An emergency environmental sampling survey was performed at Cibolo, TX on 21 Sep 90. The purpose of the survey was to sample, analyze, and determine the appropriate disposition of approximately 60 drums containing unknown materials. Sampling strategies were implemented in order to adequately and properly identify the contents of each drum. Each drum was either sampled individually or, when feasible, composited with another drum. The analyses prescribed for this project are designed to determine if the drums contain unused material, recycleable material, or waste product. The analyses will also determine if the waste products are hazardous or nonhazardous. The analytical methods used are presented in the table. The appropriate analysis for each drum was determined based upon visual inspection of the material through a disposable composite liquid waste sampler. Gas ChromatographMass Spectrometer chemical identification and hazardous waste characteristics analyses were performed on materials which appeared to be unused. Energy recovery analyses were performed on materials which appeared to be uncontaminated waste oil. Toxicity characteristic leachate procedure analyses were performed on all unknown wastes, unsegregated wastes i.e., waste oil and antifreeze, and paint and thinner wastes. A volatile organics screen was performed on some solvents that appeared to be uncontaminated.
