How does Virginia Dare Winery compare with other water systems in Sonoma County?

By EPA's size categories, Virginia Dare Winery is a very small system (500 people or fewer). Sonoma County has 441 active public water systems.

Across California, the 7,479 active systems average 5,706 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Virginia Dare Winery 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. California has 1,466 active non-transient non-community water systems, 20% of the state's 7,479 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,179 California systems (83%) list groundwater as their primary source.

Who owns and regulates Virginia Dare Winery?

EPA lists Virginia Dare Winery as privately owned. The CA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 371 of the 441 active systems in Sonoma County (84%) are also privately owned.

Does Virginia Dare Winery have drinking water violations?

EPA's records list 4 violations for this system; 1 is health-based, and the most recent began in October 2024. The violations listed here began between August 1984 and October 2024. By type: 1 required treatment not met, 1 reporting, 1 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Lead and Copper Rule Revisions (2 of them). EPA lists 2 as unaddressed, 1 as resolved and 1 as archived. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
