In 1969, the Cuyahoga River near Cleveland was so polluted that it caught fire, helping to launch the modern environmental movement and prompting Congress to pass the Clean Water Act three years later.
In 1969, the Cuyahoga River near Cleveland was so polluted that it caught fire, helping to launch the modern environmental movement and prompting Congress to pass the Clean Water Act three years later. It was one of the first laws to safeguard waterways and set national water quality standards.
While the Clean Water Act successfully regulated many obvious causes of pollution, such as the dumping of wastewater, it’s done less to limit more diffuse types of pollution, such as “nonpoint source pollution” that includes agricultural runoff from fields and urban stormwater from buildings, paved surfaces and yards — says a new study from University of Missouri researchers.
Though hard to see, nonpoint source pollution has become one of the main environmental threats to drinking water across the country, said MU researchers who are offering strategies to address the problem.
“Large amounts of nitrates and nitrites, such as those found in fertilizer, can cause negative health effects such as blue baby syndrome,” said Robin Rotman, assistant professor in the MU School of Natural Resources, who led the study. Rotman also holds courtesy appointments in the MU School of Law and the MU College of Engineering. “Nonpoint source pollution can lead to toxic algae blooms; pesticides and herbicides also contain carcinogens that can threaten human health," she said.
