dse conducted Phase I ESAs modified to include Phase II ESA soil sampling and analysis at four sites located in Albuquerque and Sheep Springs, New Mexico, Texarkana, Arkansas, and Rocksprings, Texas for the FAA. Based on prior experience, the FAA determined that significant levels of hydrocarbon constituents, metals, and/or PCB contamination in the soil could have resulted from previous practices.
These Phase II ESAs included soil sampling and analysis. Samples were collected at various locations at each of the sites and analyzed for petroleum contamination, volatile and semi-volatile hydrocarbons, polychlorinated biphenyls, and characteristic hazardous waste metals. The sample analyses were conducted by a laboratory utilizing USEPA approved analytical methods.
dse developed an Quality Assurance Plan that provided the minimum requirements for the chemical analysis of the environmental samples for the project. The plan was designed to: (1) monitor the performance of the measurement systems to maintain statistical control and provide rapid feedback so that corrective measures could be taken before data quality was compromised and; (2) verify that reported data were sufficiently complete, comparable, representative, unbiased and precise so as to be suitable for the intended use.
