1 DEPARTMENT OF THE ARMY US ARMY NSTALLATON MANAGEMENT COMMAND HEADQUARTERS, UNTED STATES ARMY GARRSON, FORT MCCOY SOUTH TH AVENUE FORT MCCOY, W November, 0 Ms. Mae Willkom Remediation and Redevelopment Program Wisconsin Department of Natural Resources P.O. Box 00 Eau Claire, Wisconsin 0-00 Dear Ms. Willkom: Fort McCoy collected a third round of perfluorinated chemicals (PFCs) at Fire Training Burn Pit (FTBP; BRRTS No. 0--) on August and, 0. Results for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) for September and December 0, and August 0 are summarized in Table. Analytical reports for September 0 are included in Attachment. The United States Environmental Protection Agency (USEPA) has established a Health Advisory (HA) level in drinking water for the concentration of PFOS + PFOA of 0 parts per trillion (ppt). Figure shows the location of FTBP, the monitoring wells present at the site, and the location of the nearest water body, Suukjak Sep Creek, more than,00 feet west (downgradient) of the former burn pit. As shown, there are monitoring wells that have been included in the monitoring program since 00. Based upon an agreement with the USEPA and the Wisconsin Department of Natural Resources (WDNR}, the other wells have not been monitored since 00. However, well OW (the farthest downgradient well, which has not been included in the monitoring program since 00) was sampled in August 0. lsoconcentration maps of combined PFOA + PFOS concentrations for each of the three sampling events are presented on Figures,, and. The data presented in Table and on Figures,, and show a good deal of fluctuation in concentrations at wells within the plume and at the downgradient plume margin. For six of the wells, the PFOS + PFOA concentrations were reported within the same order of magnitude during each of the sampling events. However, at four wells (OW, P0, P0A, and OW) reported concentrations fluctuated by an order of magnitude between sampling events. At well OW, located closest to former FTBP, reported concentrations fluctuated by two orders of magnitude during the three sampling events. Exceedances of the HA were reported at seven of the wells during December 0, when the average groundwater elevation across that site was the lowest between the three sampling events. HA exceedances were reported at five wells during August

2 0, when the average groundwater elevation was at its highest level for the three sampling rounds. HA exceedances were reported at six wells during September 0, when the average groundwater elevation across the site was between the December 0 and the August 0 level. The data show that the concentration of PFOS + PFOA at well OW, located just west of West Thirteenth Avenue, was above in December 0, and below the HA in September of 0 and August of 0. Well OW (the farthest downgradient well present at the site) was only sampled during August 0, and the reported concentration of PFOS + PFOA was below the HA. The data continue to show significant concentration fluctuations between sampling events for wells OW, OW0, and OW, located in the center of the groundwater plume flow path. Due to the fact that the level of concern (the HA) is 0 ppt, a very small fluctuation is significant. n most, if not all, groundwater plumes variability in concentrations between monitoring rounds at the same well can regularly be greater than 0 ppt, and often greater than 00 ppt. For most parameters, where the levels of concern (standards) are in parts per billion (ppb) or parts per million (ppm), a variation of 00 ppt (0. ppb/0.000 ppm) is written off as representing the actual concentration variability present within the plume at each location, or just noise in the data. Therefore, when the standard is in ppb or ppm, that amount of variability is not significant. However, when the level of concern is 0 ppt and the typical concentration variability within a plume can be at least times the concentration of concern, it complicates the process of defining the condition of the plume (stable, receding, expanding), along with the location of the downgradient plume margin. Data collected so far has confirmed that PFC concentrations near and downgradient of former FTBP are present at levels exceeding the HA (in some cases by several orders of magnitude), and that concentrations exceeding the HA are restricted to the water table wells, as exceedances have not been reported in the piezometers. However, not enough data has been collected to determine the condition of the plume (stable, receding, expanding), or to define the downgradient plume margin. n addition, insufficient data has been obtained to determine if reported concentration fluctuations, in wells located in the center of the plume flow path, are a result of actual concentration variability within the plume, or are being caused by ongoing releases from former FTBP. Other than the final remedial action conducted, which involved excavation and offsite disposal of 0 cubic yards of contaminated soil, it is not known if the ozone injection and bioremediation efforts implemented to remediate the chlorinated contamination did anything to reduce PFC concentrations at FTBP. Unlike petroleum constituents and chlorinated compounds, that have been investigated and remediated at many sites for more than three decades and are well understood, PFCs are emerging contaminants. Behavior of PFCs in the subsurface (migration/degradation) is not well understood, and methods of definition and remediation for these parameters are still being developed. As a result of evaluating sites that formerly used Aqueous Film Forming Foam (AFFF) for fire training, the Army

3 has identified PFC groundwater contamination at several installations across the country. Some of these Army installations have PFC contamination present in drinking water wells. To investigate and remediate these PFC contaminated sites and minimize human health risks, Army Headquarters is addressing this problem utilizing a nationwide contract, instead of having the work performed by each installation. This approach will ensure that taxpayer fund allocations are prioritized based upon human health risks present at each facility. Thus, the sites with contaminated drinking water wells will be addressed first. n addition to efficient allocation of taxpayer resources, this approach will ensure that PFC investigation and remediation knowledge gained along the way will be applied at subsequent facilities. The contractor is currently drafting the schedule to identify the timeline for addressing all Army installations with potential PFC impacts. The additional work required a FTBP will be conducted as part of the Army Headquarters nationwide contract. As Fort McCoy does not have contaminated drinking water wells, the additional investigation work at FTBP will benefit from lessons learned at Army installations with higher PFC risks. t is anticipated that the next phase of work at FTBP will begin in late 0 following work at the installations with greater PFC risks. f you have any questions, please contact Craig Bartholomew at (0) -.
