Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 9 Hawaii systems (6.6%) list surface water as their primary source.
Who owns and regulates Lower Kula?

The HI state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 12 of the 39 active systems in Maui County (31%) are also owned by a local government.
Does Lower Kula have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in January 2017. The violations listed here began between April 1995 and January 2017. By type: 8 monitoring and reporting, 3 contaminant level above the legal limit and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 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.
