Olympian Water Testing™

Montgomery Township New Jersey water supply history originates with its 1798 incorporation in Somerset County, where early rural residents relied exclusively on private wells tapping local aquifers amid farmland and the Sourland Mountains, as noted in Montgomery Township’s historical overview. This self-sufficient approach suited the sparse population until mid-20th-century suburban growth.

Well water systems in Montgomery Township faced challenges in the 1970s when groundwater contamination by trichloroethylene (TCE) was detected in private wells at the Montgomery Township Housing Development, a 72-acre Superfund site. Investigations from 1978 revealed TCE levels up to 200 μg/L, prompting federal intervention, as detailed by the U.S. Environmental Protection Agency. A 1987 Record of Decision mandated connecting affected homes to public water to mitigate health risks.

Municipal water development in Montgomery Township, NJ, expanded through New Jersey American Water, which now serves about two-thirds of the township’s 24,000 residents via its Raritan System. Sourced primarily from surface water at the Raritan-Millstone Plant and supplemented by groundwater, the system spans extensive mains under New Jersey Department of Environmental Protection oversight. The remaining third of homes use private wells, regulated by the Private Well Testing Act, with resources available on the township’s health page.

Quality monitoring, including for contaminants like arsenic and PFAS, is reported by the Environmental Working Group, reflecting ongoing upgrades amid population pressures and environmental protections since the shift from predominant well reliance.
