What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Iowa has 1,084 active community water systems, 59% of the state's 1,828 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 156 Iowa systems (8.5%) list purchased groundwater as their primary source.
Who owns and regulates Westwood Water Supply?

The IA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 10 of the 11 active systems in Henry County (91%) are also owned by a local government.
Does Westwood Water Supply have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in February 2018. The violations listed here began between September 1980 and February 2018. By type: 12 monitoring and reporting. The contaminants or rules involved are Lead and Copper Rule, Total coliform bacteria (TCR), Barium and Nitrate. EPA lists 10 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.
