Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 60 Nevada systems (9.3%) list purchased surface water as their primary source.

Does Boulder City have drinking water violations?
EPA's records list 5 violations for this system; none is health-based, and the most recent began in April 2003. The violations listed here began between June 1991 and April 2003. By type: 5 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 4 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.
