| Description | The Washington State Department of Ecology conducted four sampling events at the Yakima Railroad Area (YRRA) groundwater monitoring network between 2022 and 2023 as part of an ongoing semi-annual sampling program. The YRRA is located along a railroad corridor encompassing approximately six-square-miles in the cities of Yakima and Union Gap. Groundwater in the YRRA is impacted by tetrachloroethene (PCE) contamination, originating from multiple sources. Cleanup activities in the project area began following site definition in 1991, and sampling results indicate effective reductions in PCE concentrations at select source area sites. Of the 41 wells sampled in 2022 and 2023, 19 had PCE concentrations above (not meeting) the Model Toxics Control Act cleanup level of 5 µg/L. PCE concentrations above the cleanup level at individual sites within the YRRA ranged from 5.03 µg/L to 22,000J µg/L. The 2022 – 2023 groundwater data confirm continued impact from PCE and associated contaminants in groundwater throughout the YRRA project area. While concentrations have decreased at some identified source areas, high PCE concentrations remain in the central portion of the YRRA. |
