Summary of the water contamination situation at Camp Lejeune

  • 8 water treatment plants serving the base
    • Hadnot Point (HP)
      • Began operation in 1942
      • Areas served:
        • Mainside barracks
        • Hospital Point family housing
        • Family housing at Midway Park, Paradise Point, and Berkeley Manor until June 1972
      • Tarawa Terrace (TT)
        • Began operation in 1952
        • Shut down in March 1987
        • Areas served:
          • Tarawa Terrace family housing
          • Knox trailer park
          • Holcomb Boulevard (HB)
            • Began operation in June 1972
            • Areas served:
              • Family housing at Midway Park, Paradise Point, Berkeley Manor, and Watkins Village
              • Tarawa Terrace family housing after March 1987
              • Courthouse Bay
              • Rifle Range
              • Onslow Beach
              • Montford Point/Camp Johnson
              • New River
              • VOCs detected in HP and TT wells during 1980-85 sampling program
              • Samples collected by Camp Lejeune staff
              • Chemicals detected included TCE, PCE, benzene, DCE
              • Contamination of wells began many years before detection
              • Other on-base treatment plants were not contaminated
            • Contamination of HP and TT drinking water systems was intermittent
            • Wells rotated in and out of service
            • Each system had more wells than necessary to supply water on any given day
          • Tarawa Terrace Treatment Plant
          • PCE (perchloroethylene or tetrachloroethylene) was the main contaminant
          • Maximum level detected in drinking water was 215 parts per billion (ppb) in February 1985
          • Source of contamination was ABC One-Hour Cleaners, an off-base dry cleaning firm
          • The most contaminated wells were shut down in February 1985
          • ATSDR used water modeling to estimate past exposure levels
          • PCE concentration exceeded the current EPA maximum contaminant level of 5 ppb in drinking water for 346 months during November 1957-February 1987
          • Hadnot Point Treatment Plant
          • TCE (trichloroethylene) was the main contaminant
          • Maximum level detected in drinking water was 1,400 ppb in May 1982
            • The current limit for TCE in drinking water is 5 ppb
          • Other contaminants detected included PCE, DCE, vinyl chloride and benzene
          • Multiple sources of contamination
            • Leaking underground storage tanks
            • Waste disposal sites
          • The most contaminated wells were shut down by February 1985
          • ATSDR used water modeling to estimate past exposure levels
            • At least one VOC exceeded its current EPA maximum contaminant level in drinking water during August 1953 and January 1985

          • Holcomb Boulevard (HB) wells were generally not contaminated
          • Contaminated water from the Hadnot Point (HP) water treatment plant supplied the HB drinking-water system when the HB plant was shut down during January 27-Febraury 7, 1985
          • Contaminated water from HP water treatment plant was used intermittently to supplement the HB drinking-water supply during dry spring and summer months when demand was high
