Collegeville, PA water treatment
What's in Collegeville's water, who supplies it, and how to fix what you find, with sources. Check your ZIP for your utility's EPA records.
Your water in Collegeville
ZIP 19426 is split among several suppliers: North Penn Water Authority, Pennsylvania American Water (Royersford and Norristown systems), Collegeville-Trappe Joint Public Works, Audubon Water Company, and two small Aqua Pennsylvania systems[1]. Which one you're on changes what's in your water, so check your bill first.
The standout is PFAS. Collegeville-Trappe Joint Public Works, a groundwater system serving about 8,470 people, reported PFOA up to 235 ppt and PFOS up to 15 ppt in EPA's UCMR 5 sampling[2]. That is far above the 4.0 ppt federal limit that takes effect in 2029, and above Pennsylvania's 14 ppt PFOA limit[3][4]. Check the system's latest notices for treatment updates since that sampling.
Local issues to know
- PFAS on other local systems: Pennsylvania American Water's Royersford system reported PFOS up to 10.7 ppt and PFOA up to 9.1 ppt; North Penn reported PFOA up to 5.1 ppt[2]. See PFAS.
- Hardness: Pennsylvania American Water's Royersford system reported 136 mg/L as calcium carbonate, about 8.0 grains per gallon in its 2023 report[5]. The USGS calls 61–120 mg/L moderately hard and 121–180 mg/L hard[6]. See hard water and our hardness by town table.
- Radon: 14% of 1,041 USGS-sampled Pennsylvania wells exceeded 4,000 pCi/L[7].
Utility or well? ZIP 19426: about 21% of the land area lies outside mapped public water service areas[1]. Homes in those areas are likely on private wells, which no utility tests. If that's you, start with a free in-home test.
