What NILES CITY PWS customers can do
NILES CITY PWS's water exceeds federal PFAS limits. We recommend customers take action:
- Install a reverse osmosis (RO) or activated-carbon water filter certified to NSF/ANSI Standard 53 or 58 for PFAS reduction. RO systems remove the widest range of PFAS compounds.
- Do NOT boil your water to remove PFAS. Boiling concentrates them.
- Request your most recent Consumer Confidence Report from your utility and ask when PFAS treatment will be installed.
- Contact your local elected officials and water utility board to demand a remediation timeline.
- Get independent water testing through services like Tap Score (mytapscore.com) if you want to verify your in-home levels.
- Talk to your healthcare provider about PFAS exposure, especially if you are pregnant, nursing, or have young children.
