FAQs

What does PWSID TX1560002 mean?

A Public Water System Identification number uniquely identifies a system in EPA’s Safe Drinking Water Information System (SDWIS). Texas IDs start with TX.

How current is this page?

Systems and geography reflect the EPA SDWA quarterly snapshot used for this build. Violation rows are a filtered recent subset (generally 2021+) and capped for readability—always confirm on ECHO and your CCR.

What should I do if I see a health-based violation?

Read the dates and status. Contact the utility for context, check for public notices, and review the newest Consumer Confidence Report. For medical concerns, talk with a clinician—this site is educational only.

Do lead/copper samples mean my home is safe?

LCR samples are utility monitoring results (often 90th percentile summary codes like PB90/CU90), not a test of every tap. Home plumbing can differ. Consider a certified lab test if you have reason for concern.
