GEMS: Great Environmental Moments in Science

Keeping Beaches Safe… with Statistics!
EPA researchers and partners are creating tools to help beach managers protect public health.

Into the Dead Zone
EPA researchers are creating a state-of-the-art three-dimensional model of the Gulf of Mexico's dead zone.
Beneath the Surface
Glider surfs underneath the ocean, delivering new data about coastal waters.

Why Study Green Infrastructure?
EPA scientists and engineers are exploring how to tap green, effective, and low-cost methods to improve stormwater management.

Stormwater Calculator to Manage Rainfall Runoff
A new tool developed by EPA allows planners and property owners to assess how green infrastructure can be used to reduce rainwater runoff from development sites.
Helping Cities Benefit from Green Infrastructure
EPA provides research and guidance on the incorporation of green infrastructure into Omaha’s combined sewer overflow control plan.

Showing Buried Streams the Daylight
Researchers compare the effectiveness of buried streams versus open-air streams for removing harmful nitrogen from water systems.
Public Database Helps Users Provide Clean Drinking Water
EPA’s Drinking Water Treatability Database provides a one-stop shop for information on contaminants and treatment options.
New Ballast Water Protocols Designed to Stop Invasive Species
EPA Partners with Coast Guard to Develop Ship Treatment System Protocols.
