How does Pavestone compare with other water systems in Yolo County?

By EPA's size categories, Pavestone is a very small system (500 people or fewer). Yolo County has 88 active public water systems. Its population served is well below the county average of 2,951 people per system, and accounts for less than 0.1% of the 259,714 people reported by systems filed under the county. 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 Pavestone 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 Pavestone?

EPA lists Pavestone 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. 69 of the 88 active systems in Yolo County (78%) are also privately owned.

Does Pavestone have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2018. The violations listed here began between January 2017 and July 2018. By type: 11 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminants or rules involved are Consumer Confidence Rule, Antimony, Nickel and Beryllium. 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.
