Midland's Water Quality Report, Explained
The city's annual report runs about twenty pages, most of it a source table. Here's what the numbers say and what they mean for treatment at home.
Midland's 2025 Consumer Confidence Report shows no violations. Water comes from Colorado River Municipal Water District reservoirs and city well fields, disinfected with chloramines averaging 2.44 ppm. Hardness isn't in the report; the city's FAQ puts it at 400–600 ppm, about 23 to 35 grains per gallon.
Where the water comes from
The City of Midland Water Purification Plant (public water system TX1650001) uses surface water owned and bought through the Colorado River Municipal Water District, from O.H. Ivie Reservoir, E.V. Spence Reservoir, Lake J.B. Thomas and other district sources. Groundwater comes from the city-owned T-Bar Wellfield in the Pecos Aquifer in Loving and Winkler Counties. The report's source table also lists the Paul Davis well field, a group of Clearwater wells in Winkler County, and a supply interconnect with Midland County Fresh Water Supply District 1.
Hardness lives in the FAQ
You won't find hardness in the 2025 report's tables, because it isn't a regulated contaminant. The city answers it separately: 400 to 600 parts per million, divided by 17.12 for grains per gallon. That's about 23.4 to 35 grains, very hard by any common scale. The city doesn't split it by source, so treat the whole range as possible at your tap.
What was detected, and the limits
- Chloramines: 2.44 ppm average, range 0.05 to 5.5 ppm; the limit is 4 ppm as an annual average.
- Arsenic: highest 9.19 ppb, range 1.5 to 9.19; limit 10 ppb.
- Fluoride: highest 1.52 ppm; limit 4 ppm.
- Nitrate: highest 1.21 ppm; limit 10 ppm.
- Lead: 90th percentile 1.5 ppb in 2021 to 2023 sampling, no sites over the 15 ppb action level, and no known lead service lines on record.
All figures are from the City of Midland 2025 CCR.
PFAS sampling
Under the EPA's fifth unregulated contaminant rule, Midland sampled in 2024. The report lists PFHxS at an average of 9.1 parts per trillion, PFBA at 15 ppt and PFBS at 4.2 ppt, and states these detections do not indicate a violation. PFOA and PFOS are not among the detections listed. In May 2026 the EPA proposed rescinding its PFHxS limit while keeping the 4 ppt limits for PFOA and PFOS (EPA).
Turning it into a plan
Hardness is the number that drives most decisions here, which is why sizing gets its own attention on the softener installation page. Chloramine taste points to carbon, and drinking water preferences point to reverse osmosis. You can also check the system's data on TCEQ's Drinking Water Watch by searching for system 1650001.
