| Abstract/Contents: | "The number of on-site wastewater systems in the United States continues to increase as the population increases, with subsequent increased potential for soil-water pollution. Properly functioning on-site wastewater systems are necessary to renovate wastewater before it reaches groundwater or surface water. One method to accomplish this is to use a highly treated effluent, such as recirculating media filter effluent and a subsurface drip irrigation system, where effluent dispersal and dosing frequency can be controlled. A series of soil columns were used to simulate a subsurface drip irrigation system dosed with recirculating media filter effluent at varying application rates (518, 1,036, and 2,071 cm^D3d) and dosing frequencies (6, 12, and 24 doses/d). The two-dimensional code in HYDRUS-3D was used to simulate solute transport (Cl-, NO3-, and PO4-3) in this system. Results show that most of the Cl- was lost from the system in seepage (91% to 98%), whereas seepage (65%) and denitrification (31%) were the primary mechanisms for reducing NO3- concentrations in the soil. Most of the PO4-3 remained in the soil (between 94% and 98%), with seepage loss accounting for a relatively small percentage of the PO4-3 added (from > 0 .01% to 4% at the 518 and 2,071 cm^D3d application rates, respectively). Agreement between the measured and simulated Cl-, NO3-, and PO4-3 concentrations indicated that HYDRUS adequately simulated transport of these solutes through the soil under a range of environmental and effluent application conditions. The simulated PO4-3 concentrations in the soil leachate tended to be slightly higher than measured concentrations and may indicate underestimation of P immobilization based on P sorption isotherms." |
