NASA, Kennedy Space Center, Florida. LC39A OMMR, 46 pp, 2016

This report presents the findings, observations, and results from Year 1 operation of the air sparging groundwater interim measure (IM) for high-concentration and low-concentration plumes within the perimeter fence line at Launch Complex 39A (LC39A). The objective of the LC39A groundwater IM is to actively decrease concentrations of TCE, cDCE, and VC in groundwater within the pad perimeter fence line via to levels less than Florida Department of Environmental Protection Groundwater Cleanup Target Levels. O&M information from system startup in February 2015 through December 31, 2015, is provided, plus performance monitoring results for quarterly groundwater sampling events through January 2016. From startup through the January 2016 groundwater sampling event, the air sparging system has met the performance criteria, achieving an overall 77% mass reduction of chemicals of concern. https://clu-in.org/download/techfocus/air-sparging/Sparging-ksc-2016.pdf
