With the increasing number of stabilization ponds, it becomes desirable that they be located where they will least affect the present and future uses of water, cause the least amount of nuisances, and be economical with respect to location and construction. These desirable characteristics cannot always be fulfilled and thus a compromise must be made when choosing the site of the pond. At present there is no conventional method for evaluating various site characteristics and construction practices of areas or sites where wastes are released to the ground. Studies have been conducted on various phases or areas relating to stabilization ponds including the theory of treatment, ·and the degree of treatment. From various earlier studies of stabilization ponds, suggested design criteria have been developed. Previous site selection has in a large number of cases been limited by economical considerations or the lack of detailed study by the designer. Partially because of the limited site evaluation, problems have occurred. The problems have ranged from odors and mosquito nuisance to land and water problems. The satisfactory operation of the ponds are dependent upon various site and construction factors. The final design may be less than desirable because of the time needed for study of the influencing factors, the random nature of these factors, and the general nature of some of the design criteria. The preliminary evaluation is probably the most important aspect of stabilization pond design and usage. Once the pond is in operation, the only solution for many of the problems may be expansion or relocation. The objectives of this project were: a) to evaluate the overall influence of stabilization ponds on the surrounding environment, b) to evaluate site conditions (location, soil, etc.) of various ponds in relation to their operation and acceptance, c) to evaluate special construction practices which will assist in overcoming problems caused by site selection, and d) to develop a method for rapid, economical site selection and to suggest construction practices for this pond location.
