US HB3639

Veterans who served at military installations with PFAS-contaminated water become eligible for VA hospital care and medical services beginning 90 days after enactment, covering conditions linked to perfluorooctanoic acid exposure including diagnosed high cholesterol, ulcerative colitis, thyroid disease, testicular cancer, kidney cancer, and pregnancy-induced hypertension

Family members who resided at covered installations or were in utero during such residence qualify for the same VA healthcare benefits for PFAS-related conditions, with reimbursement available only after exhausting third-party insurance claims

Creates a presumption of service connection for disability compensation purposes, meaning veterans with listed conditions who served at PFAS-contaminated installations no longer need to prove their illness resulted from that service

Reserve component members who served at affected installations for a Secretary-specified period qualify for these benefits, with their service treated as active duty for eligibility purposes

Requires the VA Secretary to submit annual reports for three years to Congress detailing the number of veterans and family members receiving care, conditions treated, applications denied, and pending applications
