bacteria transport and deposition in calcareous soils under unsaturated flow conditions
abstract microbial contaminants transport to groundwater is a serious environmental problem that can result in large outbreaks of waterborne diseases. some of bacteria can travel from vadose zone and cause contamination of groundwater resources. thus, an accurate prediction of transport and fate of pathogenic microorganisms in unsaturated soil is needed to protect groundwater resources. the mai...
متن کاملSurvival and Movement of Fecal Indicator Bacteria in Soil under Conditions of Saturated Flow I
Antibiotic-resistant fecal bacteria were used to monitor the degree of movement and subsequent ground water contamination by septictank effluent discharged into a drainfield under saturated conditions. Two pits of different depths were constructed to simulate drainfield beds, and ground water samples were removed uring 32-day sampling intervals from sampling wells installed at set distances fro...
متن کاملRemobilization of Americium in calcareous soil columns under experimental rhizospheric conditions
The biogeochemical behaviour of americium in subsurface soils plays a dominant role on its potential migration, but is currently poorly known. This research investigates the relevant processes controlling americium biogeochemical speciation in the rhizosphere of an agricultural soil. Lixiviation tests were performed on columns packed with a calcareous soil contaminated with Am, under steady-sta...
متن کاملEffect of nonuniform boundary conditions on steady flow in saturated homogenous cylindrical soil columns
9 10 11 12 13 14 15 16 17 18 Laboratory column experiments involving steady flow in homogeneous soil are often analyzed assuming that the flow is spatially uniform in any plane transverse to the longitudinal axis aligned with the column centerline. Axisymmetric steady flow in such a column was analyzed to determine the impact of radially nonuniform boundary conditions at the column entrance and...
متن کاملمدلسازی انتقال و نگهداشت آلاینده‌های میکروبی در خاک‌های آهکی تحت جریان اشباع آب در خاک
Microbial transport in soil is critical in different ways, especially in groundwater contamination and bioremediation of groundwater or soil. The main objectives of this research were quantitative study of bacterial transport and deposition under saturated conditions in calcareous soils. A series of column leaching experiments were conducted. Breakthrough curves (BTCs) of Pseudomonas fluorescen...
