Harmful algal blooms can cause big problems in coastal areas and lakes across the United States. When toxin-containing aquatic organisms multiply and form a bloom, it can sicken people and pets, contaminate drinking water, and force closures at boating and swimming sites.

With limited resources to monitor these often-unpredictable blooms, water managers are turning to new technologies from NASA and its partners to detect and keep track of potential hazards. This is particularly critical in lakes and reservoirs that people use for both recreation and water supply.
