This Week in EPA Science
By Kacey Fitzpatrick
For most of the U.S., access to clean drinking water is as easy as turning on the faucet. In fact, a lot of hard work has gone into making sure our waterways are healthy and the water we drink is safe. Forty years ago, Congress passed Safe Drinking Water Act and since then EPA has contributed an incredibly vast amount of research to protecting human health by safeguarding the nation’s public drinking water supply—you might say it’s an ocean’s worth.
We and others highlighted a lot of water-related EPA research this past week. And an EPA-grantee was named a recipient of a MacArthur Foundation “Genius” awardee! Below is this week’s “EPA research recap.”
- Prescription for Trouble? Studying Pharmaceuticals in Wastewater.
Due to human excretion and people flushing unused pills, pharmaceuticals can end up in the wastewater stream, presenting a challenge to the nation’s wastewater treatment plants. EPA researchers are studying pharmaceuticals in wastewater to help protect the nation’s waterways. Researchers designed a model to estimate potential concentrations of active pharmaceuticals in treated wastewater. Read more.
- Tri, Tri, Tri Again for Clean Water
Recently, the Washington DC area experienced storms and heavy rainfall that caused a combined sewer overflow and sent a mixture of sewage and stormwater into the Potomac River. This caused the swim portion of the Nation’s Triathlon to be canceled due to unsafe water quality. EPA works to promote green infrastructure practices to help minimize and prevent stormwater events that can threaten public health, all while protecting the quality of rivers, streams, and lakes.

- EPA engineer led effort to reduce wastewater pollution along the Arizona-Mexican border
Raw and partially treated sewage has flowed persistently for years across the border from Nogales, Mexico into neighboring Nogales, Arizona. Through a decade of hard work, Thomas Konner, an EPA engineer, was instrumental in leading the U.S. effort to upgrade the wastewater infrastructure along the border and greatly improve the water quality and the environment.

- Green Island and the Hyporheic Zone: Why Restoration matters
Large river floodplains present diverse benefits to communities, yet management strategies often fail to consider the broad suite of ecosystem services provided by these systems. EPA is evaluating the benefits associated with restoring large river floodplains, specifically levee setback and revetment removal. This effort will provide scientific support for community-based environmental decision making and support restoration efforts. Read more.
- Detection of Silver Nanoparticles in Vadose Zone Environments
Use of nanoparticles is quickly increasing within the global marketplace as a result of their beneficial use in science, medicine, engineering and technology.However, very little is known about the effects that the increased and widespread use could have on the environment. EPA and Oklahoma State University have partnered to research and determine the effects. Read more.
- EPA Grantee Tami Bond Named 2014 MacArthur Fellow
The University of Illinois professor did a comprehensive study of how human-produced soot (black carbon) is affecting the atmosphere, illuminating how it is one of the leading contributors to climate change and standardizing how researchers measure and describe it. Bond received her first EPA “Science to Achieve Results” (STAR) grant in 2003, and currently has two other projects supported by the program. Read more.
Looking forward, next week is “Climate Action Week” and we’ll be featuring how EPA researchers are working to support taking action on climate change.
