Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
lead 10 µg/L, below the 15 µg/L action level (detected below the limit); 120,931 lead service lines; 3,266 galvanized lines to replace (context, not a tap measurement)
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

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 New York City, no regulated PFAS were detected in EPA's 2024 testing; the lead 90th-percentile result was 10 µg/L against the 15 µg/L action level. NEW YORK CITY SYSTEM (PWSID NY7003493) has a Purity Score of 74/100 (confidence: high), 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.
NEW YORK CITY SYSTEM (PWS ID NY7003493) is the public water system on record for New York City, New York, serving about 8,271,000 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 (2023-10-25 to 2025-01-02) was detected. "Not detected" means below the lab's reporting limit, not proven zero.
NEW YORK CITY SYSTEM's most recent lead 90th-percentile result (2024) was 10 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 New York City holds 37 findings: 7 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.
New York City's water is recorded as 1.9 gpg, soft. Hardness is an aesthetic and plumbing characteristic, not a health-based limit.

Methodology: how we analyze water. Prepared with AI assistance and reviewed by the PurityMap Editorial Team before publication.
Start with the hot-or-cold tap check. Where New York City System reported something related, it's shown below.
New York City disinfects with chlorine (utility water-quality report).
Lead at New York City System: 10 µg/L (90th percentile, 2024 monitoring period). Lead has no taste, so a taste neither shows nor rules it out.
Copper: 0.194 mg/L (utility water-quality report, 2025). The federal action level is 1.3 mg/L.
