As part of the Canadian Great Lakes Action Plan, the transport and effect of non-point source agricultural contaminants in wetlands were evaluated. Due to the broad scope of this study, the abilities of many individuals with different domains of expertise were employed. Stages of the study reported here include: 1) Survey of cropping and pesticide/fertilizer practices of farms in the selected watersheds; 2) Sampling and analysis of creek water and sediments for pesticides and other parameters; 3) Study of the reversible "loss" of pesticides by adsorptive and diffusive interaction with sediment particles; 4) Investigation of the effect of the agricultural contaminants on macrophytes and invertebrates. Among the findings of this work were the detection of some pesticides years after their last use as well as the presence of microorganisms, in all creek sediments tested, capable of rapidly and completely mineralizing atrazine.
