Well & Groundwater Services in Phoenix, AZ

Well & Groundwater Services in Phoenix, Arizona

Phoenix is one of the world’s great water management stories — a city of 1.6 million people built in the Sonoran Desert, sustained by a carefully engineered combination of Colorado River water, Salt River water stored in a network of Roosevelt-era reservoirs, and increasingly, reclaimed and recharged groundwater. But beneath the sprawling metro, hundreds of older properties, ranchettes on the urban fringe, and agricultural holdouts still rely on private wells reaching deep into the alluvial aquifer that underlies the Salt River Valley.

Ten licensed groundwater contractors operate in Phoenix proper, offering the full range of drilling, pump service, and water treatment.

Phoenix’s Groundwater Context

Phoenix sits within the Phoenix Active Management Area, where the Arizona Department of Water Resources tightly regulates groundwater withdrawals. The city’s water utility (Phoenix Water Services) delivers treated water to most Phoenix addresses, but areas in the northwestern, southern, and eastern portions of the city — as well as many properties on large lots — remain on private wells.

The Phoenix basin aquifer is a multilayered system of alluvial sediments. Productive residential wells typically reach 400–900 feet to tap the middle aquifer zones. The city has experienced land subsidence in the past from over-pumping; ongoing management has stabilized subsidence in most areas.

Water Quality in Phoenix Wells

Hardness: Very hard, typically 350–500+ mg/L. Nearly all Phoenix well homes run water softeners.
Arsenic: PFAS contamination from Luke Air Force Base affects parts of the northwest Phoenix / Goodyear / Litchfield Park area. If your well is in this zone, PFAS testing is essential.
TDS: 700–1,500 mg/L is common; reverse osmosis for drinking water is widespread.
Nitrates: Some areas in south Phoenix with legacy agricultural use show elevated nitrates in shallow wells.
