Well water was successfully recharged to the Meade formation in Southcentral Kansas through a pit and a well. However, when surface runoff water was recharged, the surface of the pit became sealed over for all practical purposes and the specific capacity of the well was reduced from 44 to 31 gallons per minute per foot of drawdown. Recharging of the aquifer appears feasible provided the water is of high quality. In laboratory filtration studies, the turbidity of a slurry made up from tap water and topsoil was lowered from 30 to less than 10 Jackson Turbidity Units by passing it through filter cloths. The filter cloth served only as a septum upon which a cake formed and the turbidity was reduced by the forming filter cake. Flow rates after 24 hours varied from 0.10 to 0.34 gallons per minute per square foot and are comparable to flow rates through slow sand filters. (Author)
