Eutrophication of lakes due to increased loading of nutrients negatively affects water quality, warranting worldwide efforts to reduce the limiting nutrient in most lakes, phosphorus (P). Government regulations on excess nutrient loads entering the James River Arm (JRA) of Table Rock Lake, Missouri began in 2001 with upgrades at a major sewage treatment plant (STP). The present study aims to quantify the spatial and temporal distribution of sediment P in the James River Basin by (1) quantifying present sediment-P concentrations in the basin, (2) describing the spatial patterns of sediment-P reduction, and (3) investigating the link between upstream sediment and P sources and JRA sediment-P response. Lake sedimentation zones are identified based on physical and chemical sediment characteristics and lake morphometry. Sediment-P concentrations are highest immediately downstream of the STP (620-1,190 ppm) and in the JRA (370-1,580 ppm) and are lower in the James River (170-640 ppm). Sediment-P concentrations in the JRA are strongly correlated to depth and Mn (r2 = 0.92). Sediment-P concentrations have decreased downstream of the STP since 2001, ranging from 14-58% in stream sediments, and 31-36% in the JRA. Lake sediment-P reductions are greatest in deeper areas of the JRA. Concentrations of A1 have decreased by 9-70% in the James River and Wilson's Creek, and have increased in the JRA by 9-34%, potentially reflecting the influence of STP treatment procedures or variable sediment sources on sediment geochemistry. Nonpoint P may have increased since 2001, warranting future attention.
The research work contained in this report concerns the transport of total phosphorus and orthophosphorus to Lake Erie. The various calculational techniques for analyzing data obtained from Lake Erie tributaries are presented. These calculations were developed to determine the source of the phosphorus and to quantify the input to the lake. The source and quantity of phosphorus devised for Lake Erie. The first section of this report presents the basic concepts, mass balances (that applied to the water and that applied to the phosphorus), and force relationships. The second section of this report concerns the quantification of total phosphorus input to Lake Erie river basins and shortline sources. A computational method called the Flow Interval Method was devised to permit the calculaion of total phosphorus influx without measuring the total phosphorus concentration for the entire year. Another important aspect of reducing total phosphorus influx from river basins is the understanding of the transport processes in rivers. The third section of this report concerns the transport of total phosphorus during storm events. The fourth section of this report presents the derivation of the necessary equations used to calculate the distance of the travel density function form measurements of the water flow rate and the total phosphorus concentrations at a point in the stream.
This comprehensive book provides an up-to-date and international approach that addresses the Motivations, Technologies and Assessment of the Elimination and Recovery of Phosphorus from Wastewater. This book is part of the Integrated Environmental Technology Series.
