Findings come as EPA edges toward final new clean water rule

Geographically isolated wetlands like prairie potholes and desert playas in the Southwest are critical to water quality and also provide many other ecosystem services — even though they may lack the regulatory protections of other wetlands, according to Indiana University researchers.
Continued loss of such wetlands is likely “to cause serious harm to North American waters,” according to John M. Marton, a researcher with the IU Bloomington School of Public and Environmental Affairs.
“Geographically isolated wetlands provide important benefits such as sediment and carbon retention, nutrient transformation and water-quality improvement, all of which are critical for maintaining water quality,” Marton said, discussing the conclusions of a new article appearing in BioScience.
