See the record ↓Worcester (T)'s drinking water received a grade of A- (86.3 out of 100), indicating good water quality. The city's 2 water systems serve approximately 899 residents using groundwater.
Lead levels were measured at 2.4 ppb (90th percentile), well within EPA limits. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 77 violations on record, including 1 health-based violation. 7 remain unresolved.
Worcester (T) ranks #397 out of 810 cities in New York for water quality, placing it mid-range in the state. Worcester (T) relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff. Hexavalent chromium (chromium-6) was detected at 0.03 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration. As a small community water system, Worcester (T) may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
02What's in Worcester (T)'s water
Every contaminant flagged in Worcester (T), on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.

| Contaminant | Detected Level | EPA Limit | Unit | Category | Status |
|---|---|---|---|---|---|
| Lead (90th percentile) LeadHeavy Metal A toxic heavy metal that can leach into drinking water from older pipes, solder, and fixtures. No amount of lead in water is considered safe. Health EffectsBrain and nervous system damage in children, kidney damage, high blood pressure, and reproductive problems in adults.

04Where Worcester (T)'s water comes from
Worcester (T)'s drinking water is drawn from underground aquifers through wells.
Groundwater
Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.
Local treatment
Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.
2 systems
2 water systems, operated under local government ownership.
899 people
Residents served across Worcester (T)'s service area.
Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals. Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds. The system is operated by local government ownership and serves approximately 899 people through 2 water systems.
