Frequently Asked Questions
What should I test my well water for in Texas?
TCEQ recommends testing private wells at least annually for total coliform bacteria and nitrates. Given Texas's mix of agriculture, industry, oil and gas production, and coastal salinity, also consider nitrates in farm-heavy areas, chlorides where saltwater intrusion is a concern, sulfate and trace metals in some aquifers, and VOCs near industrial or petroleum activity—plus lead, arsenic, iron, manganese, and pH. Texas A&M AgriLife Extension and TCEQ publish guidance on regional contaminants of concern.
How often should well water be tested in Texas?
Test annually for bacteria and nitrates. Comprehensive testing every 2-3 years is recommended. Test immediately after any flooding event, if you notice changes in taste, odor, or color, or if you receive a notice about contamination in your area from local authorities.
Where can I get my well water tested in Texas?
Use a state-certified laboratory. Your local board of health, state university cooperative extension office, or environmental watch program can provide sampling kits and recommend certified labs. Some well service companies also partner with certified labs.
How much does well water testing cost in Texas?
Basic bacterial and nitrate testing costs $75-$150. A standard potable water panel (bacteria, nitrates, pH, iron, manganese, hardness) costs $150-$300. Extended testing for specific contaminants adds $150-$300 per sample. A comprehensive panel including multiple contaminant types costs $400-$700.
