From the 1950s through the 1980s, people living and working at Marine Corps Base Camp Lejeune in North Carolina drank water contaminated with industrial solvents, dry-cleaning chemicals, and benzene. The water came from two main supply wells. The contamination came from a nearby off-base dry cleaner, an on-base fuel storage leak, and waste disposal practices that were not unusual for the time. The chemicals included trichloroethylene (TCE), tetrachloroethylene (PCE), vinyl chloride, and benzene. These are all known or suspected human carcinogens.

For decades, the government said that it had no legal liability for the health problems caused by this water. The reason was a legal doctrine called sovereign immunity. This doctrine says you cannot sue the federal government without its permission. People sickened by the water could not hold the United States responsible in court. This wall of legal protection existed even though internal Marine Corps documents from the 1980s showed that base officials knew the water was dangerous and delayed telling residents. The government essentially argued that even if it acted negligently, there was no legal remedy available to the victims.

That changed in 2022. Congress passed the Camp Lejeune Justice Act. This law did two things. First, it explicitly waived sovereign immunity for claims arising from exposure to the contaminated water at Camp Lejeune. This meant that for the first time, victims could sue the federal government for negligence, medical expenses, pain and suffering, and other damages. Second, the law created a two-year window for filing these claims, closing in August 2024. The law did not create a new cause of action, it simply removed the barrier that prevented people from using existing negligence law.

The liability in these cases hinges on straightforward negligence principles. To win a negligence case, a plaintiff must prove four things. The government owed a duty of care. The government breached that duty. That breach directly caused an injury. The injury resulted in actual damages. In Camp Lejeune, the duty is clear. The government operated the base and provided housing and water to service members and their families. The breach is also documented. The government knew about the contamination, did not fix it in a timely manner, and did not warn people. The causation is the hardest part. Proving that a specific chemical caused a specific disease in a specific person requires medical and scientific evidence.

The government has fought these cases hard, mostly on the issue of causation. It argues that many health problems have multiple causes and that the plaintiff cannot rule out other factors like genetics, smoking, or other environmental exposures. The government relies on the fact that millions of people lived at Camp Lejeune and many have not gotten sick. However, epidemiological studies from the Agency for Toxic Substances and Disease Registry have linked the Camp Lejeune water to several specific conditions. These include kidney cancer, liver cancer, non-Hodgkin lymphoma, leukemia, bladder cancer, multiple myeloma, Parkinson’s disease, and birth defects like spina bifida.

The practical outcome of this law is that the federal government has accepted liability for the contaminated water at Camp Lejeune, but it still contests individual claims on the medical facts. The government set up a process for administrative claims and then litigation. It has paid out settlements to thousands of claimants. The cases have not all been easy wins for plaintiffs. Medical documentation is crucial. A person who lived at the base for a short time and later developed a common cancer faces a harder road than someone who lived there for ten years and developed a rare cancer strongly linked to the chemicals.

This situation illustrates a broader principle in environmental liability law. A party can be legally responsible for harm even if the contamination was standard practice at the time. Negligence does not require malicious intent. It only requires that a reasonable person in the same situation would have acted differently to prevent foreseeable harm. The government officers who did not test the water or warn residents may not have acted with malice. But they failed to meet the standard of care that a reasonable person would have exercised.

For other property owners, businesses, and municipalities, this case underscores the danger of delay. Once you know contamination exists, your duty to act is immediate. Hiding the problem or hoping it goes away almost always makes legal liability worse. The Camp Lejeune story is also a lesson in legislative power. When a legal doctrine like sovereign immunity blocks justice, the legislature can step in and change the rules. The liability was not created by a court. It was created by Congress.
