Publication Summary

This document is one of a series describing the results of ground water sampling at Restover Truck Stop. Ecology has conducted ground water sampling at the site beginning in 1987 to the present. To remediate ground water contamination, a vapor extraction system was constructed in the summer of 1993. To determine the effectiveness of the cleanup, ground water monitoring has been expanded to quarterly sampling. This technical document describes the methods and results of sampling in July and November 1993.

Ground water sampling was the same as previous years; two water supply and five monitoring wells were sampled. All samples were analyzed for benzene, toluene, ethylbenzene, total xylenes (BTEX), and dissolved iron. BTEX concentrations have decreased substantially since 1990. Concentrations decreased slightly in some wells since January 1993, then increased slightly in November 1993. BTEX concentrations exceeded Model Toxic Control Act (MTCA) cleanup levels in some wells.
