Road salt is as a significant source of pollution in the Lake Champlain Basin, which includes 11 sub-basins drained from major tributaries in New York, Vermont, and Quebec including the Saranac, Ausable, Winooski, Missisquoi, and Lamoille Rivers. With the generous support of the LCBP, AWI scientists will compile existing data from all water bodies within the Lake Champlain Basin to determine what is driving sodium and chloride levels. As a result, scientists will have a better understanding of the extent and cause of road salt pollution in the basin, which will help inform long-term practices to reduce road salt and protect the environment.
“We look forward to working with LCBP to understand long-term changes, their causes, and the trajectory of sodium and chloride concentrations in the Lake Champlain Basin,” said Dr. Brendan Wiltse, senior research scientist for AWI and Principal Investigator for both grants. “As a result, New York and Vermont decision makers will be better informed to make management decisions that benefit the environment and the public.”
Clean Water Act turns 50
Fifty years ago this week, federal lawmakers overrode a presidential veto to enact the Clean Water Act, a landmark law for the nation’s water quality.
The iconic image of the Cuyahoga River on fire in Ohio spurred congressional action and ushered in a half century of major river restorations across the nation. The goals outlined in the act included restoring the country’s water to a “fishable and swimmable” state.
The law imposed new permitting requirements on polluting industries and sewage treatment plants, but it failed to address diffuse pollution from storm and agricultural runoff, the largest source of pollution in many parts of the country. The standards adopted under the law in many places are now decades old or unable to address emerging problems.
