What Makes Tinton Falls's Water Unique?
Local geology and source profile
Tinton Falls, New Jersey, in Monmouth County — a Monmouth County borough adjacent to Eatontown and Red Bank in the northern Monmouth County corridor — receives its municipal water from New Jersey American Water (NJAW), drawing from the Navesink River watershed (Monmouth County) and local wells accessing the Coastal Plain aquifer.
The hard 164 mg/L hardness and elevated TDS of 415.4 mg/L reflect the Monmouth County coastal plain calcareous aquifer. The Navesink watershed and Monmouth County Coastal Plain aquifer contact the Cretaceous Navesink Formation (calcareous glauconitic marl — high calcium-magnesium dissolution), the Cretaceous Wenonah Formation, and the Eocene Vincentown Formation (limestone fragments — additional carbonate contribution), producing the hard water characteristic of the Monmouth County coastal plain supply.
At 164 mg/L, Tinton Falls' water is hard — scale builds steadily in kettles and appliances, dishwashers benefit from rinse aid, and water heaters should be descaled annually. Monthly descaling is recommended. The PFAS level of 12.1 ppt is very elevated and warrants a certified reverse osmosis drinking water filter — Fort Monmouth (Monmouth County — historic US Army AFFF contamination site, one of the highest PFAS readings in New Jersey, directly adjacent to Tinton Falls), the Navesink River military-industrial corridor, and the Monmouth County PFAS complex produce Tinton Falls' very elevated PFAS readings.
Geology & Source: Tinton Falls in Monmouth County draws from New Jersey American Water on the Navesink River watershed (Monmouth County) and local aquifer wells — the Navesink drains the New Jersey Coastal Plain (Cretaceous Navesink Formation calcareous, Eocene Vincentown limestone) — New Jersey Monmouth County Cretaceous-Eocene coastal carbonate watershed produces hard water at 164 mg/L with TDS 415.4 mg/L in this Monmouth County New Jersey borough.
