The USGS is initiating a 5-year study, in cooperation
with the Lake Champlain Basin Program, to determine the role of
land use and stream hydrology on the mobility of mercury and methyl-mercury
in the Lake Champlain Basin. Research will focus on developing a
mercury mass balance for the Lake Champlain Basin, determining mercury
methylation potential as a function of upstream land use, understanding
mercury dynamics during high-flow events, and other controls on
mercury transfers from the basin to the Lake.
Any linkages between mercury mobility and land-use
practices will be used to identify potential approaches to the management
of mercury contamination. The investigation will include synoptic
sampling of tributary stream sediments, synoptic snowmelt surveys
of stream waters, fixed-site stream monitoring, and intensive watershed
investigations for targeted land uses.
