How does Oakdale S/D compare with other water systems in Mecklenburg County?

By EPA's size categories, Oakdale S/D is a very small system (500 people or fewer). Mecklenburg County has 62 active public water systems.

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 Oakdale S/D is well below that figure.

Does Oakdale S/D have drinking water violations?

By type: 10 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Nitrate (2 of them). EPA lists 10 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.
