  • Data Requirements for Soil, Sediment, and Sludge

    Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

  • Modeling of Sedimentation in Stormwater Detention Basins

    ABSTRACTTo minimize the non-point source pollution from roadway surface, the Texas Department of Transportation (TxDOT) initiated a research project for design of a small footprint non-proprietary detention basin, which consists of pipes and box culvert sections with specialized inlet and outlet system. A conceptual model was developed to estimate particle removal efficiency of the rectangular ...

  • Impact of rainwater harvesting systems on nutrient and sediment concentrations in roof runoff

    Rainwater harvesting (RWH) systems have the unique ability to contribute to stormwater management goals via mitigation of runoff volumes and peak flow rates. Additionally, collecting and storing runoff via RWH systems can potentially provide water quality benefits due to physical and chemical processes that occur within the storage tank. This study quantified the water quality improvement ...

  • In Situ Biological Treatment for Soil, Sediment, and Sludge

    The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...

  • Common Treatment Technologies for Fuels in Soil, Sediment, and Sludge

    Common treatment technologies for fuels in soil, sediment, and sludge include biodegradation, incineration, SVE, and low temperature thermal desorption. Incineration is typically used when chlorinated SVOCs are also present with fuel, and not specified for fuel-only contaminated soil, sediment, or sludge. All types of biodegradation, both in situ or ex situ, can be used to remediate soils: ...

  • Ex Situ Biological Treatment for Soil, Sediment, and Sludge

    The main advantage of ex situ treatment is that it generally requires shorter time periods than in situ treatment, and there is more certainty about the uniformity of treatment because of the ability to homogenize, screen, and continuously mix the soil. However, ex situ treatment requires excavation of soils, leading to increased costs and engineering for equipment, possible permitting, and ...

  • Some arguments in favour of a Myriophyllum aquaticum growth inhibition test in a water‐sediment system as an additional test in risk assessment of herbicides

    The present study compares practicability, reproducibility, power and sensitivity of a Myriophyllum aquaticum growth inhibition test in water‐sediment system with the recently accepted Myriophyllum spicatum test in an equivalent testing system and the standard Lemna sp. test. Special consideration was given to M. aquaticum control plant growth and variability of relative growth rate (RGR) and ...

  • Dredging contaminated sediments at an active impact range: an ordnance avoidance success

    At Eagle River Flats, the challenge was to remediate the white phosphorous but leave the UXO (unexploded ordnance) behind. The solution was a dredge system that can withstand a big bang. Eagle River Flats, an estuarine salt marsh located at Fort Richardson in Alaska, has been used by the armed forces for over 50 years as an artillery impact area. During the 1980's, thousands of dead and dying ...

  • Modelling of suspended sediment in a weir reach using EFDC model

    Construction of hydraulic structures often leads to alteration of river dynamics and water quality. Suspended solids entering the upstream of the weir cause adverse effects to the hydroecological system and, therefore, it is necessary to build a modelling system to predict the changes in the river characteristics for proper water quality management. In this study, the discharges and total ...
