Data Summary Report for Area D Soil Gas Sampling and Analysis, McClellan Air Force Base. Volume 1. Data Summary
Abstract
CH2M HILL performed this work under a contract with McClellan Air Force Base for various environmental consulting services. The task order for which this report was prepared required sampling and analysis of soil gas extracted from vent risers through a low permeability cover over hazardous waste sites in Area D and from soil gas migration wells around the perimeter of the cover. The objectives of sampling and analyses were to provide data for comparison of the various sampling media used, determine the concentrations of target analytes in subsurface gases, evaluate the change in subsurface gas concentrations over time during vapor extraction, evaluate recovery of gas concentrations during non-extraction periods, evaluate sampling and analytical methods for future use in determining the nature and extent of contamination at the site, and recommended routine sampling and analytical protocols for soil gas monitoring at McClellan. This report is organized into a data interpretation volume (Volume I), and a second volume (Volume II) containing data both condensed and as received, and quality control reports.
