Abstract : Personnel from the Armstrong Laboratory Water Quality Branch conducted Wastewater Characterization on the wastewater from a C-130 Engine Compressor Wash Operation at Little Rock AFB, Arkansas, 23-27 Jan 95. Based on the Cadmium and Nickel Mass Balance Models, the scope of the survey was to compare the models with the actual amount of cadmium and nickel in the engine compressor washwater from the point where the washwater fell from the C-130 aircraft to Little Rock AFB's wastewater discharge point. The combined results of the phased investigation led to our recommendations that the base could conduct compressor washes on up to two or three aircraft per day without pretreatment. We recommended that the base carefully monitor and maintain the oil/water separator at Facility 228 as long as compressor washes would be conducted there, to ensure that non-compliance would not result from cadmium in the separator from past operations being released into the sanitary sewer system in subsequent operations, resulting in a slug of heavy metals that could cause a violation of pretreatment agreement limits. Additionally, we recommended that if compressor washes were to be conducted for a long time period, the base should consider an industrial wastewater pretreatment system for heavy metals generated from the operations.
