Groundwater means the system draws its water from wells or springs fed by underground aquifers. 5,215 Texas systems (74%) list groundwater as their primary source.

Who owns and regulates Grey Forest Water System?

Does Grey Forest Water System have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in May 2025. The violations listed here began between October 2008 and May 2025. By type: 7 monitoring and reporting, 3 public notice, recordkeeping or other, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Chlorine (6 of them). EPA lists 11 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
