What the violations mean
Nitrate-Nitrite
36 incidentsTest results for Nitrate-Nitrite were above the federal limit (a maximum contaminant level violation).
The utility had to notify customers about each of these violations.
Where the water comes from
Okarche draws water from 3 wells.
Annual water quality report
Okarche must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.
Where the state allows it, systems serving fewer than 10,000 people may publish the report in a local newspaper or news site instead of mailing it, and must provide a copy on request.
