Our scientific objectives are: (1) the assessment of the link between historic and current extreme weather events and water quality indicators using satellite and field work data, including water color, temperature, turbidity, precipitation, water level, and ice/snow/flood extents; (2) improved understanding of the links between extreme weather events and the source and finished water quality including cyanobacteria densities, cyanotoxins, DBPs, and nutrient concentrations; and (3) the modeling and prediction of adverse impacts to source and finished water to understand the future impact of climate-change induced extreme weather events on water safety in Lake Erie.

Progress Summary:

We initiated an innovative interdisciplinary approach using historic and current satellite remote sensing and geodetic data, molecular microbiology tools for comprehensive understanding cyanobacterial dynamics and its influence on drinking water quality in Lake Erie region. During the third project year, we performed two main tasks: (1) we analyzed historical data (from 2002 to 2012) of harmful algal blooms (HABs) in Lake Erie in order to examine temporal variability and environmental drivers; (2) we performed laboratory measurements of the collected water samples (toxin, DBPs, molecular detection of toxin-producing cyanobacteria, etc) and satellite images of the source water in Lake Erie; and (3) we conducted extensive statistical analyses of the collected parameters. 

Future Activities:
