What Makes Avenel's Water Unique?
Local geology and source profile
Avenel, New Jersey, in Middlesex County — an unincorporated Middlesex County community adjacent to Woodbridge and Rahway in the northeast New Jersey industrial corridor — receives its municipal water from New Jersey American Water, drawing from the Raritan River (Round Valley Reservoir, Somerset County) through the NJ American Water treatment system.
The very hard 176.5 mg/L hardness and elevated TDS of 464.5 mg/L reflect the Middlesex County Raritan River supply's Triassic-Precambrian mixed character. The Raritan River at this watershed draws from the New Jersey Highlands Precambrian Reading Prong (insoluble — softness source) and the Triassic Newark Basin Brunswick Formation (calcareous redbeds — the dominant Middlesex County hardness contributor). The Triassic calcareous loading produces the elevated hardness.
At 176.5 mg/L, Avenel's water is very hard — scale builds rapidly in kettles and appliances, a water softener is strongly recommended, and water heaters require annual maintenance. The PFAS level of 12.8 ppt warrants a certified reverse osmosis drinking water filter — the Middlesex County petrochemical and chemical manufacturing corridor (one of the most industrialized counties in the US), Avenel and the adjacent Woodbridge industrial zone (a historic New Jersey PFAS manufacturing and disposal complex), and the north New Jersey PFAS complex produce Avenel's very elevated readings.
Geology & Source: Avenel in Middlesex County draws from NJ American Water on Round Valley Reservoir or the Raritan River (Middlesex County, New Jersey) — the Raritan-Round Valley system drains the New Jersey Highlands (Precambrian Reading Prong gneiss) and Triassic Newark Basin (calcareous redbeds) — New Jersey Middlesex County Raritan River Triassic-Precambrian watershed produces very hard water at 176.5 mg/L with TDS 464.5 mg/L in this Middlesex County New Jersey community.
