R7 ESO: Hastings Groundwater Site Colorado Ave. OU1 Technical Support Follow On

Background
The U.S. Environmental Protection Agency (EPA), Region 7, is responsible for overseeing the Hastings Groundwater Superfund Site located in Hastings, NE. The site has been on the National Priorities List since 1986 due to contamination from former industrial activities, particularly from Hastings Industries, which used Trichloroethene (TCE) in their operations.

The EPA's mission includes ongoing remedial activities to address environmental risks and protect public health. This justification outlines the need for continued groundwater sampling and analytical support at the Colorado Avenue Subsite, Operable Unit 01, as part of these efforts.

Work Details

1. Conducting groundwater sampling and analytical support at the Hastings Groundwater Contamination Site.
2. Repairing or abandoning damaged monitoring wells as identified by the EPA or EA during field activities.
3. Continuing work under contract 68HE0118D0004, task order 68HE0723F0025, which was previously established for groundwater sampling activities.
4. Addressing the newly identified need for monitoring well abandonment and installation.

Period of Performance
The period of performance is not explicitly stated but is implied to be ongoing as part of the current remedial activities at the site.

Place of Performance
The contract will be performed at the Hastings Groundwater Contamination Superfund Site located in Hastings, NE.
