Dissolved Oxygen Demand at the Sediment-Water Interface in Monongalia Lake, Minnesota

The objective of this study is to determine the sediment oxygen demand in Monongalia Lake. The measurements will be utilized in designing a cost~effective aeration system at the New London Mill Ponds. The activities outlined below were conducted at the Saint Anthony Falls Laboratory, University of Minnesota: 1.) Determining the chemical composition of sediments at the sediment~water interface; 2.) Sampling 3~5 sediment cores in the field at representative locations within the New London Mill Pond/lower Monongalia Lake area; 3.) Determining the Sediment Oxygen Demand (SOD) of core samples using appropriate techniques under controlled laboratory conditions; 4.) Providing summary information to be used by another investigator for a cost-effective aeration design at the New London Mill Pond.
