| Short Description |
Soil gas and soil samples were collected as part of a preliminary Site Hazard Assessment on December 9-16, 1991, at the former Hytec fiberglass manufacturing facility in Tumwater, Washington. A total of 40 soil gas samples and 12 soil samples were collected and tested to provide information on the extent of on-site soil contamination and potential ground water contamination. This information will be used to score and rank the site using the Washington Ranking Method. (Also see abstract below) | |

| Abstract | Long Description |
Soil gas and soil samples were collected as part of a preliminary Site Hazard Assessment (SHA) on December 9-16, 1991, at the former Hytec fiberglass manufacturing facility in Tumwater, Washington. A total of 40 soil gas samples and 12 soil samples were collected and tested to provide information on the extent of on-site soil contamination and potential ground water contamination. This information will be used to score and rank the site using the Washington Ranking Method (WARM). Soil gas samples were analyzed in the field using a portable gas chromatograph. Trichloroethylene (TCE) was tentatively identified at 12 of 40 locations (30% detection frequency). Estimated TCE concentrations ranged from 1.8 to 53 ppb. The presence of TCE in soil gas samples suggests that ground water may be contaminated. Peaks for one or more organic compounds were recorded on the gas chromatograph but could not be identified. On May 19, 1992, two soil gas samples (air toxics samples) were collected and analyzed in the laboratory to verify field soil gas results. Field analyzed TCE detections were not confirmed with the air toxics samples. No correlation could be made between unknown peaks detected in the field soil gas samples and the air toxic samples. One soil sample, near the former tank site, showed elevated concentrations of acetone and ethylbenzene. Eleven priority pollutant semi-volatiles were detected in soil samples from the suspected spill area and the former tank area. Cobalt was elevated relative to background concentrations in one sample; and chromium appeared to be elevated in three samples. |
