What Makes Andrews's Water Unique?
Local geology and source profile
The City of Andrews utility provides water to roughly 14,109 residents in Andrews and surrounding areas of Andrews County, Texas. Their supply comes entirely from groundwater drawn from the Dockum Aquifer through a network of wells. While specific treatment plant names aren't publicly disclosed in available reports, the system has experienced several Maximum Contaminant Level (MCL) violations. Recent monitoring has identified 13 to 18 contaminants exceeding the EPA's health-based guidelines. Residents can reach the utility for service details at 432-523-4820 or the emergency line at 432-266-1550. The utility's mailing address is 111 Logsdon St, Andrews, TX 79714.
Andrews is situated within the Permian Basin watershed, where surface drainage helps recharge the Dockum Aquifer through permeable sands. The local geology is characterized by Triassic Dockum sandstones interbedded with Permian Whitehorse evaporites. These layers include dolomite, limestone, and gypsum, remnants of arid depositional environments. These soluble carbonate and sulfate-rich formations readily dissolve minerals, contributing significantly to the groundwater's hardness and its elevated calcium and magnesium content, which impacts its usability without treatment.
Significant scale buildup is a common consequence of the very hard water in Andrews, affecting pipes, water heaters, dishwashers, and washing machines. This buildup reduces efficiency and lifespan, often necessitating descaling every one to two years. You'll likely notice poor soap lathering, leaving films on fixtures and skin, and laundry may appear grayed over time. Regular maintenance, such as vinegar flushes for appliances, is advised, and installing water softeners is strongly recommended. Aiming for an effective hardness below 7 gpg can prevent costly repairs and extend the life of your equipment. The utility has documented 18 MCL violations, with multiple contaminants exceeding EPA guidelines, possibly including disinfection byproducts or inorganics typical of groundwater sources.
Geology & Source: Dockum Aquifer; Triassic sandstones and Permian evaporites including gypsum and limestone dissolve minerals, causing hardness

Data Sources & Methodology
Water quality data for Andrews is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.
Water Hardness
Modelled estimate based on state-level USGS geological survey data for this region. No direct USGS Water Quality Portal measurement was matched to this city — the value reflects a statistical range calibrated to the state's dominant rock types and typical source water characteristics.
pH
Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock — values may differ from utility-reported figures.
TDS — Total Dissolved Solids
Estimated using a derived ratio from water hardness and regional conductance profiles. TDS in natural water correlates strongly with total mineral content including hardness ions.
PFAS — Perfluoroalkyl and Polyfluoroalkyl Substances
EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023–2025) — sum of PFAS compounds detected at the public water system serving this city. A value of 0 indicates the system was sampled with no detection above reporting limits.
Lead
Modelled estimate based on the EPA Lead and Copper Rule 90th-percentile tap-sample methodology. No publicly available per-city lead dataset with sufficient national coverage exists. Values are a conservative baseline derived from city population tier and infrastructure age — all estimates are maintained below the EPA action level of 0.015 mg/L.
Appliance Lifespan
Calculated from water hardness using a linear degradation model. Baseline lifespans represent soft-water performance (kettle: 8.5 yrs, washing machine: 12.0 yrs, water heater: 15.0 yrs). Hard water mineral scale progressively reduces operational life in direct proportion to hardness concentration.
