Harmful Algal Blooms on New York Waterways: Protecting Health and Keeping Swimmers Safe

New York state health officials are warning swimmers and boaters about the dangers of Harmful Algal Blooms (HAB) that can occur in lakes, ponds, and streams. These blooms can be harmful to both people and pets, causing symptoms like diarrhea, nausea, vomiting, or throat irritation.

HABs are made up of visible patches of cyanobacteria, also known as blue-green algae, which are naturally present in most aquatic systems. These blooms can turn the water green and form a thick scum on the surface. The Livingston County Department of Health recently issued a Harmful Algal Bloom Advisory for Conesus Lake, which remains in effect. While the public water supply is safe for drinking, some of the blooms may produce toxins that can be dangerous if ingested.

The formation of HABs is influenced by several factors such as nutrients in the water, warm temperatures, and calm winds. Efforts are being made to control outbreaks of HABs by reducing phosphorous and nitrogen from running off into bodies of water from farms and sewer systems. By addressing these contributing factors, steps can be taken to minimize the extent of Harmful Algal Blooms and protect public health. It is important for swimmers and boaters to be aware of the potential dangers posed by these blooms and take precautions when enjoying time on the water.
