STATUS OF WORK:EPA continues to work to implement the water line project at the Durham Meadows Superfund Site. This update provides summary of the current activities at the Site. The two current activities are the installation of a series of monitoring wells and the procurement of a contractor to implement the water line project.

A well drilling program will be implemented in Durham in July and August 2018 to install a series of monitoring wells to provide a baseline for groundwater flow and contamination prior to the installation of the water line and the abandonment of the existing private wells in Durham. These wells are also intended to document the outer limit of groundwater contamination. A map with the approximate location of the wells is attached.

WHAT RESIDENTS SHOULD EXPECT:The former Merriam Manufacturing location on Main Street (Route 17) will be used as the staging area for the monitoring well program. The staging area will be fenced. A construction trailer, drilling equipment, and drilling waste will be stored within the fenced area.

A drill rig will spend about 1 week at each loca-tion to install an open borehole to provide access to the bedrock groundwater. Once the bore-holes are installed a series of investigations will be performed at each location. The investigations include: lowering instruments down each bore-hole to identify the location of fractures that may transmit water (downhole geophysics); collection and analysis of water from these fractures (packer

testing); installation of 1-4 monitoring wells in the open borehole to provide long-term monitoring locations to obtain water quality samples and assess groundwater flow directions. These investigations will extend into the Fall 2018 and should be completed by the end of 2018.

NEXT STEPS:The United States Army Corps of Engineers (USACE) issued the solicitation for the water line project on June 14, 2018. Once the solicitation period closes, USACE will evaluate and award a contract for the implementation of the water line project. The solicitation will only be available online. In order to download the solicitation, offerors must access the Federal Business Opportunities website (www.fbo.gov).
