Is Parsippany Tap Water Safe? 2026 Water Quality Report
Short answer: Two PFAS, PFOA and PFOS, are above their federal limits (2024 limits that water systems have until at least 2029 to meet); 3 more are detected with no federal limit, and everything else measured is within its reference or not detected. Parsippany-Troy Hills Water Department serves 50,400 residents.

Questions
Frequently asked questions
Is Parsippany tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Parsippany, PFOA 10.9 ng/L and PFOS 9.3 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 4.2 µg/L against the 15 µg/L action level. PARSIPPANY-TROY HILLS WATER DEPARTMENT (PWSID NJ1429001) has a Purity Score of 50/100 (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.
Who provides tap water in Parsippany?
PARSIPPANY-TROY HILLS WATER DEPARTMENT (PWS ID NJ1429001) is the public water system on record for Parsippany, New Jersey, serving about 50,400 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Parsippany get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Parsippany's water?
Yes. In EPA's UCMR 5 testing (2023-09-14 to 2024-10-15), PFOA was measured at 10.9 ng/L against a 4 ng/L federal limit and PFOS was measured at 9.3 ng/L against a 4 ng/L federal limit. PFBS (7 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (8.3 ng/L, below the 400,000 ng/L state limit) and PFHxS (8 ng/L, below the 10 ng/L federal limit) were also detected. PFBA (5.9 ng/L), PFHpA (3.2 ng/L) and PFPeA (6.9 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.
Is there lead in Parsippany's tap water?
PARSIPPANY-TROY HILLS WATER DEPARTMENT's most recent lead 90th-percentile result (2026) was 4.2 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.
What does the latest Parsippany water report show?
PurityMap's current record for Parsippany holds 31 findings: 2 above a reference, 4 detected within the reference, 3 detected with no limit and 22 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
