Satellite Early Warning System Identifies Algal Blooms

Data Monitors Water Color

22 Jul 2021 by Local Press Report

The US Environmental Protection Agency (USEPA) has announced the release of a new tool, CyANWeb, that can help federal, state, Tribal, and local partners identify when a harmful algal bloom (HAB) may be forming where people swim, fish, and boat. The tool uses satellite data to alert users based on specific changes in the color of the water in over 2,000 of the largest lakes and reservoirs across the United States. Cyanobacteria, also called blue-green algae, occur naturally in many water bodies. However, when they multiply, they can form potentially toxic HABs, which can increase drinking water treatment costs for communities and impact lakes and other recreational areas. CyANWeb, developed by the Cyanobacteria Assessment Network (CyAN) with input from users across the country, makes cyanobacteria satellite data more accessible to water quality managers, communities, and anyone interested in knowing more about water quality in their area.
