Yakima Railroad Area Groundwater Performance Monitoring

The Yakima Railroad Area covers approximately six square miles of predominantly industrial and commercial property adjacent to the railroad corridor in the cities of Yakima and Union Gap. In the 1980s tetrachloroethene (PCE) contaminated soils and groundwater was discovered at multiple facilities along the railroad corridor. Cleanup activities at several of these source areas has been implemented over the years.

The primary purpose of this monitoring is to evaluate the effectiveness of these cleanup actions at reducing the contaminant concentrations in the groundwater. The data may also be used to identify areas of contamination that require further action. Groundwater samples will continue to be collected semi-annually to monitor PCE concentrations in the project area. This work is conducted on the behalf of the Toxics Cleanup Program.
