How does Mountain Loop View Tracts compare with other water systems in Snohomish County?
By EPA's size categories, Mountain Loop View Tracts is a very small system (500 people or fewer). Snohomish County has 167 active public water systems. Its population served is well below the county average of 6,200 people per system, and accounts for less than 0.1% of the 1,035,433 people reported by systems filed under the county. Across Washington, the 4,705 active systems average 2,172 people each. Nationally, the average active community water system reports serving 6,703 people, so Mountain Loop View Tracts is well below that figure.
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. Washington has 2,392 active community water systems, 51% of the state's 4,705 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 4,370 Washington systems (93%) list groundwater as their primary source.
Who owns and regulates Mountain Loop View Tracts?

The WA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 126 of the 167 active systems in Snohomish County (75%) are also privately owned.
Does Mountain Loop View Tracts have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in March 2025. The violations listed here began between August 1996 and March 2025. By type: 8 monitoring and reporting, 3 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Nitrate (4 of them). EPA lists 8 as resolved and 4 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.
