Short answer: In the 2024–2025 records we hold for Muhlenberg Twp Muni, two PFAS, PFOA and PFOS, each had a sample above a 2024 EPA limit (not a violation: the limits are judged on a yearly average, due 2029), and a health-based violation is on record (EPA SDWIS). Also worth knowing: lithium sits above a screening level. 11 substances were detected and 20 were tested and not detected. The water is from Muhlenberg Twp Muni Auth, serving 22,400 residents.

Lead service lines
Muhlenberg Twp Muni Auth reported 107 galvanized service lines to replace in EPA’s inventory (2026Q2). Many utilities replace these lines for free or share the cost. Ask Muhlenberg Twp Muni Auth whether your home’s line is on its list before you pay anyone.
Local help
Call to be connected with a local plumbing provider about lead service lines, repiping or fixture replacement.
Older buildings may have lead service lines, solder or fixtures. Muhlenberg Twp Muni’s record shows lead at 1 µg/L (15 µg/L federal action level). Test first-draw water, then filter if needed.
9 of 29 PFAS tested were detected in Muhlenberg Twp Muni’s record (PFOS 11.5 ng/L, PFOA 8.8 ng/L and PFHxS 4.3 ng/L, and more); 2 above their limit. If PFAS matters to you, a filter certification names each compound it covers.
Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.
Your utility’s annual water quality report usually lists hardness; a test strip also measures it.
Reverse osmosis reduces many dissolved contaminants, including lead and minerals, at a single faucet, with some water sent to drain.

One email when a new sampling round is published, a result moves above or below its reference, or the system's score changes.PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Muhlenberg Twp Muni, PFOS 11.5 ng/L and PFOA 8.8 ng/L were measured in one EPA sample each, above the 4 ng/L limit EPA set in 2024 (not a violation: the limits are judged on a yearly average, due 2029); the lead 90th-percentile result was 1 µg/L against the 15 µg/L action level. MUHLENBERG TWP MUNI AUTH (PWSID PA3060038) has a Purity Score of 55/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap. What we found →

Yes. In EPA's UCMR 5 testing (2024-05-29 to 2024-12-20), PFOS was measured at 11.5 ng/L in one EPA sample, above the 4 ng/L limit EPA set in 2024 and PFOA was measured at 8.8 ng/L in one EPA sample, above the 4 ng/L limit EPA set in 2024. EPA's 2024 limits are judged on a yearly average, and water systems have until 2029 to meet them, so a single sample is not a violation. PFBS (5.2 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (15.6 ng/L, below the 400,000 ng/L state limit), PFHxS (4.3 ng/L, below the 10 ng/L federal limit) and PFNA (4.3 ng/L, below the 10 ng/L federal limit) were also detected. PFBA (6.6 ng/L), PFHpA (5.5 ng/L) and PFPeA (16 ng/L) were also detected; they have no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap. What we found →
MUHLENBERG TWP MUNI AUTH's most recent lead 90th-percentile result (2025) was 1 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink. Your household →
