Impact of sewage water on physico-chemical characteristics of soil of Bikaner City

The quality of waste-water at Vallabh Garden and Madhosingh Bari in Bikaner is quite poor for irrigation and is deteriorating the growth of crops and altering the physical and chemical properties of soil. To study the impact of the polluted water on the soil, it was necessary to examine the physico-chemical characteristics of soil. In order to examine the quality 11 soil samples were collected to determine the concentration of some parameters as pH, conductivity, total dissolved solids, total hardness, alkalinity, chloride, potassium, sodium, zinc and iron. The study of the parameters revealed that. the variation of these parameters is significant. Variation in values of parameters with distance in soil samples was also studied. If irrigation with this polluted water continues there is very possibility of human beings developing intestinal diseases and the land become barren. The quality of soil of Vallabh Garden is much poorer than Madhosingh Bari. Values of parameters are very high in Vallabh Garden soil and heavy metals, i.e., iron and zinc are also present in toxic range in this soil Therefore it should be used after treatment.
