waterverge.com Hillside Twp.-2007, NJ — Water Quality Report
Hillside Twp.-2007's drinking water received a grade of F (42 out of 100), indicating failing water quality. The city's 2 water systems serve approximately 329,403 residents using surface water.
Lead levels were measured at 1.1 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 1 PFAS compound, with levels exceeding EPA maximum contaminant levels in the water supply.
The system has 280 violations on record, including 67 health-based violations. 50 remain unresolved.
What to know about Hillside Twp.-2007's water
Hillside Twp.-2007 ranks #407 out of 435 cities in New Jersey for water quality, placing it among the lowest-rated in the state.
The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection.
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.
Disinfection byproduct (HAA5) levels exceeded the EPA's 60 µg/L maximum contaminant level in UCMR 4 testing (2018–2020). These compounds form when chlorine reacts with natural organic matter and have been linked to increased cancer risk with long-term exposure.
Hexavalent chromium (chromium-6) was detected at 0.08 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 28 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
