An Experimental Study on the Effect of Wastewater Application in Dry Wells and Its Impact on Groundwaterby Reza M. Khanbilvardi, City Coll, New York, NY, USA,
Abstract: A study was conducted in order to gather accurate information on the effectiveness of dry wells for use in wastewater disposal and the effect of such disposal practice on groundwater. To determine this effect, accurate information on the variation in the quality of wastewater during percolation through soil was obtained in a laboratory test. The results of the study indicated that wastewater can be renovated to some degree in limestone soil media. Ca and Mg hardness and ammonia nitrogen concentrations increased with increasing soil depth. While, pH and alkalinity were essentially unchanged during the percolation process at depths beyond two feet of soil.
