Upon examination, a corrosion hole in the water dump line was discovered. The impacted soil was excavated. Groundwater was encountered in the excavation at approximately 7 feet below ground surface. A groundwater sample (GW01) was collected from the open excavation and submitted for laboratory analysis of BTEX. Laboratory analytical results, recieved on February 9, 2016, indicated that benzene, toluene, and total xylene concentrations exceeded the CGWQS at 3,630, 6,090, and 3,200 µg/L, respectively. The analytical results and excavation details are summarized below.
