Dickey-Lincoln School Lakes Project

Sediment mercury concentrations higher than levels normall y considered trace or background were encountered up to 80 cm belo w the sediment-water interface in samples obtained from four oligotrophi c lakes in northern Maine . These lakes are in three different watershed s and are as far as 65 km apart . The values reported are far lower than levels reported elsewhere from contaminated sites . The distributio n and magnitude of the sediment concentrations encountered suggest long-ter m diffuse mercury inputs to the lakes from the watersheds . In addition , concentrations up to twice as high in near-surface …
