Montgomery County water treatment
Water treatment for King of Prussia, Norristown, Collegeville, Royersford & Lansdale: utility PFAS and lead records, well issues, and a free water analysis.
Where Montgomery County's water comes from
Most of Montgomery County is on public water from Aqua Pennsylvania, Pennsylvania American Water, North Wales and North Penn water authorities, and smaller local systems, with private wells in the more rural north and west[1].
Key issues
- PFAS: EPA UCMR 5 results for some local systems were well above the 4.0 ppt federal limit that takes effect in 2029. Collegeville-Trappe Joint Public Works reported PFOA up to 235 ppt[2][3].
- Radon in wells: 14% of USGS-sampled Pennsylvania wells exceeded 4,000 pCi/L[4].
- Hardness: varies by utility; check your utility's annual report (CCR) for your number[5].
