Description Groundwater samples were collected semi-annually from 34 monitoring wells in the Yakima Railroad Area in 2014-2015. Data show the shallow groundwater throughout the project area continues to be contaminated with tetrachloroethene (PCE) that is attributed to numerous sources. Cleanup activities appear to have been effective in reducing contaminant concentrations at many of the identified sites. However, 16 of the sampled wells had PCE concentrations above the MTCA cleanup level of 5 ug/L. Maximum PCE concentrations ranged from 5 to 18 ug/L.

Twelve of the wells are located in the central portion of the project area and are screened in shallow and deeper portions of the aquifer. Elevated PCE concentrations in two deep wells indicate the contamination has a deeper vertical component in the central project area. The extent of the PCE contamination in portions of the YRRA need to be better defined. Groundwater sampling will continue to monitor PCE concentrations in the project area.
