Randolph Twp.-1432 ranks #59 out of 426 cities in New Jersey for water quality, placing it above average in the state. Randolph Twp.-1432 purchases its water from a regional wholesaler, meaning quality depends on both the supplier's treatment and the local distribution system's condition. Hexavalent chromium (chromium-6) was detected at 0.69 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.
02What's in Randolph Twp.-1432's water
Every contaminant flagged in Randolph Twp.-1432, 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.
