4.4.2.5 Data Uses
The in-drain sediment data will provide indication of any trends with respect to accumulation or depletion of selenium in the sediments, as well as distribution within the sediments. Coupled with water quality data from the inlet and outlet (A and B) stations, the sediment data will also help to indicate fate of selenium within the Drain. In addition, a single core of the entire sediment profile will be analyzed to compare selenium sediment levels in the SLD with the hazardous waste criterion level of 100 ppm to provide indication of the need for management action should the levels be increasing.
