The federal Agency for Toxic Substances & Disease Registry, a sister agency of the U.S. Centers for Disease Control and Prevention, is sending the survey to about 300,000 people who lived or worked at the Marine base and about 53,000 to those who lived and worked at Camp Pendleton, Calif., before 1986. The responses from Camp Pendleton are being used for comparison purposes, officials said.
The survey is the largest ever conducted by the agency, which has been conducting research about potential health hazards at the base. Officials say they hope it will answer long-standing questions about the health effects of exposure to contaminants at Camp Lejeune. The information is likely to have broader relevance outside the Marine base population because the chemicals in question are widely used in industry and “quite common groundwater pollutants worldwide,” said ATSDR Director Christopher Portier.
“If we get a good response, we have the potential to see what is happening in populations in ways that we have been unable to do so before,” he said. Previous studies about chemical exposure have generally involved much smaller populations.
“This study is so big and large that it stands the chance of clearing up a lot of those questions,” he said.
Those included in the survey are former active-duty Marines and sailors who were stationed at Camp Lejeune between June 1975 and December 1985, and civilian employees who worked at the base between December 1972 and December 1985. The survey is not being sent to everyone who ever lived at Camp Lejeune because the agency can’t identify them all from available records, officials said.
The 26-page survey asks about eight types of cancer — including brain, breast and lung — and 18 other diseases and conditions, including multiple sclerosis, Parkinson’s disease and miscarriages, that are thought to be related to exposure to contaminated well water. The water contained benzene, a known carcinogen, and tricholorethylene and tetracholorethylene, possible carcinogens.
Individuals will also be able to report other diseases not listed in the survey.
Benzene was in the base fuel tanks. The other pollutants were in solvents used to clean equipment on the base and in chemicals used by a dry cleaning plant outside the base, Portier said. The chemicals were dumped into storm drains and leaked from fuel tanks and seeped through the groundwater into the wells.
Concerns over tainted water at Camp Lejeune have been the subject of congressional hearings. The survey is in response to a congressional mandate. Officials and community groups hope the results will provide the federal government with information that could prevent future exposures.
