Abstract:This report presents the results of a series of laboratory tests to investigate phosphate transport in sediments subjected to one dimensional consolidation type loading. P-32 techniques are employed. The results indicate that measurable transport occurs for phosphate concentrations on the order of 2 mg p/gm dry soil or more and for loads in excess of the preconsolidation load for the samples. In addition, the report discusses models for the exchange of phosphates between sediment or soil in lakes and lake waters. These models are expressed in a form that allows them to be used to predict the environmental impact of construction operations in aquatic environments. Three modes of interaction are discussed: 1 ) exchange due to new soil surfaces being exposed, 2) exchange due to the dispersion of soil particles in the water, and 3) release due to forced drainage of water from sediments. The conditions under which each mechanism might be influential are discussed and mathematical models are developed for quantitative predictions.
