Health Assessment for Lindsay Manufacturing Company, Lindsay, Platte County, Nebraska, Region 7. CERCLIS No. NED068645696.

摘要

The Lindsay Manufacturing site is located in the village of Lindsay, in Platte County, Nebraska. An irrigation system manufacturing plant has operated at the site since 1958. Spent acid wastewater was discharged to an unlined surface impoundment from 1971 to 1983. Solvents were discharged into the surface impoundment, and also were dumped onto the ground. Soils and drainage ditch sediments are contaminated with heavy metals and volatile organic compounds (VOCs) on the Lindsay Manufacturing site. Ground water is contaminated on-site and off-site with heavy metals and VOCs. The plume of ground water contamination extends at least 2,250 feet south-southeast of the site. Since humans have been exposed to hazardous substances migrating from the site, but concentrations of those substances are below levels of public health concern for noncarcinogenic effects, and since levels of probable human carcinogens detected at human exposure points were very low, follow-up health activities are not being considered for the site at this time.
