How does Northern Lights Terrace compare with other water systems in Matanuska-Susitna Borough County?

By EPA's size categories, Northern Lights Terrace is a very small system (500 people or fewer). Matanuska-Susitna Borough County has 342 active public water systems.

Across Alaska, the 1,322 active systems average 653 people each.

What does “community water system” mean?

A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Alaska has 406 active community water systems, 31% of the state's 1,322 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,054 Alaska systems (80%) list groundwater as their primary source.

Who owns and regulates Northern Lights Terrace?

EPA lists Northern Lights Terrace as privately owned. The AK state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 282 of the 342 active systems in Matanuska-Susitna Borough County (82%) are also privately owned.

Does Northern Lights Terrace have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2026. The violations listed here began between October 1991 and January 2026. By type: 6 monitoring and reporting, 5 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Consumer Confidence Rule (3 of them). EPA lists 7 as resolved, 4 as unaddressed and 1 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
