What Makes New River's Water Unique?
Local geology and source profile
New River, Arizona, in Maricopa County — an unincorporated Maricopa County community adjacent to Anthem and Desert Hills in the north Phoenix Valley — receives its water from local wells drawing from the New River alluvial basin groundwater (Maricopa County) through the north Phoenix distribution or private wells.
The extremely hard 393.5 mg/L hardness and very high TDS of 1161.7 mg/L reflect the extreme north Phoenix Valley alluvial basin evaporitic groundwater character — among the hardest in the entire USA dataset. The New River alluvial basin at Maricopa County is developed in Quaternary New River alluvium (calcareous, derived from Precambrian crystalline and calcareous Paleozoic terranes — primary hardness contributor), highly concentrated by Arizona Basin-and-Range closed-basin evaporitic enrichment (halite and gypsum — dominant TDS contributor from Cenozoic evaporitic lacustrine sediments), and Precambrian crystalline hard-rock leaching. The closed-basin concentration and evaporitic enrichment produce the extreme north Phoenix supply.
At 393.5 mg/L with TDS 1162, New River's water is extremely hard. A water softener is essential, and a reverse osmosis system is strongly recommended for drinking water. Scale accumulates very rapidly on all surfaces and appliance lifespans are extremely shortened. The PFAS level of 5.3 ppt warrants a certified drinking water filter — the Luke Air Force Base (Maricopa County — AFFF) and the north Phoenix metro PFAS background contribute.
