The Sandy Beach Road Ground Water Plume site consists of a TCE contaminated ground water plume approximately one-half mile wide by one mile long. The plume is present beneath residential areas within parts of Pelican Bay, Azle, and unincorporated areas of Tarrant County. The City of Pelican Bay supplies potable water to approximately 1,500 residents from ground water production wells. The water supply for Azle is from surface water and is unaffected by the contamination. The plume has affected three public water supply wells in Pelican Bay and as many as 12 residential drinking water wells in Azle, Tarrant County and Pelican Bay. Two of the municipal supply wells and nine of the residential wells had TCE concentrations above the accepted health-based level for TCE. The public water supply wells were shutdown and filtration units have been placed on the affected private water supply wells, or a public water supply line was extended to the home or business. EPA located a source area for the ground water contamination in the former dump site located on Mountain View Drive, north of Sandy Beach Road. Sample results from a passive soil gas survey provided data indicating past disposal of TCE along the eastern side of the former dump site. The attached figure illustrates the general location of the disposal activity. EPA completed a geophysical assessment in December to assess the approximate depth of the dump and presence of drums or other metal debris in the trichloroethylene “hot spotâ€. The geophysical report was finalized in February 2008, but the preliminary results did not identify the presence of drums or debris that warrants excavation at this time. EPA has completed residential water line connections to the City of Azle water supply system for those residences with contaminated private water supply wells within the City of Azle or in adjacent area of Tarrant County. Three additional residential water line connections to the City of Pelican Bay are pending amendments to the City water supply infrastructure, and still retain the filtration systems maintained by the TCEQ. A private irrigation well located southeast of the source area was tested by EPA and found to have a long screen interval that acts as a vertical conduit for migration of trichloroethene (TCE) from the Paluxy aquifer down to the top of the Twin Mountains aquifer. EPA completed installation of additional wells to evaluate the impact of the private well on the lower aquifer and completed sampling of the new wells. The groundwater analytical data determined that the private water supply well did not penetrate the productive section of the Twin Mountains aquifer, but TCE contamination is present beneath the site in the Twin Mountains aquifer.
