Superfund Record of Decision (EPA Region 7): Hastings Ground Water Contamination, FAR-MAR-CO, NE. Hastings, Nebraska. (First Remedial Action), September 1988

摘要

The FAR-MAR-CO subsite of the Hastings Ground Water Contamination site is located east of the City of Hastings, Adams County, Nebraska. The site is currently owned by Farmland Industries, Inc., who acquired the property through a merger with FAR-MAR-CO, Inc. in 1967. The current and previous owners used various chemicals onsite for fumigation of stored grain. Contamination was discovered when complaints about water quality. Contaminated soil at the subsite are believed to be the result of accidental spills and may be the direct result of a 1959 grain dust explosion which damaged a fumigation tank system, releasing 997 gallons of fumigant. The selected remedial action for this site includes: in situ soil vapor extraction, utilizing vacuum extraction technologies; treatment of extracted vapor with an activated carbon system, and air and ground water monitoring.
