U.S. EPA Issues Health Advisory Values for Algal Toxins in Drinking Water

The U.S. EPA has issued health advisory values for algal toxins in tap water that are protective of human health based on the best available science. EPA has also recommended how utilities can monitor and treat drinking water for algal toxins and notify the public if drinking water exceeds protective levels. Health advisories are not regulations, but they provide technical guidance to help state and local officials and managers of water systems protect public health.

EPA Creating an Early Warning System to Detect Harmful Algal Blooms

EPA has announced that it is developing an early warning indicator system using historical and current satellite data to detect algal blooms. EPA researchers will develop a mobile app to inform water quality managers of changes in water quality using satellite data on cyanobacteria algal blooms from three partnering agencies – NASA, NOAA, and the U.S. Geological Survey. The multi-agency project will create a reliable, standard method for identifying cyanobacteria blooms in U.S. freshwater lakes and reservoirs using ocean color satellite data.

U.S. EPA Awards Grants to Target Lake Erie Hamful Algal Blooms

U.S. EPA announced the award of four Great Lakes Restoration Initiative grants totaling over $8.6 million to Ohio, Michigan and Indiana state agencies to protect public health by targeting harmful algal blooms in western Lake Erie. “In the wake of the Toledo-area drinking water ban, EPA quickly convened a meeting with state and federal agencies to identify their most immediate funding needs to reduce pollutants that contribute to harmful algae in western Lake Erie,” U.S. EPA Region 5 Administrator/Great Lakes National Program Manager Susan Hedman said.
