Greentree Water Hardness & Quality Report (2026)

Greentree, an unincorporated community within Voorhees Township, Camden County, New Jersey, gets its water from New Jersey American Water Company's Western System. This utility draws from a variety of sources, including surface water from the Delaware River, treated at the Delaware River Water Treatment Plant in Carneys Point. Groundwater from Coastal Plain aquifers, specifically the Cohansey and Wenonah-Mount Laurel formations, also contributes to the supply. The water serves over 300,000 customers across 68 municipalities, including Voorhees, with distribution reaching Camden, Gloucester, and Burlington counties. The Delaware River Basin is the primary watershed, though local recharge can be influenced by tributaries like the Cooper River.

Geologically, Greentree's water originates from the New Jersey Coastal Plain. The primary aquifers here are the Cohansey-Kirkwood system and the Wenonah-Mount Laurel aquifer, composed of sands, gravels, silts, and clays dating back to the late Cretaceous to Miocene periods. These formations contain significant amounts of calcium carbonate, derived from shell fragments and limestone pebbles eroded from further inland. The presence of limestone within the Mount Laurel Formation further contributes to the water's hardness as groundwater passes through. This geological makeup naturally imparts a hard water profile due to the dissolution of minerals like calcium and magnesium.

Homeowners in Greentree may notice scale buildup on fixtures, in appliances like dishwashers and water heaters, and potentially duller-looking laundry. Kettles can develop a chalky residue, and the efficiency of appliances might decrease over time due to mineral deposits. To combat this, regular descaling of coffee makers and humidifiers with vinegar is recommended. Installing scale-inhibiting filters can also help manage the mineral content. For a more comprehensive solution, a water softener is often advised to improve soap lathering, prevent spotting on glassware, and extend the lifespan of household equipment.
