Fact Sheet

May 2010

Remedial Action for Parkview Well OU1, Parkview Well Superfund Site, Grand Island, Hall County, Nebraska


The U.S. Environmental Protection Agency (EPA) will begin the Remedial Action for Parkview Well Operable Unit 1 (OU1) in June 2010. The Remedial Action addresses ground water contaminated by hazardous substances migrating from the property at 3304 Engleman Road South in Grand Island, Nebraska. The contaminate plume contains dilute chlorinated solvents exceeding Safe Drinking Water Act maximum contaminant levels (MCLs) or Preliminary Remediation Goals (PRGs).

The Remedial Action will help restore contaminated ground water at OU1 to its beneficial uses by treating the water.  OU1 addresses private and municipal wells within the ground water plume and the eastern portion of the ground water plume near the Parkview subdivision. 


The Parkview Well site consists of an aquifer contaminated with industrial chemicals, primarily chlorinated volatile organics. Contamination at the site was originally discovered in 1999 during routine public water supply sampling by the Nebraska Department of Health. Two ground water contaminant plumes were identified in southwestern Grand Island.

Northern Plume
The Northern Plume has a former source area on the CNH America facility. CNH America, with oversight by the Nebraska Department of Environmental Quality, is addressing onsite soil and ground water contamination. Ground water migrating east from the property boundary of the CNH America facility does not exceed cleanup levels.

Southern Plume, OU1 and OU2
The ground water contamination extends approximately 3.5 miles from the Southern Plume source area (3304 Engleman Road South) into and beyond the Parkview subdivision.

The Southern Plume has been separated into two Operable Units (OUs) or areas targeted for distinct cleanup remedies. OU1 is the Interim Remedial Action that addresses ground water contamination within and near the Parkview Subdivision, and is designed to protect private and municipal wells near the plume's end. OU2 is the site-wide final Remedial Action that includes the Southern Plume source area and remaining ground water contamination not addressed by OU1.

Soil with the highest contamination at the 3304 Engleman Road South source area, was excavated during a removal action in 2006. The remaining saturated soils and ground water near and downgradient of the 3304 Engleman Road South property will be addressed by a Remedial Action for OU2, scheduled to start in May 2010.

In July 2006, EPA prepared a Proposed Plan for OU1 and held a public comment period for the plan. The Record of Decision was prepared in September 2006.  A public availability session was held in July 2009, to discuss the Remedial Design and the pending Remedial Action construction. The construction on the OU1 ground water treatment system began in August 2009.

Remedial Action Based on the Record of Decision for OU1

Cleanup/construction activities outlined in the Remedial Design and the Record of Decision include the following actions:

Contaminated ground water will be treated through extraction, air stripping, and discharge of treated water to the storm sewer system and beneficially reused in lake level stabilization.

Monitoring will be conducted to evaluate the performance of the remedy. Alternate water supplies such as whole-house treatment will be provided to those with an existing domestic well used as a primary drinking water source impacted with site contaminants above MCLs or PRGs. A connection to an existing water main will be provided to (1) those currently on whole-house treatment within the plume and with access to an existing water main or (2) any homes newly identified with site contaminants above MCLs or PRGs and with access to an existing water main. Note - Although EPA will provide alternate water supplies (whole-house treatment or water main connection), water district assessment fees will not be reimbursed for connections made to the existing water mains.

Institutional controls, such as ground water-use controls, will be placed within and/or near the area of ground water contamination.
