How does Langlois Water District compare with other water systems in Curry County?

By EPA's size categories, Langlois Water District is a very small system (500 people or fewer). Curry County has 36 active public water systems. Its population served is about 58% below the county average of 525 people per system, and accounts for 1.2% of the 18,894 people reported by systems filed under the county. Across Oregon, the 2,536 active systems average 1,587 people each. Nationally, the average active community water system reports serving 6,703 people, so Langlois Water District is well below that figure.

What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. Oregon has 940 active community water systems, 37% of the state's 2,536 active systems. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 211 Oregon systems (8.3%) list surface water as their primary source.

Who owns and regulates Langlois Water District?

The OR state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 10 of the 36 active systems in Curry County (28%) are also owned by a local government.

Does Langlois Water District have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2025. The violations listed here began between January 2025 and July 2025. By type: 11 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminants or rules involved are Consumer Confidence Rule, Ethylbenzene, 1,2-Dichloropropane and 1,1-Dichloroethylene. EPA lists 11 as archived and 1 as resolved. 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. 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.
