City Dump (OU-3)

		The old New Haven City Dump (OU-3) resides on a 1.5 acre lot in the southeast part of New Haven. The dump is situated in a ravine on the north side of Highway 100 and is approximately 320 ft. wide by 200 feet deep. The north face of the dump is more than 35 ft high and debris including rusted metal 55-gallon drums are exposed near the toe of the slope. The surface of the dump has been covered with more than 5 feet of yard wastes and demolition debris. The ground-water monitoring network at the site consists of a single bedrock monitoring well (BW-03, 230 feet deep) on private land northwest of the site and several seeps located along the north face of the dump.

The remedial investigation of OU3 was completed by the USEPA in 2003. Trace concentrations of PCE (less than 2 micrograms per liter) have been detected in one seep and in the shallow (less than 100 feet deep) bedrock, however, no PCE has been detected in monitoring well BW-03. Hundreds of drums of industrial waste including dyes, and flammable solvents were reportedly placed in the dump before it was closed in the early 1970s. The U.S. EPA has sampled industrial wastes that were discovered on private land near the dump. Those wastes, thought to be similar to those placed in the dump, did not contained detectable concentrations of No PCE or other chlorinated solvents.
