Site Description

The Parkview Well site, located in Grand Island, Hall County, NE, consists of an aquifer contaminated with industrial chemicals, primarily chlorinated volatile organics. The Nebraska Health and Human Services Section identified the contamination in 1999 when doing routine sampling of the Grand Island public water supply system.

The site consists of two project areas. The first area involves actions to clean up the down-gradient portion of the contaminant plume. The interim actions for this area include extracting and treating the contaminant plume. Actions also include providing alternate water supplies and ground water use controls for the entire plume. The second project area involves addressing the identified source area and remaining ground water contamination. Actions for the second area consist of in situ chemical oxidation, restrictions on use of the source area property, and periodic vapor intrusion monitoring.

Current Site Status and Cleanup Actions to Date

  • EPA conducted short-term cleanup actions in 2004 and 2005 to provide alternate water supplies to owners of affected domestic wells.
  • In 2006, EPA selected an interim remedy for the site in a Record of Decision (ROD) to address the down-gradient part of the ground water contamination plume.
  • EPA conducted a short-term cleanup action in 2007 to address the most highly contaminated soils in the source area.
  • In 2007, EPA selected the final remedy for the site to address the source area and remaining ground water contamination not addressed by the interim remedy.
  • In 2008, EPA completed the design for the interim remedy, including installation of ground water extraction wells, and started the design for the final remedy.

Current Funding Status

  • In Fiscal Year 2008, EPA obligated approximately $400,000 for the start of the cleanup action to extract and treat the down-gradient portion of the contaminant plume.
  • To date, EPA has obligated total of approximately $794,000 for cleanup activities at this site.
