Superfund Record of Decision (EPA Region 7): Hastings Ground Water Contamination. Colorado Avenue, NE. Hastings, Nebraska (First Remedial Action), September 1988

摘要

The Colorado Avenue subsite of the Hastings Ground Water Contamination site is located in the City of Hastings, Adams County, Nebraska. From 1967 to May 1982 the site was used by Dravo Corporation for manufacturing of heating and air conditioning equipment. Metals were cleaned prior to finishing with a vapor-degreasing process, and the waste solvents were discharged directly into the sanitary sewer and the storm sewer. Ground water contamination was discovered when an out-of-service drinking water well was put back in service. 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.
