 4.

4. REMEDIAL ACTIONS
4.1 Remedy Selection
The ROD for the OU-I at the Site was signed April 1995. The selected remedy was an interim remedy toemploy the use of extraction well(s) combined with treatment. The primary objective of the interimremedy was to prevent further migration of contaminated groundwater from the Site and to initiategroundwater restoration pending completion of the RIIFS and implementation of the final remedial action.The major components of the OU-I selected interim remedy were:
• Extraction of groundwater to contain contamination within the boundaries of the Site, and
• Discharge of water to the local POTW for treatment.
Treatment of the discharged water occurred at the local POTW. Contingent remedies allowing on-Sitetreatment and on-Site discharge via reinjection or infiltration were also provided in the OU-I ROD ifdischarge to the local POTW was found to be technically impracticable or could not be implemented in acost-effective or timely manner. The contingent remedies have not been used.
The ROD for OU-2, signed February 1998, provides for the final action for the cleanup of thecontamination in the soils, sediment, and groundwater at the Site. The major components of the selectedremedy were:
• Designation of the areal extent of contamination as a Corrective Action Management Unit (CAMU);
• Excavation of soil and sediment from those areas exceeding cleanup standards;
• Backfilling of the excavated areas;
• On site biological treatment of the excavated soils and sediments until cleanup standards are met;
• Revegatation of the treated soils and sediments on Site;
• Institutional controls which include fencing and deed restrictions limiting Site use for industrialpurposes only; and,
• Continuation and evaluation of the interim remedial action and enhancing the biodegradation that hadbeen established using enhanced bioremediation agents until groundwater performance standards aremet.
The groundwater performance standards in the ROD for OU-2 are based on drinking water standards.Periodic groundwater monitoring was required for compliance testing and to determine the effectivenessof the selected remedy. The OU-2 ROD stated that groundwater monitoring shall be conducted quarterlyat the Site for the first year of the remedial action (1998) and at least twice annually until the performancestandards are met at the point of compliance (POC). The POC was set at the property boundary.
The OU-2 ROD states that groundwater modeling predicted that the contaminants carbon tetrachloride,trichloroethene, and endrin would most likely control the length of the cleanup action; and that thecleanup could take as long as 30 years, based on carbon tetrachloride reaching its Maximum Contaminant

4: Remedial Actions Second Five·Year Review Report
Level (MCL) in the lower portion of the surficial aquifer. However, it was believed that the groundwaterremedy would require less than 30 years because of the intrinsic attenuation due to biodegradation.
Based upon approximately 5 years evaluating the operation and effectiveness of the groundwater recoverysystem (GWRS), pursuant to Section IV. B Task III of the SOW for OU-2 Consent Decree, theresponsible parties submitted a Work Plan for Enhanced Bioremediation of Groundwater.
The Work Plan was submitted as an Addendum to the Final Design Submittal for the Interim RemedialAction (OU-I) for EPA approval. This Work Plan, using enhanced bioremediation of the groundwaterwith injection of hydrogen-releasing compound (HRCTM), was approved and its implementation began inFebruary 2002. This was an innovative approach to supplement the interim groundwater remedy basedupon asymptotic levels observed which established the final remedy in accordance with the ConsentDecree for OU-2. The enhanced bioremediation approach is intended to achieve biodegradation ofcarbon tetrachloride (CT) and trichloroethene (TCE) in the groundwater at a more rapid rate than is beingachieved by natural biodegradation and extraction combined, and thereby more rapidly achieve theperformance standard for these chemicals. The GWRS has been shut down while the enhancedbioremediation system is being implemented to avoid removal of the injected nutrients in pumpedgroundwater, as well as minimize dissolved oxygen in groundwater. Dechlorination of the COC's ingroundwater requires anaerobic conditions be maintained in the aquifer. Following the injection,groundwater was and continues to be monitored from wells within and downgradient of the treatmentarea. The enhanced bioremediation of groundwater using HRCT~ was later supplemented by EHCTM (amaterial composed of controlled-release solid carbon and zero-valent iron (ZVI) particles) to furtheraccelerate the biodegradation of the contaminants in groundwater.
Performance standards for soil and sediments were established for five constituents - DOD, DOE, DDT,toxaphene and arsenic. The soil and sediment performance standards in the ROD for OU-2 were based ona human-health risk industrial use scenario. The soil and sediment was required to be treated untilverification samples indicated compliance with the performance standards. Verification sampling wasperformed in accordance with the Performance Standards Verification Plan and specification Section02300, Treatment of Excavated Soil and Confirmation Sampling, submitted as part of the Final DesignSubmittal for OU-2.
A contingent remedy, which consisted of the off-Site disposal of impacted material, was available for thisSite. This contingent remedy was to be implemented if it was determined that the soil and sedimentperformance standards could not be met though biological treatment in a timely manner or if the treatmentprocess becomes impracticable. Milestones of 50 percent reduction after I year and performancestandards after 2 years were established in the ROD for DDT and toxaphene as a basis for potentiallyinvoking the contingent remedy. Additional criteria were also established for highly impacted materialand inorganic COCs (arsenic). Based on the res.ults obtained during the RA for soil and sediment, thecontingent remedy was not invoked.
4.2 Remedy Implementation
The GWRS selected for the groundwater remedy in the initial OU-I ROD was comprised of oneextraction well with a submersible pump, a force main, a discharge manhole, and a computerizedoperating and monitoring system. The extraction well is located near, the northern boundary of the Site,approximately at the midpoint of the east-west extent of the northern boundary. The direction of the
4-2
4: Remedial Actions Second Five-Year Review Report
groundwater flow at the Site before the recovery system was installed was northward. The force main is aburied 3-inch diameter, Schedule 40 PVC pipe. Groundwater from the recovery well was pumped intothe force main to the discharge manhole located just outside of the east boundary of the Site. Thedischarge manhole is the point of connection to a City of Montgomery sanitary sewer line. Groundwaterflows from the discharge manhole to POTW of the City of Montgomery through the sanitary sewer line.The sanitary sewer at its juncture with the discharge manhole is buried 8-inch diameter vitrified clay pipe.Flow meters are installed at three locations within the piping system to monitor flow and check for leaks.No significant changes have been made to this system since it was initially installed.
Based upon approximately 5 years evaluating the operation and effectiveness of the OU-I GWRS andpursuant to Section IV. B Task III of the SOW for OU-2 Consent Decree, Arkema submitted a Work Planfor Enhanced Bioremediation of Groundwater as the final remedy. As discussed in Section 4.1, theHRC™ injection was implemented in February 2002 over approximately a four-week period followed byfour groundwater monitoring events over a 14-month period. The HRC treatment area is shown inFigure 4. The EHC™ injection occurred over a three-week time span that was completed in June 2005,followed by four groundwater monitoring events over a one-year period. The injection of HRC™ andEHC™ were accomplished using standard drilling direct-push (Geoprobe™) methods. Both additiveswere injected in the upper sand aquifer of the saturated zone (15-35 ft below ground surface (bgs».HRC™ was injected using the bottom-up direct-push approach, while EHC™ injection was conductedusing the top-bottom direct-push method.
The soil and sediment were consolidated into an on-Site treatment cell that was treated using the patentedDaramend® enhanced bioremediation process implemented by Adventus. Approximately 2,850 cubicyards of soil and sediment were placed in the on-Site treatment cell. The cell was then divided intotwelve zones for monitoring of progress using a grid system to identify sample collection zones (seeFigure 2). Each zone was sized to consist of approximately 300 cubic yards (roughly 360 tons) ofmaterial. To maximize treatment efficiency and to minimize the occurrence of isolated areas needingcontinued treatment, soil and sediment were placed within the treatment cell in a segregated fashion basedon constituent concentrations determined during the RI and pre-construction investigations. Furthermore,sediment from the stormwater sewer system was collected using jet-rodding. Due to the presence ofelevated levels of constituents that may affect the treatment time of the bioremediation process, thestormwater sewer sediment was segregated from the treatment cells and disposed off-Site. Followingconstruction of the treatment cells, drainage improvements were implemented to minimize potential offSite erosion (see Figure 3).
A pilot test was conducted from Spring 2001 to early 2002 to optimize the Daramend® amendment priorto full-scale implementation. Baseline sampling for the full-scale treatment cell occurred in early August2002 just prior to start of the soil and sediment treatment. Interim performance· monitoring wasconducted at periodic intervals, and performance sampling events occurred in September 2002 (after 3treatment cycles), November 2002 (after 5 treatment cycles), July 2003 (after 9 treatment cycles),September 2003 (after 12 treatment cycles), and July 2004 (after 15 treatment cycles). A final samplingevent was completed in August 2004. In March 2006, both EPA and ADEM concurred that the soil andsediment remedy had been completed in accordance with all the requirements of the ROD and theConsent Decree (CD).
4.3 System Operations
Operations and maintenance (O&M) at the THAN Site have been ongoing for the past five years. Thegroundwater extraction well and monitoring well systems have been maintained in a readiness condition
4: Remedial Actions Second Five-Year Review Report
and the treatment cell where soil and sediment were remediated has been revegetated and mowed whennecessary.
Total O&M costs for the past five years through June 2007 are $685.000. Annual O&M costs aresummarized in the following table:

These annual costs are lower than those reported in the First Five Year Review. which ranged from about$270,000 to a high of $411,000. During those first five years, the annual O&M costs were relativelyconsistent at around $280.000 per year with the exception of 1999 when the costs increased to about$411.000 due to extensive system trouble shooting and maintenance due primarily to Iightning strikes.The groundwater extraction system was shut down in 2002 when the enhanced bioremediation activitieswere initiated. O&M costs for the past five years have also remained largely consistent. In general. theseannual costs are lower than those anticipated during the Feasibility Study phase for this Site because alower fee for discharge of extracted groundwater was negotiated with the Montgomery Sanitary SewerBoard.

5. PROGRESS SINCE LAST REVIEW
No deficiencies were noted in the First Five Year Review Report. Recommendations in that reportincluded assessment of groundwater data from the enhanced bioremediation monitoring activities. TheEPA further stated that the groundwater recovery system should be restarted if groundwaterconcentrations did not decrease adequately. Last, the report recommended that in accordance with theROD for OU-2 that once performance standards have been met at the point of compliance (POC),groundwater concentrations detected downgradient of the Site be evaluated to determine whether naturalattenuation is capable of meeting performance standards or if additional action is warranted.
The groundwater quality at the Site has improved substantially since the RI process began in 1991,primarily because of natural degradation of the compounds of interest. Natural attenuation, coupled withremoval of constituent mass during the period of February 1998 to March 2002 by the GWRS, hasreduced concentrations of VOCs in all except a few limited areas to levels that have either achieved or areapproaching compliance with the groundwater performance standards. The implementation of the finalremedy using HRCTM and EHC™ has demonstrated that enhanced biodegradation is capable of achievingthe performance standards set forth in the ROD for OU-2. The groundwater monitoring program hasbeen modified from that outlined for OU-l in accordance with the procedures described in the approvedWork Plan for Enhanced Bioremediation of Groundwater (September 2001) prepared pursuant toSection IV. B Task III of the SO~ for OU-2 Consent Decree. Analytical data have shown evide::lce ofVOC and pesticides reduction in groundwater following those injections in the groundwater monitoringevents. Most COCs are nearing or below MCLs based on the last groundwater sampling event in July2006. Currently, VOC concentrations in the monitored area have been reduced to levels below theperformance standards at the point of compliance. Additionally, pesticide concentrations have beensignificantly reduced to below performance standards for all pesticides except dieldrin.
The data presented in these reports indicates that groundwater concentrations have substantially decreasedand that start up of the recovery system or additional action downgradient of the Site are not warranted.However. groundwater will continued to be monitored based on a program agreed to by the responsibleparty and the agencies in accordance with the current conditions. At a minimum, additional monitoring isrequired to complete the Performance Standards Verification Plan for groundwater. The total volume ofgroundwater pumped by the GWRS to date is about 120 million gallons. The GWRS was operatingsatisfactorily when shut down and no problems are anticipated if it is started up again should it be deemednecessary.
Upon review of the data (refer to Section 6.4 and the sampling data in Attachment C) as a whole, it wasagreed among the involved parties, including EPA, that the remedial action objectives for the soil andsediment treatment have been adequately met. In addition. it should be noted that institutional controlsare in place at the Site (i.e., fencing, and Notice to Successors-in-Title,). Deed restrictions are currentlybeing formalized between Arkema, THAN. EPA and ADEM. Once completed they will be recorded inthe Recorder's Office or Registry of Deeds in Montgomery County, State of Alabama. The deedrestrictions must be in place prior to Arkema submitting for a Certification of Completion of the Work, asdefined in paragraph 51 of the OU-2 Consent Decree. A copy of the Notice Documentation is included in
6-1
Attachment G. No current plans are anticipated to develop the Site for occupancy. Final grading andestablishment of a vegetative cover over the treatment cell were completed in September 2004 and caneasily be checked during future Site activities and any problems rectified. Finally, tentative plans are inplace to demolish the buildings on both properties at the Site. When completed, this will significantlyreduce the potential for trespassing at the Site.
The Protectiveness Statement from the First Five Year Review reads as follows:
"Prior to the March 4, 2002 shutdown of the groundwater recovery system, thegroundwater remedy atthe THAN Site was protective of human health and theenvironment. By maintaining a gradient towards the extraction well, the groundwater
. recovery system prevented offsite migration of contaminants. Groundwater at the Site"was being re~ediated by the selected remedy and by natur~1 attenuation. Currently,groundwater at the Site is being remediated by enhanced bioremediation, whichaccelerates the attenuation of contaminant levels to well above natural attenuation. Whilethe enhanced bioremediation system is being implemented, migration of contaminants tonearby offsite areas is possible. The extent of possible migration of contaminants is ""believed to be relatively small for the anticipated duration of the shutdown and is beingmonitored. No domestic or other wells in the affected area are currently being used."
As summarized in Section 6 of this report and as reflected in the cun-ent Protectiveness Statement, the soiland groundwater remedies at the THAN Site are considered protective of human health and theenvironment and, although offsite groundwater migration of site contaminants is possible, data to date donot show this to be the case. Nevertheless, groundwater at the Site will continue to be monitored.

6. FIVE-YEAR REVIEW FINDINGS
6.1 Fivc-Year Rcvi.c·w Pr,uccss
The THAN Site Five-Year Review was led by Brian Farrier, EPA Remedial Project Manager for theTHAN Site. A kick-off meeting fophe Five-Year Review was held on February 7,2007 at EPA officesin Atlanta. The Five-Year Review consisted of the following activities: document review, limited datareview, a Site inspection, and community interviews. As appropriate, various recent documents and theassociated data were reviewed as part of this five year review. These documents included the RemedialAction Construction Report for QU-2 (September 2002) and the Remedial Action Report for QU-2(September 2004), which address the'soil and sediment remedy, as well as the Work Plan for EnhancedBioremediation of' Groundwater (September 200 I) and the two reports addressing the EnhancedBioremediation Evaluation of Groundwater (HRC Injection, Decem~er 2003, and EHC Injection, July2007). Discussions regarding the Site inspection, community interviews, and public notification areprovided below.
6.2 Cornmunity N()tifical.ion and Involvement
Notification to the general public regarding the availability of the draft review report was completed bythe USEPA via the publication of a newspaper announcement. The announcement was published in thelocal newspaper, The Montgomery Advertiser, on September 3, 2007. A copy of the announcement isincluded in Attachment H. In addition, a notice will be published by the EPA when the review process iscompleted.
Interviews of local residents were also completed as part of the review process. Additional discussionregarding the interviews is provided below in Section 6.3.
Further, an article discussing the status of the Site was published in The Montgomery Advertiser onApril 11, 2005. A copy of that article is also included in Attachment H. In general, the article providedfavorable information pertaining to the Site.
6.3 Site Inspection and IIlICrviL'\\'S

Mr. Bob Barnwell with ADEM and Mr. Ben Reeves who performs O&M work at the Site also met withSite representatives to provide input.
The purpose of the Site inspection was to observe the general condition of equipment, monitoring andextraction wells, the vegetative cover over the soil and sediment treatment area, and Site security andfencing.
In general, the Site was in good condition. Fencing around the two properties was intact and the locks onthe gates were operable. Although there had been past acts of vandalism at the Site, there were no signsof recent activity at the Site with the exception of evidence that trespassers had entered one of thebuildings to remove copper wiring. Based on past groundwater monitoring activities, the monitoringwells were thought to be in good operating condition and, therefore, these were not inspected at this time.However, the vaults for the groundwater extraction system were observed and appeared to be in goodcondition. Additional information regarding the site inspection is provided in the completed SiteInspection Checklist (Attachment E).
Interviews with the local representatives familiar with the Site were conducted on May 14 and May 15.The interviews were conducted by Mr. Farrier with the assistance of Mssrs. Slater and Showers.Summary information regarding these activities is provided in Attachment D.
6.4 Risk Information Review
The following applicable or relevant and appropriate requirements (ARARs) were identified in the RODand initial Five-Year Review and were reviewed as part of this Second Five-Year Review:
• Comprehensive Environmental Response, Compensation and Liability Act (CERCLA)
• Resource Conservation and Recovery Act (RCRA)
• Occupational Safety and Health Administration (OSHA)
• Federal Maximum Contaminant Levels (MCLs) under the Safe Drinking Water Act
• Performance standards for soil and sediment based on human-health risk under industrial scenario
The MCLs for pesticides and VOC groundwater constituents, as well as the performance standards forsoil and sediment, are indicated in Attachment C.
One MCL has been revised since completion of the First Five Year Review. The MCL for arsenic wasreduced to 10 J.lg/L (ppb). However, while arsenic is a constituent of concern in soil and sediment, it isnot for groundwater. In fact, during the RI, slow purge sampling data indicated that arsenic was notdetected in samples above the detection limit of 5 fJg/L.

6.5 Data Review
6.5.1 Groundwater
Historical data from the THAN Site show that the distribution and mass of VOCs in groundwater havedecreased substantially as a result of natural attenuation. Pesticides, as expected, have attenuated at lowerrates than the VOCs; however, the concentrations of these constituents barely exceed the performancestandards and the pesticide plumes are not migrating. Following the operation of the GWRS, Arkemasubmitted a Work Plan for Enhanced Bioremediation of Groundwater based upon asymptotic levelsobserved and pursuant to Section IV. B Task III of the SOW for OU-2. The Work Plan was submitted asan Addendum to the Final Design Submittal for the Interim Remedial Action (OU-1) for EPA approval.
The effectiveness of enhanced biodegradation was evaluated by injecting HRC™ and monitoringgroundwater quality within a defined treatment area (see Figure 4). The selected treatment area wasapproximately 150-feet wide by 240-feet long throughout a 25-foot vertical interval from approximately15-feet bgs to 40-feet bgs. HRC™ injection locations were spaced on an approximately 15-foot grid withadjacent rows offset at the mid-point of the previous row (refer to Figure 5).
The amount of HRC™ injected at each location was proportional to the estimated concentrations ofchlorinated ethenes, primarily CT and TCE, in each area. The amount was based on stoichiometry of thereactions and included a safety factor to account for potentially uneven distribution, variations in CT andTCE concentrations, and competitive reactions. The stoichiometric analysis estimated that approximately0.5 pounds per foot of HRC™ was required to degrade the contaminant mass in shallow groundwater.Based on the manufacturer's recommendations, a minimum of 2 pounds per foot was selected for theHRC™ injection.
The HRC™ injection resulted in an increased production of TCE degradation productscis-l,2-Dichloroethene (cis-l,2-DCE) and ethane, and the CT degradation product chloroform. Vinylchloride, the last constituent in the degradation chain before ethane, has not historically been detected atthe Site. The increase in detectable degradation product concentrations appears to be the result of theHRC™ treatment. Additionally, the HRC™ treatment resulted in the reduction of electron receptors,which is conducive to promoting reductive dechlorination. It should also be noted that geochemicalconditions of the impacted area were conducive to reductive dechlorination. Though these key reductivedechlorination elements were favorably enhanced as a result of the treatment, the concentrations of theparent products were not significantly reduced by the end of the monitoring period. The results of theseefforts are summarized and discussed in a report entitled, Enhanced Bioremediation Evaluation ofGroundwater (December 2003). Summary analytical data for natural attenuation parameters, pesticides,and VOCs in the study area are included in Attachment C.
Following the HRC™ injection and monitoring, further enhanced biodegradation was evaluated byinjecting EHC™ and monitoring groundwater quality within a defined treatment area (see Figure 6). Theselected treatment area was approximately 150-feet wide by 240-feet long throughout a 25-foot verticalinterval from approximately 15-feet bgs to 40-feet bgs. EHC™ injection locations were similar to theHRC™ locations where the injection points were spaced on an approximately 15-foot grid with adjacentrows off set at the mid-point of the previous row.
The amount of EHC™ injected at each location was proportional to the estimated concentrations ofchlorinated ethenes, primarily CT and TCE, in each area. The amount was based on column studies ofthe reactions and included a safety factor to account for potentially uneven distribution, variations in CTand TCE concentrations, and competitive reactions. The column studies estimated that approximately340 pounds of EHC™ per boring was required to degrade the contaminant mass in shallow groundwater.
6-3
6: Five-Year Review Findings Second Five-Year Review Report
The EHCTM injection resulted in significant reductions in TCE, CT, and their daughter products toconcentrations that are generally below the Site performance standard. Vinyl chloride, the last constituentin the degradation chain before ethane, has not historically been detected at the Site. Additionally, theEHCTM treatment resulted in the production of electron donors and the reduction of electron receptors,which continues to provide conditions that strongly promote reductive dechlorination. It should also benoted that geochemical conditions of the impacted area continue to provide conditions conducive toreductive dechlorination. Currently, the Site VOC concentrations in the area monitored have beenreduced such that there are no VOC concentrations that exceed a Site performance standard at the POC.The one minor exception is the concentration of I, I-DCE in monitoring well MW-27s. The 2005 and2006 data show concentrations above the performance standard of 7.0 IlgIL. However, note that CTconcentrations historically were highest in. this same well, but that these have been undetected since 2003.Since I, I-DCE is a breakdown product of CT, it can be expected that the recent concentrations ofI,I-DCE will continue to decline to below the performance standard. In addition, concentrations ofI, I-DCE in downgradient monitoring wells MW-28s and MW-62s indicate performance standards havebeen met at the POe. Summary analytical data for natural attenuation parameters, pesticides, and VOCsin the study area are included in Attachment e.
Additionally, pesticide concentrations were significantly reduced for all pesticides except for dieldrin andare below the Site performance standards (refer to Figure 7). Even though dieldrin persists, the remainingconcentrations are low and should see additional reductions with continued treatment by the residualEHCTM. Additionally, now that VOC concentrations have been reduced to below performance standards,the potential for co-solvency effect related to pesticide transport no longer exists. Therefore, theremaining pesticides are not likely to migrate more that a few feet due their high adsorption capacity tothe Site soils. The results of the EHC injection activities are summarized and discussed in a reportentitled, Enhanced Bioremediation Evaluation of Groundwater, EHC Injection Summary Report(July 2007), which is currently being reviewed by the agencies. Please note that during theDecember 2005 sampling event, groundwater samples were split with both the USEPA and ADEM.
6.5.2 Soil and Sediment
During baseline and interim performance monitoring events for the soil and sediment RA, samples weresubmitted to various laboratories for analysis for Site COCs. Brown and Caldwell (BC) collectedsamples during the events listed above and transported the samples to ELAB of Tennessee. This is thesame laboratory that performed the Site analytical work during the RI and subsequent evaluations.Analyses were performed using CLP protocol. Adventus performed its own analyses on samples splitwith Be. including more frequent monitoring for pH, moisture, and redox potential. This information isaddressed in the Adventus interim reports. During the September 2003 sampling event, samples werealso split with the EPA for analysis by its laboratory in Athens, Georgia. The EPA analytical results aredocumented in a memorandum from Donald Hunter dated November 6,2003. Finally, during the last twosampling events (July and August 2004), samples were split with Severn Trent Laboratories (STL) toobtain further control using CLP protocol.
Analytical results from the various laboratories are summarized in a table in Attachment e. Due to theamount of interim analytical data, not all data collected during this treatment phase are summarized.Rather, only the post-treatment data (i.e., following the final treatment cycle for a given zone) from thevarious laboratories. along with the baseline sampling data for each zone, are presented. The originaldata. as well as the CLP data packages, are maintained in the project files. A brief discussion of the datais provided below.

6: Five-Year Review Findings Second Five-Year Review Report
Arsenic was only analyzed during the baseline sampling event and the first interim sampling event. All ofthe arsenic results from those events were below the performance standard. Therefore, arsenic was notincluded in the analysis of subsequent samples. This approach was agreed to by the EPA.
September 2003 sampling data from the Adventus and EPA laboratories suggested that performancestandards had been met for the COCs for all twelve zones after twelve treatment cYcles. However, datafrom ELAB suggested that not all zones had met performance standards. As an additional measure ofconservatism, Adventus performed three additional treatment cycles on six zones (2, 3, 5, 6, 9, and 12)and those six zones were resampled in July 2004. The July 2004 data from ELAB indicated that twozones - Zone 2 and Zone 5 - met performance standards. STL data for split samples confirmed that Zone2 met performance standards, and that Zones 3 and 9 also met standards. Based on this apparentdiscrepancy, samples from Zones 3, 6, 9, and 12 were reanalyzed by ELAB. The data from thatreanalysis indicated that Zones 3 and 12 still did not meet performance standards. As a result, Zones 3and 12 were resampled. This resampling effort was completed in August 2004. The ELAB dataindicated that only one sample (Zone 12) showed concentrations above one performance standard;specifically, the DDD result was slightly greater than the standard (169 milligrams per kilogram (mg/kg)vs. 132 mg/kg). However, the two split samples analyzed by STL indicated that performance standardswere met in both samples. In addition, Adventus data for Zone 12 in Septe,mber 2003 showedconcentrations for DDD of 129 mg/kg and 110 mglkg in a split sample. Finally, EPA laboratory datafrom September 2003 also confirmed that Zone 12 had met the performance standard with concentrationsof 87 mg/kg and 108 mg/kg in the split sample. Based on the data set as a whole, treatment wasdiscontinued and the Remedial Action report for soil and sediment was transmitted to the agencies inSeptember 2004. In March 2006, EPA and ADEM concurred that the soil and sediment remedy had beencompleted in accordance with the requirements of the ROD and the CD.

10. PROTECTIVENESS ST ATEMENT
The soil and groundwater remedies at the THAN Site are considered protective of human health and theenvironment. Currently, groundwater at the Site is being remediated by enhanced bioremediation, whichaccelerates the attenuation of contaminant levels beyond that expected with natural attenuation. Althoughoffsite groundwater migration of Site contaminants is possible, data to date do not show this to be the caseand groundwater at the Site will continue to be monitored. No domestic or other wells in the affected areaare currently being used.

X. OTHER REMEDIES
[[there are remedies applied at the site which ate not covered above, attach an inspection sheet describingthe physical nature and condition of any facility associated with the remedy An example would be soilvapor extraction
XI. OVERALL OBSERVAnONS
A. Implementation of the Remedy
Describe issues and observations relating to whether the remedy is effective and functioning as designed.Begin with a brief statement of what the remedy is to accomplish (i.e, to contain contaminant plume,minimize infiltration and gas emission, etc)
Soil and sediment were treated to minimize impact of constituent migration to surface water andgroundwater, and to reduce risk associated with direct contact Remedial action for soil and sedimentusing enhanced bioremediation was completed in September 2004. Performance Standards for soil andsediment were met.
Groundwater was beated to minimize impact of constituent migration outside the property boundary, andto reduce risk associated with potential direct contact. Enhanced bioremediation of groundwater wascompleted in March 2002 and again in June 2005 Most constituent concentrations have met MCLsGroundwater monitoring is ongoing.
B. Adequacy of O&M
Describe issues and observations related to the implementation and scope o[O&M procedures Inparticular, discuss their relationship to the current and long-term protectiveness of the remedy.
Currently, O&M at the Site includes inspections of fence, buildings, and grounds, and mowing of grassareas. Operating systems (i.e., the groundwater recovery system) are currently shUl down.
C. Early Indicators of Potential Remedy Problems
Describe issues and observations, such as unexpected changes in the cost or scope of O&M or a highfrequency of unscheduled repairs, that suggest that the protectiveness of the remedy may becompromised in the future.
There have been no unexpected O&M costs during the monitoring phase for the remedial actionsimplemented. The possible exception to this was costs associated with repairs due to vandalism at theSite.
D. Opportunities for Optimization
Describe possible opportunities for optimization in monitoring tasks or the operation of the remedy
Groundwater data will continue to be reviewed to assess whether Performance Standards have been met.Emerging technologies that can further accelerate the biodegradation process may also be evaluated.
