Health Assessment for E. I. Dupont (County Road X-23), James Baier Farm Site,McCarl Farm Site, West Point, Lee County, Iowa. Region 7. CERCLIS No. IAD980685804

摘要

The E.I. DuPont (County Road X-23) Site was listed by the U.S. EnvironmentalProtection Agency (EPA) on the National Priorities List (NPL) in August 1990. The site includes two different locations at which contaminants are present, known as the McCarl Farm and James Baier Farm. A Preliminary Health Assessment for the James Baier Farm is discussed below. The Preliminary Health Assessment for the McCarl Farm is discussed under separate cover. The environmental pathways of potential public health concern are contaminated on-site and off-site ground water, contaminated on-site soils, and contaminated off-site surface water. The present state of contamination at the James Baier Farm poses a potential public health concern. Maximum concentrations of chromium, lead, and selenium found in ground water from on-site monitoring wells during 1986 and 1989 investigations are at levels that could pose marginal adverse health effects with long-term ingestion. Further environmental characterization and sampling of the site and impacted off-site areas during the Remedial Investigation should be designed to address the environmental and human exposure pathways discussed in the Preliminary Health Assessment and to further define the extent of contamination at the site.
