Hutchinson, Ph.D. Vice President for Research and Public Services ATTAC@dNTS Exhibition A Research Proposal -z - incineration, landfilling, and utilization. Utilization is the Only _ alternative which does not waste the potential value of this material_. In '. addition, recent shortages and increased costs of commercial fertilizers have created a higher degree of interest in the utilization of less expensive farms of fertilizer materials such as sewage sludge. Farmers and local residents need to be told of the potential value of this urban waste and how to best utilize it to the maximum extent possible. Potential markets need to. be identified. The general public must. be given assurances that utilization of compostedsludge is safe and environmentally sound. - 'Scope of Work: The City of Bangor in cooperation with the U.S. Environmental Protection Agency and the U.S. Department of Agriculture, Agricultural Research Service intends to demonstrate the technical and economic feasibility of com- posting raw municipal sewage sludge by high rate suction aeration techniques under the harsh climatic conditions experiencedin the northern states. To accomplish this task, the city is well equipped to test and engineer the operational aspects of the proposed composting process, however it must rely heavily upon the expertise of the Agricultural Research Service, USDA and the University of Maine to satisfy the technical and scientific portions of the proposed demonstration.. The proposed services to be performed by. the Agricultural Research Service and Maine Life Sciences and Agriculture Experiment Station through a restricted account will include the following: A. Consultant Services - Provide the expertise necessary to furnish technical advice throughout the demonstration project. To interpret the day to day data. specifically the temperature and oxygen status, so that the composting process is maximized.To evaluate the effects of -3 - various bulking materials and the ratios of bulking agents to sewage sludge. To determine the relative degree of pathogen kill by high rate thermophillic composting of raw dewatered sewage sludge by suction, aeration under a range of climate conditions. B. Analytical Services - Provide the direction and responsibility for obtaining analyses of both sludge and compost for Hg, Cu. Ni, Zn, Pb, Cu, N, P, pH, Ascaris, Salmonella and Fecal Coliforms during the demonstration period. Plant tissue analysis shall be performed as part of the crop evaluation assessment. C. Utilization of Compost on the Land - The primary research objective of this study is to evaluate poten- tial uses of the product as a fertilizer (source of, nutrients), as a soil amendment for improvement of the organic content and as a material to improve the water holding characteristics of the soil. The evaluation shall consider types of crops and rates of applica- tion for specific uses. Some specific uses to tie evaluated are: - a. Establishment of turf -road banks, highway cuts,. areasof subsoil and lawns. b. Topdressing turf c. Land reclamation - gravel pits and quarries d. Cropland Other uses include: a. Nursery products b. Erosion control c. Forestry - -4- d. Construction e. Many others D. Summary Report - Provide the city with a report including'a compilation of the data collected based upon a chronology of events. a recommendation for future composting of sewage sludge, a recommendation for the long term utilization of the compost material and other significant Information obtained during the project. -11131141 .Analysis - Sludge $ 600 Analysis - Compost - 600 Analysis - Plant tissue 800 Consultant services and land use evaluation 1.149 Total Direct Cost $3,149 Indirect Costs (27.04%) 851 TOTAL $4,000 -5- Responsoble researchers: 1.
