How does D Stake Mill compare with other water systems in Yamhill County?

By EPA's size categories, D Stake Mill is a very small system (500 people or fewer). Yamhill County has 91 active public water systems.

Nationally, the average active non-transient non-community water system reports serving 430 people, so D Stake Mill is well below that figure.

What does “non-transient non-community water system” mean?

A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Oregon has 346 active non-transient non-community water systems, 14% of the state's 2,536 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,175 Oregon systems (86%) list groundwater as their primary source.

Who owns and regulates D Stake Mill?

EPA lists D Stake Mill as privately owned. The OR state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 71 of the 91 active systems in Yamhill County (78%) are also privately owned.

Does D Stake Mill have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in November 2024. The violations listed here began between January 2023 and November 2024. By type: 11 monitoring and reporting and 1 monitoring. The contaminants or rules involved are Revised Total Coliform Rule, Dalapon, Toxaphene and Trichloroethylene. 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.
