Spectral analysis of total suspended solids mixtures for solids composition determination
Total Suspended Solids (TSS) analysis provides an initial and very basic measure for study and characterization of water quality. The present tedious procedures used for the identification of different solids constituents present in TSS and for the classification or insight into the origins of …

Testing the use of the BASINS PLOAD model to simulate the quality of stormwater runoff from the Kuils River catchment, Cape Town
… affecting the quality of freshwater resources. Total phosphorus and total suspended solids represent two forms of pollutants that are commonly found in non point source discharge...This study evaluated water quality modelling as an alternative monitoring technique. The study was aimed at …

An investigation of the effects of temperature and suspended sediment on the Landsat MSS reflectance of John H. Kerr Reservoir
… period of record. The effects of temperature and total suspended solids on Landsat MSS reflectance were investigated. The effect of increasing temperature was a notable decrease in reflectance especially in Bands 4 and 5. This temperature effect may have been influenced by other water quality …

Water quality and sediment dynamics in a detention pond system
… the design enhanced the removal efficiency of total suspended solids (TSS) and, to a lesser degree, nutrient constituents in the runoff. The design increased TSS flocculation, which ensured particulate removal, and protected settled particles from resuspension by scouring.

Evaluation of Constructed Wetlands for the Waste Management of a Large Scale Swine Production Unit
… following: ammonia nitrogen, nitrate nitrogen, total phosphorus, total suspended solids, dissolved solids, dissolved oxygen, biological oxygen demand, and Fecal Coliform Bacteria. The wetland was divided into nine connected cells that covered approximately 3.8 hectares. Material was loaded from …

Agricultural and forest land runoff in upper South River near Waynesboro, Virginia
Sources and yields of organic matter, suspended solids and nutrients in the Upper South River Basin were investigated during the summer low flow period of 1974. Parameters monitored at sampling stations in the basin included chemical oxygen demand, total suspended solids, turbidity, specific …

Does it pay to be mature? Assessing the performance of a mature bioretention cell seven years post-construction
… months to determine initial flow reduction and total suspended solids, and nutrient removal. By monitoring for the same parameters, changes in cell performance since installation were quantified. ISCO automated stormwater samplers collected inflow and outflow composite samples from the cell, …

Control of agricultural nonpoint source pollution in Kranji Catchment, Singapore
… phosphorus, and bacterial species, as well as total suspended solids. High nutrient and bacterial concentrations were observed at sampling locations in the upstream region of the subcatchment, with total nitrogen as high as 19.8 mg/L, total phosphorus as high as 2.12 mg/L, and a peak total …

Investigation factors that control trace metal toxicity in coastal systems : a temporal and spatial analysis of kinetically inert copper in Boston Harbor
… Cu. Correlations between Cu concentrations and total suspended solids at one sampling location suggested that sediment resuspension may be a source of inert Cu to coastal waters. Consistently significant inert Cu concentrations at a site near a salt marsh implied that the presence of sulfides …

An investigation of the environmental factors that affect water quality and the occurrence of harmful cyanobacteria in stormwater management ponds
… including toxic cyanobacteria. Net release of total phosphorus (TP) and net retention of total nitrogen (TN) by SWMP were observed. Flow conditions had little affect on the overall functioning of the study SWMP. Large pond designs and recent dredging were observed to positively influence the …

Hydrologic impacts due to application of dust suppressants
… decrease in the amount of loading for total suspended solids and phosphate and an increase in the loadings for sulfate and chloride. A reapplication of a dust suppressant further changes hydrologic characteristics and quality of runoff from treated plots.

Evaluation of Nutrients and Suspended Solids Removal by Stormwater Control Measures Using High Flow Media
… over 11 months to assess the removal of Total Suspended Solids (TSS), Nitrogen, and Phosphorus in First Flush (FF) stormwater runoff. Excellent removal of TSS and particulate-bound nutrients was noted, but, in most SCMs, removal of dissolved species was limited. Sorption of dissolved P …

Use of polymers and a surfactant in the treatment of Kraft process wastewater
… system before being removed by flotation. Total suspended solids removal improved with increasing column detention time.

Simulation of local watershed nutrient and sediment delivery to Lake Texoma.
… used to estimate the loading of nutrients and total suspended solids from un-gaged local watersheds associated with Lake Texoma. Discharge to the reservoir from local watersheds was predicted using a modification of the curve number method in HEC Hydrologic Modeling System (HEC-HMS). Event mean …

Effects of the composition of suspended particles in water on the photosynthetically usable radiation and remote-sensing reflectance
The total suspended solids concentration of a water body, usually denoted as TSS, is a useful indicator of water quality. The TSS is often empirically related to the downwelling irradiance (Ed) and above-surface remote-sensing reflectance (Rrs). However, the same TSS can result from different …

An introduction to the study of phosphorus dynamics in Rondevlei
… Soluble Reactive Phosphorus (SRP), calcium (Ca), Total Dissolved Solids (TDS), Total Suspended Solids (TSS) and Particulate Organic Matter (POM) were measured in the laboratory.

Evaluation of stormwater BMP alternatives in the Malden River Watershed
… wetland would cost $3.9 million and provide 50% Total Phosphorus reduction, 57% Total Suspended Solids reduction, and 33% flow reduction. However, limited land availability constrains the development of a wetland within the study site.

Effectiveness of water quality benefits provided by stormwater management facilities/infiltration basin
… in Medford, NJ to verify if the 80% expected Total Suspended Solids (TSS) removal as stated in the New Jersey Stormwater BMP Manual is actually achieved. A sampling pit was installed on the site and infiltrated water samples were collected during three rain events and TSS measurements were …
