How does Lockheed Martin Space Systems compare with other water systems in Santa Cruz County?
By EPA's size categories, Lockheed Martin Space Systems 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 non-transient non-community water system reports serving 430 people, so Lockheed Martin Space Systems 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. 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 Lockheed Martin Space Systems?
EPA lists Lockheed Martin Space Systems as privately owned. 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. 76 of the 96 active systems in Santa Cruz County (79%) are also privately owned.
Does Lockheed Martin Space Systems have drinking water violations?
EPA's records list 8 violations for this system; 5 are health-based, and the most recent began in December 2024. The violations listed here began between July 2017 and December 2024. By type: 5 required treatment not met, 2 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Surface Water Treatment Rule (4 of them). EPA lists 4 as resolved, 3 as archived and 1 as addressed. 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement.
