How does Buffalo Water Supply compare with other water systems in Scott County?
By EPA's size categories, Buffalo Water Supply is a small system (501 to 3,300 people). Scott County has 78 active public water systems. Its population served is about half of the county average of 2,285 people per system, and accounts for 0.7% of the 178,240 people reported by systems filed under the county.

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. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,502 Iowa systems (82%) list groundwater as their primary source.
Who owns and regulates Buffalo Water Supply?
EPA lists Buffalo Water Supply as owned by a local government. 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. 20 of the 78 active systems in Scott County (26%) are also owned by a local government.
Does Buffalo Water Supply have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in October 2007. The violations listed here began between April 1988 and October 2007. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Fluoride (2 of them). EPA lists 11 as resolved and 1 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.
