Camp Lejeune, North Carolina:
Water Modeling - Summary |
|
|
Summary of the water modeling 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
- Water modeling conducted by ATSDR is complete
- PCE concentration exceeded the current limit of 5 ppb in drinking water at the TT water treatment plant 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 DCE (trans-1,2-dichloroethylene) at a maximum of 407 ppb in January 1985, PCE and benzene
- Multiple sources of contamination
- Leaking underground storage tanks
- Waste disposal sites
- The most contaminated wells were shut down by February 1985
- Water modeling is ongoing
- Presently unknown when contamination of some HP wells began, but may have begun as early as the late 1940s or early 1950s
- When the water modeling is completed by mid-2009, the dates when the system was contaminated will be determined
- Holcomb Boulevard wells were not contaminated
- Contaminated water from HP supplied the HB system when the HB plant was shut down for almost two weeks during January 27-Febraury 7, 1985
- Contaminated water from HP may have been used sporadically to supplement the HB supply during dry summer months when the golf courses were watered
