This U.S. Geological Survey (USGS) Data Release provides analytical data from samples and measurements completed at the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota (Site) between 1984 and 2010. Included are inorganic and organic chemistry data from water, oil, and...
Comparative Study of Organic Degradation in Selected Hydrologic Environments
Degradation of organic material produces organic compounds that both alter the quality of water and affect the inorganic reactions. The hydrogeologic controls on organic-inorganic reactions, their rate, and progress are not well understood. This project focuses on the occurrence and fate of organic compounds in (1) contaminant aquifers, (2) soils, and (3) lake sediments. Project objectives are to increase our understanding of reactions involving organic matter and to evaluate the significance of these reactions in geochemical studies. Of particular interest are: identifying organic and inorganic compounds that are present as a result of the degradation of organic material; studying the interaction of organic compounds...

This USGS data release includes all the data presented in peer-reviewed publication entitled "Degradation of MCHM (4-methylcyclohexanemethanol) in Sediments from Elk River, West Virginia". We conducted experiments on crude MCHM to examine photooxidation or biodegradation. We also assessed the potential of sediments to serve as a long-term source of MCHM and well as the potential for native microbial communities to catalyze the anaerobic breakdown of MCHM. We developed a quantitative method to measure the 2 isomers (cis- and trans-) of 4-MCHM, using solid phase micro-extraction (SPME), which had a minimum detection limit of 5 µg/L. The data release shows that the abiotic degradation experiments showed no evidence...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
