Got questions about how nutrient pollution affects our water? Join EPA scientist Anne Rea and other Agency experts today at 2:00 pm (ET).

To get you started and introduce you to Anne, we’ve asked her to answer a few questions.

What is your educational background?
I have a Ph.D. in Environmental Health Sciences from the University of Michigan. I studied the biogeochemical cycling of mercury and trace elements in forested ecosystems. Since little work existed in the mercury realm, most of the literature and experts I worked with focused on nitrogen pollution.

How did you become interested in nutrient pollution?
After joining EPA, I wanted to work on the ecological side of things (versus human health) and spent several years doing ecological risk assessments. I then led a joint review of two air pollutants, nitrogen dioxide and sulfur dioxide, for the National Ambient Air Quality Standards. This was the first time two pollutants were reviewed together, and the first time a “secondary” (public welfare) standard was separated from the “primary” standard (human health effects). I’ve always worked on multi-pollutant, multi-media problems, so was uniquely suited to lead the risk assessment for that review.

What’s the most interesting thing you have learned trying to solve this problem?
The dedication and commitment of staff across EPA is amazing. This is one problem the Agency is uniquely suited to solving from a scientific and regulatory perspective—but we can only do it together—across offices, regions and research programs in the Agency, and in collaboration with the states and other federal partners.

How can technology and innovation help solve the problem?
We’ve struggled to solve this problem for more than 40 years, and I think as an Agency we’ve made some progress. As the world’s population increases, there is a demand for increased food production and increased energy use—all of which releases nitrogen (and sometimes phosphorus, sulfur, and carbon) into the environment.

We are working across the Federal government to develop a ‘nutrients challenge’ which will challenge teams globally to come up with innovative ideas to reduce nutrients—either from the emissions source or from the waste stream.

We know we can’t solve nutrient pollution alone. What other federal agencies are we partnering with?
We are working with the National Oceanic and Atmospheric Administration (NOAA) the U.S. Geologic Survey (USGS), the U.S. Department of Agriculture (USDA) the U.S. Fish and Wildlife Service (FWS), the National Park Service (NPS), and others, through jointly funded research, collaborations, cooperative agreements, etc. We work hard to share and use each others data and models as we work collectively to make an impact on nutrient pollution for the country.
