Ohio Environmental Protection Agency
Overview
• HAB response and program integration • Monitoring tools and training • Research efforts • Case Studies (public drinking water systems, PWS)
– Wilmington PWS: Alternative water sources – Akron PWS: Reservoir management and source water protection – Cadiz PWS: Tappan Lake Nutrient Reduction Initiative – Celina PWS: Treatment train wetlands

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
Ohio Environment Protection Agency
Monitoring Tools and Training
• Water quality monitoring and analytical equipment
• HAB response and technicalassistance
• Satellite imagery • Phytoplankton identification
and reservoir managementworkshops – Stone Lab, Lake Erie: Aug 2020 – OTCO: June 2020
– Efficacy of ultrasound/sonication (Dr. Weavers, OSU)
• Track Blooms From the Source

HAB Research Efforts
• Harmful Algal Bloom Research Initiative (HABRI, ODHE) https://ohioseagrant.osu.edu/research/collaborations/habs
– Algaecide selection and targeted application (Dr. Cutright, U Akron)
