Water Contamination Illnesses
Last updated: June 10, 2026
Different water contaminants are discussed in litigation alongside different illnesses. This page is organized by contaminant, so you can look up the substance allegedly found in a water supply, including PFAS, TCE and industrial solvents, benzene, and lead, and see which health conditions are most often raised in lawsuits involving that contaminant.
Looking for the broader case category? Explore Toxic Water Contamination Lawsuits, PFAS Water Contamination Lawsuits, and PFAS Drinking Water Contamination by State. For illnesses grouped by category across all exposure routes, including air, soil, and pesticides, see Environmental Contamination Illnesses.
This page provides general educational information about illnesses discussed in water contamination litigation and does not constitute medical or legal advice. A diagnosis discussed on this page does not mean a contaminant caused it, and litigation allegations are not proof of causation.
- Water contamination lawsuits tend to pair specific contaminants with specific diagnoses, so the contaminant involved usually shapes which illnesses are discussed.
- PFAS litigation most often involves kidney cancer, testicular cancer, thyroid disease, and ulcerative colitis.
- TCE and solvent claims often involve kidney cancer, non-Hodgkin lymphoma, and Parkinson's disease discussions, while benzene claims center on leukemia and other blood disorders.
- Residence history and water source records are usually the starting point for evaluating any water contamination claim.
How This Page Is Organized
Lawsuits involving contaminated drinking water rarely allege harm from "pollution" in the abstract. They usually identify a specific substance, a specific water source, and a specific diagnosis alleged to be associated with that substance. That is why this page is organized contaminant by contaminant rather than illness by illness.
If you already know your diagnosis and want to research it across all exposure types, start instead with Environmental Contamination Illnesses, Cancers Linked to Lawsuits, or Illnesses and Exposures Linked to Lawsuits.
PFAS and Firefighting Foam
PFAS chemicals, sometimes called forever chemicals, are the most active area of water contamination litigation today. Claims often involve public water systems near military bases, airports, firefighter training sites, and industrial facilities, as well as groundwater affected by AFFF firefighting foam.
Illnesses most often discussed in PFAS water litigation include:
- Kidney cancer
- Testicular cancer
- Thyroid disease and thyroid cancer
- Ulcerative colitis
- Liver-related concerns and elevated cholesterol in some scientific discussions

Check My EligibilityTCE and Industrial Solvents
Trichloroethylene, known as TCE, along with perchloroethylene and other chlorinated solvents, has been at the center of some of the most widely known water contamination litigation in the country, including claims involving Camp Lejeune. These solvents were historically used in degreasing, dry cleaning, and manufacturing, and have been alleged to migrate into groundwater near industrial sites.
Illnesses often discussed in TCE and solvent litigation include:
- Kidney cancer
- Non-Hodgkin lymphoma
- Parkinson's disease, a topic of growing scientific and legal discussion
- Liver cancer in some claims
- Certain birth outcome and developmental allegations

Benzene and Petroleum Contamination
Benzene can reach drinking water through leaking underground fuel storage tanks, refinery discharges, pipeline releases, and certain industrial operations. Benzene litigation has a long history, and in the water context it tends to involve a narrower and more consistent set of diagnoses than PFAS or solvent claims.
Illnesses most often discussed in benzene-related claims include:
- Acute myeloid leukemia
- Other leukemias and lymphomas
- Myelodysplastic syndromes
- Aplastic anemia and other blood disorders
Because these conditions involve the blood and bone marrow, diagnosis records and treatment history tend to carry significant weight in evaluating benzene allegations. See Diseases Linked to Chemical Exposure for how benzene fits into the broader chemical exposure picture.
Lead in Drinking Water
Lead typically enters drinking water through aging service lines, plumbing, and fixtures rather than through industrial discharge. Litigation in this area, including the widely covered municipal water cases of the past decade, has focused heavily on harm to children.
Topics most often discussed in lead-in-water litigation include:
- Developmental delays and cognitive harm in children
- Behavioral and learning concerns
- Kidney-related concerns with long-term exposure
- Pregnancy-related allegations in some claims
Families researching childhood exposure topics often continue to Developmental Injuries Linked to Lawsuits.
Other Contaminants People Research
Beyond the major litigation categories above, people researching water contamination also ask about arsenic in groundwater, nitrates from agricultural runoff, hexavalent chromium from industrial operations, and disinfection byproducts formed during water treatment. These substances appear in regulatory actions and scientific literature more often than in large-scale litigation, but they come up in individual and community claims from time to time.
For the legal framework these claims typically travel through, see Toxic Water Contamination Lawsuits and Environmental Contamination Lawsuits.
Records That Matter in Water Cases
Water contamination claims turn on a question most other exposure cases do not face: which water did you actually drink, and for how long. That makes residence history, water district and utility records, private well testing results, and public contamination notices the core documents in this area, alongside diagnosis and treatment records. Community-wide testing data and consent orders involving the alleged polluter can also matter.

Common Questions About Water Contamination Illnesses
Which contaminant is involved in most current water lawsuits?
PFAS chemicals, including those from AFFF firefighting foam, are the most active area of water contamination litigation today, most often alongside kidney cancer, testicular cancer, thyroid disease, and ulcerative colitis allegations.
Do all water contamination cases involve PFAS?
No. TCE and other solvents, benzene, lead, and other contaminants each have their own litigation history, and each tends to involve a different set of diagnoses.
Does having one of these diagnoses mean contaminated water caused it?
No. These illnesses have many possible causes, and the associations discussed in litigation are allegations, not established causation in any individual case. Exposure history, timing, and the scientific evidence for the specific contaminant all matter.
What should I gather before talking to a lawyer?
Residence history, the water source you relied on, any contamination notices you received, and your diagnosis records. The Do You Qualify for a Lawsuit? guide walks through the factors lawyers typically ask about first.
