Webgroundwater if a large amount is discharged into regions where groundwater circulates in a very thin zone near the surface. The suitability of an area for the use of conventional septic tank systems was found to be a function of potential leaching field failure, groundwater contamination, and population density. The particular example discusses A leaching model is a hydrological model by which the leaching with irrigation water of dissolved substances, notably salt, in the soil is described depending on the hydrological regime and the soil's properties. The model may describe the process (1) in time and (2) as a function of amount of water applied. Leaching is often done to reclaim saline soil or to conserve a favorable salt content of the soil of i…
