Through an Interservice Agreement with the Air Force, the Environmental Sanitation Section (ESS) of the Arctic Health Research Center (AHRC) has prepared design criteria for the construction of an experimental anaerobic pond followed in series by an aerobic pond for treating sewage from the Base. Because of the annual 6-month period of ice cover in this locale, the anaerobic pond has been designed large enough to store the entire winter sewage flow of 12 million gallons. During the summer months the stored sewage will be fed into the aerobic pond for a 10-day retention period with subsequent discharge. It is hypothesized that the almost continual summer sunlight will greatly increase algal action and satisfaction of Biological Oxygen Demand (BOD), resulting in adequate treatment with a shorter detention time and higher BOD loadings than are generally used. ESS will monitor the operation of the pond upon its completion to determine operating efficiencies, optimum loading and bacterial and chemical phenomena during the different seasons. Results of the study should permit establishment of more exact design criteria for future arctic sewage oxidation ponds. (Author)
