摘要: Correlation curves were developed relating nephelometric turbidity units (NTU) with total suspended solids (TSS) for diked upland dredged material placement site effluents of three US Army Corps Engineers (COE) maintenance dredging projects in the Chesapeake Bay, Maryland. The procedure was an effort to ensure compliance Maryland's 400 milligrams per liter (mg/l) TSS standard COE projects. Samples sediments be collected and analyzed, correlating readings determined by gravimetric techniques. correlation provided inspectors measure effluent a meter extract concentration from curve. analyzed after initiation indicated that overestimate actual concentrations discharges. procedure, endorsed State Maryland, immediate on-site analysis eliminating previously encountered delays obtaining discharges potential contract management problems.
