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. A better understanding of the extent of hexavalent chromium is needed to complete an updated risk assessment. Oregon DEQ is planning additional investigation in summer 2013. DEQ will use the Investigation results to complete a revised risk assessment and identify appropriate actions to protect human health and the environment.
