By EPA's size categories, Crystal Lake Inc. is a very small system (500 people or fewer). Snohomish County has 167 active public water systems.

Nationally, the average active community water system reports serving 6,703 people, so Crystal Lake Inc. is well below that figure.

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.

Does Crystal Lake Inc. have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 1999. The violations listed here began between October 1979 and January 1999. By type: 12 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 11 as archived and 1 as resolved. 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. 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.
