Their carbon-fluorine bonds make them extremely resistant to environmental degradation; they have contaminated drinking water, soil, and biological systems worldwide."},{"question":"What health conditions are linked to PFAS exposure?","answer":"Kidney cancer, testicular cancer, thyroid disease and thyroid cancer, liver damage, high cholesterol, ulcerative colitis, pregnancy-induced hypertension, immune suppression, and reproductive problems. The C8 Science Panel identified probable links between PFOA exposure and six specific conditions."},{"question":"Who can file a PFAS contamination lawsuit?","answer":"Individuals who lived, worked, or were stationed near contamination sources (military bases, industrial sites, airports) and developed linked conditions may file personal injury claims. Municipal water systems can claim cleanup and treatment costs; state attorneys general can pursue enforcement actions."},{"question":"What was the 3M PFAS settlement?","answer":"In 2023, 3M reached a settlement valued at approximately $10.3 billion over 13 years to resolve municipal water system claims. It addressed water treatment and remediation but did not resolve individual personal injury claims, which remain active."},{"question":"How do I know if my water is contaminated with PFAS?","answer":"Check the EPA's UCMR database, your state environmental agency's records, or the Environmental Working Group's PFAS contamination map. Living near a military base, airport, or industrial facility that used or manufactured PFAS elevates risk."},{"question":"What are the new EPA PFAS drinking water standards?","answer":"In 2024 the EPA finalized enforceable MCLs for six PFAS compounds: 4 ppt for PFOA and PFOS individually, plus a hazard index approach for four additional PFAS. Water systems must test for and treat PFAS contamination."},{"question":"How can my firm acquire PFAS case leads?","answer":"Geographically targeted digital marketing in known contamination areas, community outreach, partnerships with environmental advocacy organizations, referral networks, and specialized PFAS lead generation providers that pre-screen claimants by geographic exposure and diagnosed conditions."},{"question":"Is PFAS litigation related to AFFF firefighting foam lawsuits?","answer":"Yes. AFFF is a major source of PFAS contamination near military bases and airports. AFFF litigation is a subset of broader PFAS contamination litigation, consolidated in MDL No. 2873 in the District of South Carolina."}],"related":["afff-firefighting-foam-lawsuit","camp-lejeune-water-contamination-lawsuit","hair-relaxer-cancer-lawsuit","rideshare-accident-injury-claims"]}
