How does Chinese Camp School compare with other water systems in Tuolumne County?
By EPA's size categories, Chinese Camp School is a very small system (500 people or fewer). Tuolumne County has 117 active public water systems. Its population served is well below the county average of 706 people per system, and accounts for less than 0.1% of the 82,611 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 Chinese Camp School 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 Chinese Camp School?
EPA lists Chinese Camp School as owned by a local government. 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. 17 of the 117 active systems in Tuolumne County (15%) are also owned by a local government.
Does Chinese Camp School have drinking water violations?
EPA's records list 7 violations for this system; 4 are health-based, and the most recent began in April 2025. The violations listed here began between December 1982 and April 2025. By type: 4 contaminant level above the legal limit, 2 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 5 as resolved and 2 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.
