The State of Ohio's nutrient reduction strategy documents ongoing nutrient reduction activities and identify areas where more work is needed. The primary sources of nutrient pollution are runoff of fertilizers, animal manure, sewage treatment plant discharges, storm water runoff, car and power plant emissions and failing septic tanks. Some factors that can contribute to HABs include sunlight low-water or low-flow conditions calm water warmer temperatures and excess nutrients (phosphorus or nitrogen). These cyanotoxins may affect the liver, nervous system and/or skin. Basics What is a harmful algal bloom (HAB)?Ī harmful algal bloom (HAB) is a large growth of bacteria that can produce cyanotoxins. It advises boaters that is a HAB confirmed at a beach and may be present in other areas of the lake.ĭownload Recreational Public Health Advisory Sign (PDF)įor Recreational Advisories : Current Ohio recreational water body monitoring and advisories can be found at the Ohio Department of Health's BeachGuard website.įor Drinking Water Advisories : If microcystin, anatoxin-a, cylindrospermopsin or saxitoxin is found above drinking water thresholds in the finished water of a public water system, the water system will public notice a drinking water advisory.
