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.

Does Wilderness Estates have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in April 2013. The violations listed here began between January 2011 and April 2013. By type: 11 monitoring and reporting and 1 required treatment not met. The contaminants or rules involved are Groundwater Rule, Thallium, Beryllium and Cyanide. 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.
