A specific ultraviolet absorbance pilot project in Adirondack Mountain lakes and streams

Specific ultraviolet absorbance at 254 nm (SUVA254) has been proposed to be an indicator of mercury (Hg) methylation potential in aquatic ecosystems, and there have been numerous efforts to measure SUVA254 in streams in different watersheds of the US. In the Adirondack Mountain region of northern New York, long-term monitoring has primarily focused on lakes, and to date there have been few if any measurements of SUVA254 in lakes in this region. From August 2013 through July 2015, the New York State Department of Environmental Conservation (NYSDEC) and Adirondack Lakes Survey Corporation (ALSC) measured SUVA254 in >1800 lake and stream samples. Here we describe the complete pilot data set, which includes routine acid/base chemical parameters and Hg concentrations in select Adirondack surface waters. These data can be made available upon request.
