Civil Engineering iron oxidizing bacteria pigment catalytic effects oxidation rates Abandoned and underground mines have been the known source of a persistent pollutant known as acid mine drainage. Coalmines are abundant in the Appalachian area, which results in multiple heavily polluted streams and waterways. The iron leached from the mines coats the streambeds with a thick orange slurry destroying the aquatic habitat. Specifically, for this research, the Sunday and Raccoon Creek watershed were investigated.The objective of this thesis was to manipulate the environment in order to optimize the growth and catalytic oxidation effects of locally collected iron oxidizing bacteria during the production of a viable iron oxide pigment. Temperature and pH of the environments were controlled to find prime conditions for the bacteria to thrive. While it was found that the pigment created in the lab had minimal hiding power and did not form goethite, the iron oxidized with bacteria oxidized at rates averaging at least 30 times faster than those without at all pH values. Through statistical comparison, it was found that all seeps oxidized iron at a faster rate than the sterile control at a confidence value of 95%. While there was no statistical difference found between the Carbondale Seep’s oxidations rates, both were found to have the faster oxidation rates then Batgate. All oxidation rates were found to be significantly faster at the higher temperature and high pH. The failure in the production of goethite was found to be a consequence of the overabundance of sulfate within the tanks, estimated at least 6 times the concentration at the seeps. 2017-09-19 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou149383043673114 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou149383043673114 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
