By EPA's size categories, City of Sudan is a small system (501 to 3,300 people). Lamb County has 12 active public water systems, and City of Sudan is the 3rd-largest of them by population served.

What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. Texas has 4,594 active community water systems, 65% of the state's 7,078 active systems. 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 City of Sudan?

The TX state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 9 of the 12 active systems in Lamb County (75%) are also owned by a local government.
Does City of Sudan have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in April 2025. The violations listed here began between September 1993 and April 2025. By type: 6 monitoring and reporting, 4 contaminant level above the legal limit and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 9 as resolved and 3 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.
