Bacteria and Nitrate Monitoring

With help from volunteers, PRWC continued monitoring local rivers for E. coli bacteria and nitrate as prioritized in the Watershed Based Plan. These stream assessments help evaluate current conditions as well as success of remediation and restoration activities, provide input for management tools, and support scientifically-based decisions for water quality.

Overall, PRWC has observed bacteria levels that support safe recreation in dry weather conditions and higher bacteria levels after rain events. People interested in swimming, wading, and boating are encouraged to wait at least 48 hours after a rain event for bacteria levels to come down before enjoying water-based recreational activities.

Stream monitoring data are available for viewing through an online interactive map.
