From TCEQ notice of violation data. A notice of violation is an investigator's finding that the site must correct; it is not a final enforcement order or penalty, and many are resolved quickly. Septic (OSSF) cases at homes, residences and sites named after a person are excluded. Verify with TCEQ (Central Registry and compliance history).
