How does Whitewood compare with other water systems in Lawrence County?
By EPA's size categories, Whitewood is a small system (501 to 3,300 people). Lawrence County has 73 active public water systems, and Whitewood is the 4th-largest of them by population served. Its population served is about 136% above the county average of 373 people per system, and accounts for 3.2% of the 27,194 people reported by systems filed under the county. Across South Dakota, the 699 active systems average 1,387 people each. Nationally, the average active community water system reports serving 6,703 people, so Whitewood is well below that figure.
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. South Dakota has 510 active community water systems, 73% of the state's 699 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 431 South Dakota systems (62%) list groundwater as their primary source.
Who owns and regulates Whitewood?
EPA lists Whitewood as owned by a local government. The SD 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 73 active systems in Lawrence County (14%) are also owned by a local government.
Does Whitewood 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 1997. The violations listed here began between January 1993 and February 1997. By type: 11 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Lead and Copper Rule (2 of them). 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.
