Harmful Algal Bloom (HAB) Monitoring
Public water systems with a surface water source(s) must comply with HAB monitoring and reporting rule requirements (OAC 3745-90-03). Public water systems may be eligible for reduced monitoring, based on cyanotoxin occurrence and treatment capability. Please click the links, below, to view the HAB monitoring schedule assignments for each public water system, HAB monitoring requirements by schedule , and HAB sampling triggers and implementation guidance.

2020 HAB OFF-SEASONAL MONITORING: MICROCYSTINS AND CYANOBACTERIA SCREENING (QPCR) SAMPLING
Schedule 1 and 2: If your PWS has elected to sample qPCR, PWSs will collect their first biweekly qPCR sample the week of November 1, 2020. If you have not elected to sample for qPCR, you will collect your first biweekly raw water microcystins sample the week of November 8, 2020. Cyanobacteria screening or raw water microcystins samples must be collected on alternating weeks thereafter.
Schedule 3: PWSs must collect a monthly qPCR sample beginning November 1, 2020.
Schedule 4: PWSs must collect a biweekly finished water microcystins sample beginning November 8, 2020.
If you are a system that does not qualify for reduced monitoring, please continue weekly monitoring for microcystins at both raw and finished sampling points.
