Power comes from JCP&L
JCP&L (Jersey Central Power & Light Co.), an investor-owned utility, serves all of Columbia. Its homes paid an average of 18.4¢ per kWh in 2025, about $145 a month (its average across New Jersey, for customers on its standard service). New Jersey lets you buy power from another supplier; 9% of JCP&L’s home customers do, and JCP&L still delivers it.
Service territory: HIFLD Electric Retail Service Territories (map dated Aug 2023). Prices and customers: EIA-861, 2025.
Water comes from Clover Rest Home water system
The Clover Rest Home water system supplies Columbia: about 23% of residents live in its service area. About 77% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It draws ground water and serves 64 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 78% of the 11,392 systems serving <=100 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2023–Dec 2025, was 0.0 ppb, below the 15 ppb action level that applied. The highest in five years was 8.8 ppb. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
