The award will be used to combat algal blooms which have been a consistent issue in bodies of water, due to changes in water temperature, as well as heavy rainfall and nutrient runoff.

The EPA wants to merge the Office of the Science Advisor with the Office of Science Policy, which would give it less authority.
