Healthcare Water Quality Beyond Legionella
Hospital water safety programs have focused primarily on Legionella and opportunistic pathogens, but PFAS contamination of healthcare facility water systems raises additional patient safety concerns, particularly for immunocompromised patients and dialysis patients.
Dialysis and PFAS Risk
Hemodialysis patients have extensive blood contact with water-derived fluid during treatment. PFAS in dialysate water create direct blood exposure, bypassing gastrointestinal absorption barriers. Ultra-pure water requirements for dialysis should be evaluated for PFAS in addition to standard microbiological and chemical parameters.
Infant Formula Preparation in NICUs
Neonatal intensive care units prepare infant formula and medications with facility water. PFAS contamination of NICU water used for formula preparation directly exposes vulnerable neonates. NICU water quality programs should include PFAS monitoring as a standard of care.
Point-of-Use Treatment in Healthcare
Hospitals in PFAS-contaminated communities are deploying point-of-use RO systems for sensitive applications including dialysis, NICU formula preparation, and immunocompromised patient drinking water. Facility water safety plans should address PFAS as a chemical hazard alongside microbial risks.
