How does Cave Lake State Park compare with other water systems in White Pine County?
By EPA's size categories, Cave Lake State Park is a small system (501 to 3,300 people). White Pine County has 26 active public water systems, and Cave Lake State Park is the 2nd-largest of them by population served. Its population served is about 4 times the county average of 498 people per system, and accounts for 15% of the 12,946 people reported by systems filed under the county.

Nationally, the average active transient non-community water system reports serving 144 people, so Cave Lake State Park is about 14 times that figure.
What does “transient non-community water system” mean?
A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Nevada has 258 active transient non-community water systems, 40% of the state's 643 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 557 Nevada systems (87%) list groundwater as their primary source.
Who owns and regulates Cave Lake State Park?

The NV state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 3 of the 26 active systems in White Pine County (12%) are also owned by a state government.
Does Cave Lake State Park have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in March 2023. The violations listed here began between November 2002 and March 2023. By type: 7 monitoring and reporting, 3 contaminant level above the legal limit, 1 reporting and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 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.
