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. Nebraska has 138 active non-transient non-community water systems, 11% of the state's 1,226 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 88 Nebraska systems (7.2%) list purchased groundwater as their primary source.

Does Clay Co Sid #1 have drinking water violations?
EPA's records list 4 violations for this system; 2 are health-based, and the most recent began in August 2015. The violations listed here began between July 1993 and August 2015. By type: 2 contaminant level above the legal limit, 1 public notice, recordkeeping or other and 1 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 of them). EPA lists 2 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.
