Chatham Borough pumps from three wells in the Buried Valley Aquifer and treats with chlorination only; there is no softening at the plant, so the hardness that comes with groundwater arrives at your tap. The borough’s latest report shows PFOA at 2.53 ppt against a 14 ppt limit and lead at 1.4 ppb at the 90th percentile, both well within standards, and it can supplement from New Jersey American Water and Madison when needed.
Chatham Township homes are served by New Jersey American Water, a blended system of reservoirs, river intakes, wells and purchased water. Blended supply means chlorine level, taste and hardness can shift from week to week, which is the most common reason Township customers call us.
