Site Summary

The former Ken Foster Farm is a 40-acre site in southeast Sherwood where waste from the nearby Frontier Leather Company tannery was applied to the ground surface in the 1960s and early 1970s. The site was farm and pasture land for many years, but has more recently been developed for residential housing. In 2006 EPA conducted a site inspection sampling investigation that found elevated concentrations of chromium, lead, and manganese on the site. In July 2007, DEQ completed a Screening Level Human Health Risk Assessment using EPA’s site data. At that time, DEQ concluded that metals in soil, including chromium, posed no unacceptable human health risk. However, in November 2011, DEQ updated its risk-based concentrations for hexavalent chromium based on new EPA toxicity data.

DEQ conducted a remedial investigation in fall 2013 that included soil and groundwater sampling to assess the magnitude and extent of hexavalent chromium. Hexavalent chromium was found to be fairly widespread in site soil above screening levels for human health. The Remedial Investigation Report containing an updated risk assessment will be completed in March 2014. DEQ will then identify appropriate actions to protect human health and the environment.
