Cities ranked by the records
Ranked by the Purity Score of each city's main water system, highest first. Scores belong to water systems; there is no county score. The score is computed only from contaminants measured in the published EPA record, so this ranks the record, not which city's water is safest. How the score works.
0of 3 cities above the 15 µg/L action level
Based on each system's 90th-percentile result. Lead from household plumbing isn't in this record.

Frequently asked
How does Orange County tap water compare across cities?
PurityMap ranks 3 cities in Orange County by the Purity Score of each city's main water system, computed only from contaminants measured in the published EPA record. Scores belong to water systems, not to cities. The highest published score is Middletown's main water system: MIDDLETOWN CITY · PWSID NY3503534 · Purity Score 99 (Excellent) · Confidence: moderate · Assessed at the water-system level. The ranking compares the records, not which city's water is safest, and your own tap can differ with household plumbing.
How many Orange County cities had a PFAS sample above a 2024 EPA limit?
1 of 3 Orange County city reports had a PFAS sample above a 2024 EPA limit in EPA's UCMR 5 testing, including Monroe (PFOA 10.5 ng/L). That limit is judged on a yearly average, and water systems have until 2029 to meet it, so a single sample is not a violation. PFAS were detected at any level in 1.
Is there lead in Orange County tap water?
Utilities report lead as a 90th-percentile result from home taps. 3 of 3 Orange County cities reported a value above zero, and none was above the 15 µg/L federal action level. Lead usually comes from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
