EPA's CyAN Mobile App Provides Early Detection of Algal Blooms in U.S. Freshwater Systems

The CyAN App is a mobile application that uses satellite data to map the location of harmful algal blooms in waters across the US. The app provides weekly information about cyanobacteria concentrations in many of the largest water bodies in the country. This information can be used to inform decisions regarding recreational and drinking water safety. The CyAN App is designed for use on Android™ devices and is available for download on Google Play™.

This webinar will provide a general overview of the app including what it is used for, why and how it was developed, and who it was designed for, as well as state case studies from their beta testing of the CyAN app.
