Camp Lejeune Chemicals: TCE, PCE, Benzene, and Vinyl Chloride

Part of the Camp Lejeune Water Contamination investigation

The short answer

Four primary toxic chemicals contaminated Camp Lejeune's water supply at concentrations far exceeding EPA safety standards. Each chemical is linked to distinct cancer types and health effects, and understanding which chemical contaminated which water system helps establish the causal pathway between an individual's specific exposure and their specific diagnosis.

Trichloroethylene (TCE) — Hadnot Point's Primary Contaminant

TCE was the dominant contaminant at Hadnot Point water treatment plant, reaching concentrations up to 1,400 micrograms per liter — 280 times the EPA's current maximum contaminant level of 5 mcg/L. TCE was used extensively as a metal degreasing solvent in the base's industrial operations. The EPA, IARC, and the National Toxicology Program all classify TCE as a definite human carcinogen. TCE causes kidney cancer (through its genotoxic metabolite trichloroacetate), non-Hodgkin's lymphoma, leukemia, and liver cancer. TCE also damages dopaminergic neurons through mitochondrial complex I inhibition, producing Parkinson's disease — a mechanism confirmed in multiple animal and human epidemiological studies. TCE crosses the placental barrier, causing cardiac defects and other birth defects in children born to exposed mothers.

Perchloroethylene (PCE) — Tarawa Terrace Contamination Source

PCE contaminated the Tarawa Terrace water system primarily through leaching from ABC One-Hour Cleaners, an off-base dry cleaning facility located upgradient of the water supply wells. PCE concentrations reached 215 mcg/L — 43 times the EPA standard of 5 mcg/L. PCE is classified as a probable human carcinogen by the EPA and a definite carcinogen by IARC. It is linked to bladder cancer (through urinary excretion of its carcinogenic metabolites), non-Hodgkin's lymphoma, kidney cancer, and scleroderma. PCE is also suspected to have xenoestrogenic effects — disrupting estrogen signaling in ways that may explain the elevated male breast cancer rates observed by ATSDR.

Benzene — Leukemia and Blood Cancer Carcinogen

Benzene was detected in the Hadnot Point water supply from underground storage tank leaks and other industrial sources on base. The EPA states that there is no safe level of benzene exposure — it is a definite human carcinogen with a well-established mechanism. Benzene is metabolized in the bone marrow to reactive metabolites that damage hematopoietic stem cells, causing acute myelogenous leukemia (AML), chronic lymphocytic leukemia (CLL), chronic myelogenous leukemia (CML), multiple myeloma, and non-Hodgkin's lymphoma. ATSDR's analysis identified significantly elevated rates of these blood cancers specifically in areas served by the Hadnot Point system.

Vinyl Chloride — TCE Degradation Product

Vinyl chloride is produced by the anaerobic breakdown of TCE and PCE in groundwater and was detected in both the Hadnot Point and Tarawa Terrace systems. The EPA classifies vinyl chloride as a known human carcinogen. It is directly linked to hepatocellular carcinoma (liver cancer), angiosarcoma of the liver, and brain cancers. Vinyl chloride also increases the risk of lung cancer and lymphomas. The detection of vinyl chloride at Camp Lejeune strengthens the overall toxic soup argument — multiple synergistically acting carcinogens were present simultaneously, potentially amplifying the risk of any individual chemical beyond what epidemiological studies of single exposures would predict.

FAQ

Frequently Asked Questions

12 QUESTIONS

To qualify for a CLJA claim, you must have been physically present at Camp Lejeune, NC for at least 30 cumulative days between August 1, 1953 and December 31, 1987. Eligible individuals include: active duty servicemembers (primarily Marines and Navy personnel); their family members who lived on base (spouses, children, parents living in base housing); civilian employees of the Department of Defense stationed at Camp Lejeune; and contractors who worked on the base during that period. You must also have been diagnosed with a disease or condition linked to the contaminated water. Importantly, you must also have filed an administrative claim with the Navy JAG on or before August 10, 2024 — that deadline is now closed for new claimants. Veterans who did not file a CLJA claim may still pursue VA disability benefits separately.
