How does Quaker Center compare with other water systems in Santa Cruz County?
By EPA's size categories, Quaker Center is a very small system (500 people or fewer). Santa Cruz County has 96 active public water systems. Its population served is well below the county average of 2,856 people per system, and accounts for less than 0.1% of the 274,204 people reported by systems filed under the county. Across California, the 7,479 active systems average 5,706 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Quaker Center is well below that figure.
What does “transient non-community water system” mean?

California has 3,016 active transient non-community water systems, 40% of the state's 7,479 active systems. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 609 California systems (8.1%) list surface water as their primary source.
Who owns and regulates Quaker Center?

Does Quaker Center have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in September 2022. The violations listed here began between June 1984 and September 2022. By type: 7 monitoring and reporting, 4 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 8 as resolved and 4 as archived. 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.
