Are wells in Ector County getting deeper?
Home well depth in Ector County has not changed meaningfully: the median was 130 feet in 2003 to 2007 and 140 feet in 2021 to 2025 (a difference under 10% or within the margin of error). The water level measured when each well was finished is also lower: 80 feet then, 100 feet now. Read the 20-year study.
Aquifers under the county
The Texas Water Development Board maps the Edwards-Trinity (Plateau), a major aquifer, at the surface (outcrop) across 56% of the county and below other rock (subsurface) across 23% of the county; the Ogallala, a major aquifer, at the surface (outcrop) across 23% of the county; the Pecos Valley, a major aquifer, at the surface (outcrop) across 21% of the county; the Dockum, a minor aquifer, under 100% of the county.
