Description During 2021, the Department of Ecology conducted two rounds of ongoing semi-annual sampling of the Yakima Railroad Area (YRRA) groundwater monitoring network. The YRRA is a six-square-mile area located along the railroad corridor in the cities of Yakima and Union Gap. Groundwater within the project area is contaminated with tetrachloroethene (PCE).

Of the 40 wells sampled during 2021, 17 wells had PCE concentrations higher than (not meeting) the Model Toxics Control Act (MTCA) cleanup level of 5 ug/L. The maximum PCE concentrations ranged from 5.33 to 16,200 ug/L.

The elevated PCE concentrations primarily occurred in shallow wells at three of the source areas: Cameron Yakima, Washington Central Railroad, and Frank Wear Cleaners. Two of the shallow Remedial Investigation (RI) wells located along the western portion of the YRRA also had elevated PCE concentrations. The source of contamination for the RI wells has not been identified.
