| Abstract | Study Objective: The objective of this applied research was to explore the interaction between effluent sediment concentration and turbidity for sediment controls that are currently being implemented at construction sites. Turbidity can be continuously monitored through an effluent pipe, a flume or in the receiving stream. Monitoring throughout a storm event enables making a more informed decision about the potential impact of effluent on the receiving waters. The impact of Total Suspended Solids (TSS) on various aquatic invertebrates and fish has been extensively documented for certain species. Additionally, the relationship between stream TSS and other environmental factors such as light penetration, growth of aquatic plants, temperature, etc. has been developed for some streams and lakes. If a reliable relationship can be developed between turbidity (TUR) and either suspended sediment concentration (SSC), measured in terms of the mass of sediment in the entire sample, or TSS, then turbidity can be potentially used as a surrogate enabling monitoring that can be readily accomplished at a construction site discharge point. Regulatory Setting: Many government entities are now considering a maximum sediment concentration or turbidity value. These are often applied at the effluent point or sometimes as an in-stream increase, depending upon the type of stream receiving the sediment-laden discharge. Similarly, methodologies are currently being explored to determine the Total Maximum Daily Load (ASAE, 2002) for sediments. When setting regulations it is advisable to not only consider a maximum value based on a large design storm, e.g. 10-year, 24-hour, but to also consider a broader perspective encompassing (1) the occurrence of smaller, more frequent storms during the construction period, (2) the ability to efficiently control the sediment effluent concentration from these many smaller events, (3) the overall impact to the fluvial system and (4) the effect of land |
