Permanent biopile facility at twentynine palms MCAGCC

摘要

Battelle has designed, constructed, and operated a permanent bioremediation facility (biopile) at the Marine Corps Air Ground Combat Center (MCAGCC) in Twentynine Palms, California. The facility consists of a 46-meter-long by 26-meter-wide by 18-centimeter-thick concrete pad underlain with a 60-mil high-density polyethylene (HDPE) liner. The concrete pad contains 12 troughs that are approximately 17 meters long, 18 centimeters wide, and 28 centimeters deep, which contain the perforated extractionpipe. Prior to operation, a soil nutrient levels. Three rounds of sampling (initial, interim, and final) were conducted on the first 1,900 m~3 (2,500 yd~3) batch of petroleum hydrocarbon-contaminated soil treated at the facility. During treatment of the first batch of soil, Battelle used an On-Line Environmental Monitoring System (OEMS) to monitor oxygen, carbon dioxide, total petroleum hydrocarbon (TPH), and pressure for soil was used to monitor moisture content inside the soil pile and soil pile temperature measurements were obtained. Insights into the design, construction, and operation of permanent biopile facilities have been attained.
