Parameters with reported violations
Most common violated parameter
All figures count EPA-reported records for the plants currently selected. Monitoring and reporting frequency varies by permit, so record counts are not performance scores. Infrastructure Intelligence methodology.
Select a bar to filter every view to that parameter.
Bars count violation records; the line counts distinct plants affected. More records does not by itself mean worse statewide performance, because monitoring frequency differs between permits.
EPA assigns major/minor status by permit. Neither group is better or worse; the groups simply have different monitoring obligations.
Counties hold very different numbers of plants, so the share column always carries its denominator.
| County | Public POTWs | With reported violations | Violation records | |

Ordered by number of reported records only. Monitoring requirements and reporting frequency vary among permits, so these counts are not performance scores or rankings.
Plants where EPA recorded three or more effluent violations for the same parameter in this period. This states what the records show; it does not identify a cause.
Compatible upper-bound series only: the reported value and the applicable limit share the same outfall, monitoring location, statistical basis and EPA standard unit. Minimum limits and incompatible series are excluded. A value near its limit is not a violation.
