| Short Description |
This document is one in a series describing the results of groundwater and surface water monitoring at the American Crossarm and Conduit site. Groundwater and surface water downgradient of the facility are being monitored to determine if the selected remedy of off-site disposal and containment of contaminated soil and sediment from the facility property has been an effective form of remediation. Ecology has conducted twice yearly monitoring at this site since 1997. (Also see abstract below) | |||

| Abstract | Long Description |
This document is one in a series describing the results of groundwater and surface water monitoring at the American Crossarm and Conduit site. Groundwater and surface water downgradient of the facility are being monitored to determine if the selected remedy of off-site disposal and containment of contaminated soil and sediment from the facility property has been an effective form of remediation. Ecology has conducted twice yearly monitoring at this site since 1997. Results of samples collected in November 2000 and April 2001 from two downgradient wells (MW-25 and MW-26) and two on-site surface water stations (ACCSW1 and ACCSW2) are discussed. All samples collected were analyzed for polynuclear aromatic hydrocarbons (PAHs) and chlorinated phenolics. In both sampling periods, naphthalene, 2-methylnaphthalene, and 1-methylnaphthalene were the primary PAHs detected in the downgradient monitoring wells. Mean concentrations were 0.028 ug/L for naphthalene, 0.027 ug/L for 2-methylnaphthalene, and 0.017 ug/L for 1-methylnaphthalene. None of the PAH constituents exceeded applicable standards. Chlorinated phenolics were not detected in either of the wells during these two rounds of sampling. Most of the PAHs analyzed for were detected at both surface water stations. Pentachlorophenol was tentatively identified at station ACCSW1 in September 1999 but has not been detected since. All detected analytes in the surface water samples were far below established water quality criteria for freshwater (EPA, 1992). |
