• Well Maintenance & Records: Keep detailed records of the well’s depth, casing, and pump.
• Contamination Risks: Be aware of potential risks from nearby septic systems, livestock, or agricultural runoff.
• Resources: The Texas Well Owner Network (TWON) has fantastic education and resources.
• Contamination Notice: As of September 1, 2025, TCEQ is required to notify residents within one mile of a groundwater contamination site.
