01The verdict: is Washington Twp.-1438 water safe?

Washington Twp.-1438's drinking water has significant quality concerns based on EPA testing data. With a grade of F (38/100), the system has issues across multiple categories. A water filter is recommended for all residents. The city's 4 water systems serve approximately 4,986 residents using groundwater (wells).

The concern

Copper is over its legal limit

Measured at 2.44 mg/L against the EPA Action Level of 1.3 mg/L. The ledger below shows how far over — and which filter removes it.

The good news

Lead is well under the limit

90th-percentile lead is 0.0 ppb — beneath the 15 ppb federal action level and under the 5 ppb watch threshold.

Washington Twp.-1438's drinking water received a grade of F (38 out of 100), indicating failing water quality. The city's 4 water systems serve approximately 4,986 residents using groundwater.

Lead levels were measured at 0.0 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 6 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply. The system has 313 violations on record, including 22 health-based violations. 29 remain unresolved.

Washington Twp.-1438 ranks #417 out of 426 cities in New Jersey for water quality, placing it among the lowest-rated in the state. Washington Twp.-1438 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. Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon. Hexavalent chromium (chromium-6) was detected at 0.37 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. The system has seen 16 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

04Where Washington Twp.-1438's water comes from

Washington Twp.-1438's drinking water is drawn from underground aquifers through wells.

Source

Groundwater

Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.

Treatment

Local treatment

Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.

Distribution

4 systems

4 water systems, operated under local government ownership.

Delivery

4,986 people

Residents served across Washington Twp.-1438'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 4,986 people through 4 water systems.
