Groundwater means the system draws its water from wells or springs fed by underground aquifers. 966 Louisiana systems (86%) list groundwater as their primary source.
Who owns and regulates La Casa LLC?

Does La Casa LLC have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in July 2025. The violations listed here began between January 1994 and July 2025. By type: 6 public notice, recordkeeping or other, 3 contaminant level above the legal limit, 2 required treatment not met and 1 monitoring and reporting. The contaminant or rule involved most often is Consumer Confidence Rule (4 of them). EPA lists 7 as resolved, 3 as archived and 2 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
