Tri, Tri, Tri Again for Clean Water
By Marguerite Huber and Dustin Renwick
When athletes register for a race, they invest money, time, and energy. My fellow EPA blogger, Dustin Renwick, and I signed up to be a part of a relay team competing in the Nation’s Triathlon here in Washington, D.C.
Dustin ran the 10k, I biked the 40k, but our swimmer didn’t even get wet.
Our teammate, and all of the other athletes, did not get to participate in the swim portion of the race because it had been cancelled due to unsafe water quality.
The night before the event, the local area experienced storms and heavy rainfall that caused a combined sewer overflow that sent a mixture of sewage and stormwater into the Potomac River just north of the triathlon swim starting line.
The District Department of the Environment informed race officials of the unhealthy conditions late that evening and due to the high levels of bacteria such as E. coli, they agreed to cancel the swim.
Although boating, kayaking, and paddle boarding are allowed in the Potomac River, “primary contact recreation activities,” like swimming, have been banned in the river within the District of Columbia since 1971, when District health officials and EPA sought to protect people and publicize the health hazards of local water bodies.
Since then, clean-up efforts have resulted in a cleaner Potomac. Special swimming events, such as the Nation’s Tri, could apply for exceptions to the rule as of 2007. Event organizers are required to monitor and analyze water quality samples prior to the event and submit a contingency plan in the event the District Department of the Environment determines the river is unsafe for swimming.
Despite the progress, sewer overflows can still harm river quality. The Nation’s Triathlon had to cancel the swim in 2011 as well.
Judging by social media reactions, most athletes felt the Nation’s Tri race officials made the right choice in cancelling the swim. Safety is important, no matter how many hours of training you have put in.
But the disappointment of several thousand athletes is only a symptom. This situation really calls attention to the need for improvement in our stormwater infrastructure.
The 772 cities in the U.S. that have combined sewer systems can all be challenged by heavy rains that rush over urban impervious surfaces and into their sewers. This results in stormwater and untreated waste polluting our water bodies.
EPA has worked 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. Green infrastructure techniques such as green roofs, permeable pavement, and rain gardens help slow down runoff and help water more naturally filter out excess nutrients and other pollutants on its way into the ground.
These kinds of activities help protect human health and the environment. Hopefully one day soon, as race contestants, we can count on completing the bike, run, and swim through our nation’s capital and in similar events across the country.
