What does “non-transient non-community water system” mean?

Louisiana has 125 active non-transient non-community water systems, 11% of the state's 1,121 active systems. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 53 Louisiana systems (4.7%) list surface water as their primary source.
Who owns and regulates Shell Chemical Company?

The LA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 23 of the 27 active systems in Ascension Parish County (85%) are also privately owned.
Does Shell Chemical Company have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in January 2022. The violations listed here began between January 2005 and January 2022. By type: 10 monitoring and reporting and 2 required treatment not met. The contaminant or rule involved most often is Carbon, total (9 of them). EPA lists 7 as resolved and 5 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.
