This water must therefore be treated with disinfectant in order to be safe to drink. However, some disinfectants react with naturally-occurring materials in the water to form byproducts that are associated with health risks.

EPA environmental engineer Michael Finn will review the Disinfectants and Disinfection Byproducts Rule, a series of regulations aimed at limiting public exposure to these disinfectant byproducts. Jolyn Leslie, a regional engineer for the Washington State Department of Health Office of Drinking Water, will discuss the challenges for small systems dealing with disinfectant byproducts in Washington State and the possible solutions.

Bonus—attendees may have the option of receiving a certificate for participating in this webinar. Register now!

This Week in EPA Science

By Kacey Fitzpatrick

Research Recap graphic identifierWas your team already knocked out of March Madness? Then you must have plenty of time to catch up on the latest in EPA science. And if they’re still in it, there’s always halftime!

Women’s History Month
March is Women’s History month and this year’s theme is “Working to Form a More Perfect Union: Honoring Women in Public Service and Government.” Here at EPA, there are quite a few women scientists and engineers who truly are helping us achieve a more perfect union. We asked some of them to share a few words about what inspired them to pursue a career in science. Read what they said in the blog Women’s History Month: Honoring EPA Women in Science.

Water Reuse and Conservation Research
In honor of World Water Day this week, the White House held a water summit to raise awareness about water issues and potential solutions in the US, and to catalyze ideas and actions to help build a sustainable and secure water future through innovative science and technology. In conjunction with the summit, EPA announced $3.3 million in funding to support water reuse and conservation research. “The research announced today will help us manage and make efficient use of the water supply in the long term,” said Thomas A. Burke, EPA Science Advisor and Deputy Assistant Administrator for our Office of Research and Development. Read more about the grants in this press release.

EPA’s Student Competition Lights the Way
A former team that competed in EPA’s People, Prosperity and the Planet (P3) student design competition was just named one of the most innovative companies of 2016 by Fast Company Magazine. The P3 team from the University of Illinois at Urbana-Champaign was initially funded in 2006 with a $10,000 grant. The student lead, Patrick Walsh, leveraged that funding, research, and experience to ultimately form the company Greenlight Planet. Patrick Walsh was also named to the 30 under 30 list by Forbes Magazine in 2012. Read more about EPA’s P3 student design competition.

Homeland Security Research
EPA’s Gregory Sayles recently wrote about a homeland security research demonstration. Along with the Department of Homeland Security, EPA researchers demonstrated a toolbox of options to mitigate and decontaminate urban, wide-area radiological contamination stemming from an event such as a dirty bomb detonation or nuclear power plant accident. Read more about the event in the article EPA and DHA Partner in Radiation Decontamination Event.

Around the Water Cooler: Keeping Stormwater In Place

By Lahne Mattas-Curry

Raining in the city

No where to run: stormwater has no place to go but the sewer.

In the first post of my series on EPA water research, I gave a little history lesson and introduced green infrastructure. This week, we’re going to focus on the cost of combined sewer systems—to our health, our environment and even our economy.

There are hundreds of cities across the country that have combined sewer systems. For example, in New York City, more than 27 billion gallons of raw sewage and polluted stormwater discharge out of 460 combined sewer overflows into the New York Harbor alone each year. Think about all the impermeable surfaces in the city: sidewalks, streets, roofs, patios. It’s a concrete jungle.

To manage stormwater—and set up scenarios to see the impact of development—EPA scientists are developing the Stormwater Calculator that estimates the annual amount of stormwater runoff from a specific site and provides city planners, developers, and property owners a way to calculate the result of specific actions on our waterways. The online tool will be available later this fall.

As stormwater flows over the surface of your property, driveways, parking lots, roofs, etc, it picks up lots of sediments, such as animal droppings, tire residue, motor oil, brake dust, deicing compounds (in the winter), fertilizers, pesticides, trash, heavy metals and other pollutants and carries them to the nearest storm drain.

Obviously, there are things that cities can do to help reduce stormwater run off, and the steep price tag that goes with the cost of separating the combined sewer systems.

For example, in Omaha, the city is testing green infrastructure throughout the city to help reduce the $1.7 billion sewer system separation project. EPA scientists are testing and monitoring soils in Omaha, and other cities such as Cleveland and Cincinnati, to measure how successful green infrastructure is at keeping the combined sewer overflows to a minimum.

City of Omaha

Cities like Omaha are looking for ways to use green infrastructure to reduce stormwater costs.

There are steps you can take too.

According to the University of Nebraska, for every 1,000 square feet of impermeable surface on your property, every 1 inch of rainfall generates approximately 626 gallons of water. If you add two 55 gallon rain barrels to your property, you now have water to irrigate your gardens. Add a rain garden, and you probably take care of much of the excess. Now, rain is absorbed back into our aquifers instead of rushing into the nearest storm drain, keeping waterways clean and ecosystems functioning.

Many states and counties subsidize the installation of green infrastructure on property, so check with your county and state government. It’s worth it to make sure we have clean water for generations to come.

Around the Water Cooler: Leaving the Outhouse Behind

By Lahne Mattas-Curry

Stormwater flows from a large pipe.

Green infrastructure helps keep stormwater in place.

This week, and every Thursday that follows, I’ll introduce you to the EPA scientists and engineers who work to make sure our water stays clean and that we have enough for generations to come.

Today I’m kicking off a series on green infrastructure while we recognize the role of science and innovation in the Clean Water Act, which turns 40 this year.

What is green infrastructure? It’s actually just a fancy term for rain gardens, rain barrels and cisterns that keep excess water out of our storm drains.

But let’s start with some history. In the mid-1800s, flush toilets came to America. Everyone wanted one so that no one would have to make that nightly cold, dark trek to the outhouse. Soon, though, it became obvious that when you “flush” the toilet inside the nice warm house, the waste has to go somewhere. Initially that somewhere was our streets.

Thankfully, that did not last long.

Motivated by smelly city streets, municipalities added underground pipes to carry the wastewater from homes and businesses and deposit in waterways where it could be diluted and carried away in the current. The pipes, though, also carry stormwater that rushes off the streets during heavy rain.

Welcome to the combined sewer system.

There are approximately 800 cities and towns across America that still use combined sewer systems, including big ones such as New York and Chicago, and smaller ones like Omaha and Louisville.

Today, these systems don’t feed directly into our waterways. The water is first sent to a treatment plant where it is cleaned.

The problem with these combined sewer systems is that when it rains hard, the polluted wastewater doesn’t always make it to the treatment facility, and instead goes directly to our rivers, streams and other waterways. (A violation of the Clean Water Act. And also pretty gross.)

But changing out all these networks of pipes—called gray infrastructure—is costly. EPA scientists and engineers have been working with several municipalities around the country to find alternatives—innovative solutions to efficiently and inexpensively reduce runoff flowing into combined sewer systems.

Each Thursday over the next few weeks I’ll highlight green infrastructure research and best practices while sharing ways you can make a difference in your community.

In the meantime, check out this interactive tool from the Arbor Day Foundation to compare the difference between a community with increased green infrastructure in the form of more trees versus a community with less. Which would you rather live in?
