Load and Fill Area, Building 106 Pond

Long-term monitoring (LTM)
  • Untreated wastewater from the Building 106 cleaning process was pumped into the unlined Building 106 pond.
  • An interim measure in 2007 removed contaminated sediments from the pond and soil adjacent to the pond. The pond water was treated on the site and discharged to the Naval Support Activity Crane wastewater treatment plant. After removal of the pond, the excavation was filled with clean backfill.
  • Biennial LTM of groundwater and surface water began in 2014 and is ongoing.
  • Volatile organic compounds were detected in surface water above media cleanup standards for the first time during the May 2018 LTM event and confirmed during a subsequent event in August 2018.
  • Additional investigation in the area of the former pond is planned for 2019.
  • Land use controls prevent use of groundwater.
