Research Objectives
The central goal of this project is to understand the role that acidophilic and acidotolerant anaerobic microorganisms play in global iron and sulfur cycles. We will do this by examining the microbiological and geochemical controls on the attenuation of acidic, iron-rich and sulfate rich water. In addition, this project will serve as a site to study the effects of the participation in research studies on the learning of the nature of science and engineering. The following hypotheses will serve as a guide for the research:
I. Fe(III) and sulfate reduction occur around the perimeter of the Davis Mine area, and this is a major process for attenuating AMD from the entire site.
II. A complex community of acidophilic and acidotolerant anaerobic microorganisms, which includes Fe(III)- and sulfate-reducing bacteria, are key players in attenuation of acidity and heavy metal contamination.
III. The geochemical and microbiological processes contributing to attenuation of contamination at the Davis mine site are the same as those at other similarly impacted watersheds.
IV. Teachers who have participated in scientific research understand scientific processes and methods in a manner similar to those of experts (scientists and engineers), and this understanding is more readily transferred to their K12 students.
