| Coal-tar based pavement sealant is the leading source of polycyclic aromatic hydrocarbons (PAHs) in 40 urban lakes spanning the nation, according to research from the U.S. Geological Survey published this month. PAHs are a group of more than 100 chemicals that are produced when coal, oil and gas, garbage, or other organic substances..

Cleanup plan not enough to control Lake Okeechobee phosphorus, say conservation groups
| Lake Okeechobee, Florida’s largest freshwater lake and the critical water supply for the Everglades ecosystem, receives more than 500 metric tons of phosphorus per year. A new cleanup plan aims to reduce that influx, but Audubon of Florida says it won’t be enough. Florida pollution-reduction standards require the lake’s yearly..

Ohio farmers export tons of manure using federal dollars
| The intense blue-green algal blooms that overran Ohio’s Grand Lake St. Marys this summer have largely been blamed on manure runoff from surrounding fields. As a response, an incentive program offered by the U.S. Department of Agriculture is helping livestock farmers ship thousands of tons of animal waste out of the watershed. Since..

Climate change could worsen Ohio’s blue-green algae problem, increase floods
| Shift in precipitation patterns caused by climate change could pose a unique threat to central Ohio, according to new research from the University of Dayton. Geology professor Shuang-Ye Wu’s investigation indicates that summers will become drier in Ohio’s Miami Valley but precipitation will increase in the spring, which could..
