Well Water Treatment
Eliminate the rust staining and rotten egg smell from your well’s water
Explore serviceCooke County splits between treated municipal water in Gainesville, Muenster, and Lindsay and private wells across the rural parts of the county. The two call for different equipment, and the dividing line is closer to a property line than to a county line.
Local Water
Gainesville and the smaller incorporated towns run on treated surface water. Municipal treatment targets pathogens and regulated contaminants, so what reaches the tap is safe — but hardness is not a health-based standard and largely passes through treatment, which is why scale on fixtures and inside water heaters is the common complaint in town, alongside the taste of the disinfectant residual.
Outside those systems, households are on wells drawing from the Trinity group. Well water in this area tends to be hard, and iron and sulfur turn up often enough to be worth testing for specifically. Because nobody is monitoring a private well on a schedule, the owner’s own test result is the only record of what is actually in it.

Local Water Data
19 community water systems serve Cooke County, between them supplying about 42,460 people. 1 draw from surface water and 18 from groundwater — a distinction that changes what the water carries and what treating it takes.
If your address is on one of these systems, its water quality is already a matter of public record, and that is where we start. If you are on a private well, none of this describes your water — no utility tests it, and what is in it comes down to your well and your formation.
Where this comes from. System names, populations and water sources are from the EPA's Safe Drinking Water Information System, a public record. The linked reports are published by the Environmental Working Group, an independent non-profit; EWG's health guidelines are its own and are stricter than federal legal limits, so a system can exceed them while fully complying with the law. Your utility also publishes an annual Consumer Confidence Report covering the same system from its own testing — ask them for it, or look for it on their website.
Well Water
The state has sampled 211 wells in Cooke County, most of them drawing from the Trinity aquifer. Those results describe the formation, not your well — but they set the baseline we start from when you are not on a city system.
0.5 gpg
already soft
Half of sampled wells fall between 0.3 and 0.9 gpg.
76%
Under 1 gpg untreated
Most wells here need no softening at all — worth knowing before anyone sells you one.
11%
Above 0.3 mg/L
0.3 mg/L is where iron starts leaving orange marks in fixtures and laundry.
8.7
Alkaline
Within the range where plumbing is not usually at risk.
These are formation averages. Individual wells in Cooke County vary widely with depth and formation: 19 in 20 sampled wells come in under 20 gpg, and the rest run higher still. A full water panel is the only way to know what a specific well holds, and we recommend one, though you do not need a panel to get better water. Figures are from the Texas Water Development Board Groundwater Database, a public record.
