Understanding Water Quality Results

Riverside Public Utilities reports laboratory results, regulated contaminant levels, and sampling schedules in its annual report and water quality webpages. Results list measured values, applicable federal and state Maximum Contaminant Levels (MCLs), and public-notification items where a limit is exceeded. For the most recent Consumer Confidence Report and monitoring details, consult the City of Riverside Public Utilities water quality pages City water quality reports[1].

Look for the table of regulated contaminants and the column showing MCLs to compare measured values.
