Good Water on Paper Doesn't Mean Good Water in the Glass
Polk County groundwater draws mostly from the Carrizo-Wilcox and Queen City aquifer systems, the same formations the Lower Trinity Groundwater Conservation District permits and tracks for wells across the county. That's a reasonable baseline for water quality, but it doesn't tell you what's happening in your specific casing, your specific pipe, or your specific pressure tank.
Bacteria contamination is the most common surprise we find, usually tied to a wellhead seal that's degraded or a casing that sits below grade and lets surface water seep in during heavy rain. Older properties near the shoreline see this more than newer builds because a lot of the original well caps predate current sealing standards. Iron and manganese staining is the second most common complaint, showing up as rust-colored rings in sinks and tubs, which is a mineral issue rather than a health issue but wears out fixtures and water heaters faster.
If you're on a private well, nobody tests your water for you the way a municipal supplier would. Testing is on you, and we make it a same-visit, no-guesswork process.
