Technical Support for Reduction of Methylene Chloride Contamination in PaintStripping Rinse Waters at Letterkenny Army Depot

摘要

In response to a request for technical assistance from the Letterkenny Army Depot(LEAD), the USAEC initiated an evaluation of potential options for treatment of methylene chloride contamination present in paint stripping rinse waters. Site visits were conducted and potentially applicable technologies were identified. Air sparging was recommended for further evaluation. A Test Plan was prepared for the characterization of rinse waters. A Health and Safety Plan was also completed. Prior to implementation of these plans, LEAD engineers identified and successfully implemented an alternate, non-methylene chloride based paint stripper. This process modification negated the need for evaluation of methylene chloride treatment options. This report documents the efforts conducted prior to the process change to identify and evaluate control options. jg p4.
