| Description | The Washington State Department of Ecology collected samples from the Yakima Railroad Area (YRRA) during April and October 2024 as part of an ongoing semi-annual sampling program. The YRRA is located along a railroad corridor which covers approximately six-square-miles in the cities of Yakima and Union Gap. Groundwater in the YRRA is impacted by tetrachloroethene (PCE) contamination from multiple sources. Cleanup activities in the project area began in 1991, and sampling results indicate effective reduction in PCE concentrations at select source area sites. Of the 38 wells sampled in 2024, 17 had PCE concentrations higher than (not meeting) the Model Toxics Control Act cleanup level of 5 µg/L. PCE concentrations exceeding (greater than) the cleanup level within the YRRA ranged from 5.18 µg/L to 18,200 µg/L. The 2024 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. |
