Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
lead 3.56 µg/L, below the 15 µg/L action level
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Screening: quick check, not lab-grade
Safe Home (EnviroTestKits)
Lead, read as one of three ranges: 0–4, 5–15 or 15+ ppb
What it can't tell you: It shows a lead range, not an exact level, and tests nothing else unless you pay extra for the optional lab test.
Lab-certified results
ETR Laboratories
50+ substances, including lead, copper, arsenic, nitrate, hardness and coliform bacteria
What it can't tell you: It does not test PFAS, and not every result on the panel falls under the lab's accredited scope.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Pompton Plains, no regulated PFAS were detected in EPA's 2024 testing; the lead 90th-percentile result was 3.56 µg/L against the 15 µg/L action level. PEQUANNOCK TWP WATER DEPARTMENT (PWSID NJ1431001) has a Purity Score of 93/100 (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.
PEQUANNOCK TWP WATER DEPARTMENT (PWS ID NJ1431001) is the public water system on record for Pompton Plains, New Jersey, serving about 14,010 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
None of the 29 PFAS in EPA's UCMR 5 testing (2024-01-02 to 2024-10-29) was detected. "Not detected" means below the lab's reporting limit, not proven zero.
PEQUANNOCK TWP WATER DEPARTMENT's most recent lead 90th-percentile result (2026) was 3.56 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.
PurityMap's current record for Pompton Plains holds 31 findings: 1 detected within the reference and 30 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
