Analysis

What to know about Berkeley Twp.-1505's water

Berkeley Twp.-1505 ranks #305 out of 435 cities in New Jersey for water quality, placing it below average in the state.

Berkeley Twp.-1505 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.

PFAS compounds were detected in testing, though levels remain within current EPA limits. Residents seeking extra precaution may consider an activated carbon or reverse osmosis filter.

Hexavalent chromium (chromium-6) was detected at 0.28 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 19 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Where Berkeley Twp.-1505's water comes from

Groundwater

Berkeley Twp.-1505's drinking water is drawn from underground aquifers through wells.

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 private ownership and serves approximately 30,392 people through 3 water systems.
