NARRAGANSETT, R.I., Dec. 17, 2014—A chemical oceanographer at the University of Rhode Island who measured organic pollutants in the air and water around Lake Erie and Lake Ontario has found that airborne emissions are no longer the primary cause of the lakes’ contamination. Instead, most of the lakes’ chemical pollutants come from sources on land
