Abstract:

A wastewater characterization survey was conducted at Laughlin AFB, Del Rio, Texas, to provide the base with analytical data for the base National Pollutant Discharge Elimination System NPDES permit application. The analytical results from the wastewater survey showed excessive amounts of methylene chloride and chromium being discharged from the Corrosion Control Facility. Further, chromium and other heavy metals are accumulating in the sediment in the sewage lagoons. Effluent discharging off base contained small amounts of methylene chloride. Results of characteristics hazardous waste analyses showed the separator located outside the Corrosion Control Facility contains EP toxic hazardous waste. Recommendations 1 Laughlin AFB should submit an industrial discharger NPDES Permit application. 2 The corrosion control facility separator should be pumped out and the contents disposed of as hazardous waste. 3 Paint stripping practices at the corrosion control facility need to be changed. 4 The sewage treatment plant should be restored to treat base effluent prior to releasing to the sewage lagoons. 5 The base should test excavated material from previous lagoon deepening projects. 6 The base should establish a routine monitoring program to sample sediments at the bottom of lagoon No. 1.
