HAB Response and Program Integration

• PWS HAB Rules (OAC 3745-90) specify compliance monitoring and treatment techniques – HAB Treatment Optimization and HAB

General Plan

• Drinking Water Beneficial Use Assessment

• Source Water Protection Plan • 9-Element Plan and Section 319 Grants

Monitoring Tools and Training

• Water quality monitoring and analytical equipment

• HAB response and technicalassistance

• Satellite imagery • Phytoplankton identification
