Relating to the adoption of a healthy and safe school water plan by public schools.

SB 191 requires all Texas public school districts and open-enrollment charter schools to adopt a "healthy and safe school water plan" by September 1, 2026. The plan must include regular lead testing at all water sources used for drinking or food preparation, with immediate access restrictions if lead levels exceed 15 parts per billion (within 48 hours), followed by contamination mitigation and retesting before normal access resumes. The Texas Education Agency must develop a model plan by December 2025 and may reimburse districts for testing costs if funds are available. This law directly affects every public school in Texas, mandating proactive lead testing and remediation to protect student and staff health.
