Trichloroethylene (TCE) is defined as a Priority Pollutant covered under the Clean Water Act. The chemical is an organic vapor, and is a component used in degreasing, distillation, and painting operations (Woodside, 1999). Trichloroethylene is a liquid used as a solvent, and in other compounds (Environmental Protection Agency, 2011). Annually 10 million pounds of Trichloroethylene is used to manufacture Polyvinyl Chloride (PVC) (Gilbert & Heuvel, 2014). While current figures are not available, the EPA put US production of Trichloroethylene in 1991 at 321 million pounds (Environmental Protection Agency, 2012). When released into the air Trichloroethylene has a 7-day half-life. Trichloroethylene is slow to evaporate from subsurface soil,

Trichloroethylene can also enter groundwater, and migrate either to drinking water or into the air by vapor intrusion (Agency for Toxic Substances and Disease Registry, 2015). In the early 1980’s Trichloroethylene was one of the chemicals used in the 328X2 career-field (Davis, 2015). The chemical was used to remove grease from high voltage cables prior to installing them. The work was often done in a partially confined space, which depending on weather conditions may or may not have included an open door for ventilation. An organization would have to be prepared to test for Trichloroethylene exposure in advance, since the chemical and its byproducts do not last long in a person’s blood or urine, and special equipment is required to detect it (Agency for Toxic Substances and Disease Registry, …show more content…
In addition the plan will identify other alternatives that were considered and justify why the alternate that is preferred was selected (Department of Defense, 2012). Once this is completed, the plan will be made available for public comment. All significant comments will be answered and summarized to become part of the documentation recording selection of an action (DD). Except in emergency removal actions the DD will be written before putting a response into action. All DDs will comply with a minimum of nine required documentation criteria identified in DoDM 4715.20. Additional documentation criteria are required if the action addresses a site which falls under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Remedial action will consist of; documenting a remedial action work plan (RAWP) explaining how remedial action will occur, and implementing the remedial action. Once a remedy is operating as determined by the remedial design it is categorized as a remedy in place. From this point, the remediation will be operated and monitored until the objectives of the selected alternative documented in the DD are reached (Department of Defense,
