St. Louis River AOC and reference water quality monitoring (CAP_11_2011)


This study will facilitate study of the St. Louis River Area of Concern by collecting and analyzing samples within the AOC as well as sites outside the AOC. The sites outside the AOC will be used for comparative purposes. Three sites are in the AOC 8 sites are outside the AOC. All of the sites, with the exception of the one near Outer Island, were sampled in 2010 as part of the EPA National Coastal Condition Assessment. The 3 sites in the AOC as well as 5 other sites have previously been sampled by DNR personnel. The samples will be collected during a week in August. At each site profiles of temperature, DO, pH, light extinction (PAR), and conductivity will be collected along with Secchi depth and samples for nutrients and chlorophyll. The latter analyses would be conducted at the State Lab of Hygiene. Plankton (phyto and zoos) would also be collected and analyzed at the Science Operations Center. Data analysis will include comparisons with concentrations measured in previous years at the sites as well a comparison of concentrations at sites within the AOC with concentrations at sites located outside the AOC.


Collect water quality information from within the St. Louis AOC and from reference sites outside the AOC for the purpose of evaluating the relative impairment of some water quality parameters within the AOC


Quarterly and final reports to include data summaries, spatial and temporal comparisons, and conclusions related to the relative impairment of the St. Louis AOC.

Final report. “In 2011 this study collected and analyzed selected water quality data within the AOC as well as other sites in the nearshore area in the Wisconsin portion of Lake Superior. The results are compared between the AOC and non-AOC sites as well as data collected in 2010 as similar sites.”
