EPA researchers are investigating ways to protect children from lead exposure.
-
Groundwater: Understanding and Protecting Our Hidden Resource
Groundwater provides about half of the drinking water supply worldwide. To protect this valuable resource, EPA researchers study how water is transported through the subsurface and how contaminants can move underground.
-
Preventing Algal Blooms with a “Pinch of Sugar”
EPA researchers are looking at ways to inhibit the development of algae that can produce cyanobacterial harmful algal blooms. One method they are studying is adding a food source to water that would allow other bacteria to better compete.
