How does Southgate S/D compare with other water systems in Johnston County?
By EPA's size categories, Southgate S/D is a very small system (500 people or fewer). Johnston County has 54 active public water systems. Its population served is well below the county average of 3,982 people per system, and accounts for less than 0.1% of the 214,999 people reported by systems filed under the county. Across North Carolina, the 5,087 active systems average 1,971 people each. Nationally, the average active community water system reports serving 6,703 people, so Southgate S/D 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. North Carolina has 2,031 active community water systems, 40% of the state's 5,087 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 331 North Carolina systems (6.5%) list purchased surface water as their primary source.
Who owns and regulates Southgate S/D?
EPA lists Southgate S/D as privately owned. The NC state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 37 of the 54 active systems in Johnston County (69%) are also privately owned.
Does Southgate S/D have drinking water violations?
Of the 12 most recent violations in EPA's records, 7 are health-based, and the most recent began in July 2023. The violations listed here began between July 2007 and July 2023. By type: 7 contaminant level above the legal limit, 4 public notice, recordkeeping or other and 1 reporting. The contaminant or rule involved most often is Combined Radium (-226 and -228) (7 of them). EPA lists 7 as archived and 5 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.
