How does Pinecrest compare with other water systems in San Diego County?
By EPA's size categories, Pinecrest is a very small system (500 people or fewer). San Diego County has 191 active public water systems. Its population served is well below the county average of 19,427 people per system, and accounts for less than 0.1% of the 3,710,459 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 Pinecrest is about half of that figure.

California has 3,016 active transient non-community water systems, 40% 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 Pinecrest?

Does Pinecrest have drinking water violations?
EPA's records list 7 violations for this system; none is health-based, and the most recent began in January 2005. The violations listed here began between December 1982 and January 2005. By type: 5 public notice, recordkeeping or other and 2 monitoring and reporting. The contaminants or rules involved are Nitrate-Nitrite and Total coliform bacteria (TCR). EPA lists 5 as archived and 2 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.
