Background Water Quality

To more adequately protect receiving water bodies, government policy is leading toward adaptation of integrated management approaches that protect the integrity of the ecosystem as a whole. Approaching natural water quality is a goal of integrated water resource management. Ecoregions represent geographical areas of relatively similar land surface form, mineral availability, natural vegetation and land uses, and therefore, represent areas of relatively similar background water quality. Water quality at relatively unimpacted reference locations is representative of regional natural water quality and may be reasonably extrapolated to other similar locations within the ecoregion. These concepts were applied to the Southeastern Wisconsin Till Plains ecoregion and the Milwaukee River, Wisconsin.

Silver Release

An environmentally friendly technique was used to produce levan-capped silver nanoparticles of about 30 nm (with a loading of 30%) that showed bactericide effect, for E. coli and B. subtilis. That effect was mathematically studied with a dose-response model (lethal dose of 12.4 ppm and 6.8 ppm respectively). These silver nanoparticles were subsequently introduced in a gel to create a silver release system with bacteria inhibition activity. Silver release from the gel and its bactericidal activity was theoretically studied to develop a unique model that is able to predict accurately both silver release and lethal dose for any type of bacteria. This model will be useful for performing predictions for future silver in gel applications.
