【 摘 要 】

The purpose of this report is to provide a comprehensive summary of the distribution and trends of volatile organic compound concentrations near USDOE’s Horn Rapids Landfill (HRL). This report focuses mainly on the TCE plume monitored in the top of the unconfined aquifer near the HRL, but also addresses potential breakdown products of TCE. TCE concentrations in deep portions of the unconfined aquifer and the underlying confined aquifer are discussed to show the vertical extent of contamination. This report incorporates TCE data from offsite wells at the AREVA facility south of the Hanford Site. Discussion of TCE in groundwater in the 300 Area is included to differentiate between contaminant plumes and their sources in the 300 Area and near the HRL. Chromium monitoring results from a specific well downgradient of the 1171 Building is also included.
