WILL THE Drainfield Work? (cover story)

The article reports on research and developments on hydrogeologic investigation on wastewater particularly on drainfields in the U.S. According to the report, hydrogeologic investigation typically involves installation of monitoring wells for field measurement of the depth on water table and subsequent finding of groundwater flow direction and hydraulic gradient. It is inferred that the Hydrus numerical model, software that provides a Microsoft Windows-based modeling environment, could analyze water flow and solute transport in variably saturated porous media. Thus, uses the Richard Equation. An overview on modeling in a wastewater distribution area is also offered.
