Statistical Modelling of Groundwater for Environmental Sustainbilty

Abstract

In the worldwide calculations groundwater of urban areas has been depleting very rapidly by leaving its huge scarcity for the upcoming future generation due to uncontrolled and unpredictable census year by year along with migrations from rural to urban areas, at the other face the available groundwater is becoming polluted due to the unscientific handling like over lifting of water years together from one particular point which caused intrusion of pollutants in to the underground aquifers along with releasing of chemicals and other pollutant substances on the open ground as well as in to the nearby water bodies are the prime reasons for groundwater contamination. Modeling of groundwater with respect to its quality along with the quantity is an immediate need to be taken why because groundwater plays vital role and very important component to meet the total requirement of water lifting from the underground aquifers for both domestic and agricultural needs. By lifting water from the same point there is a possibility for deteriorating of water content in that aquifer and it may leads to permanent destruction of water quality in that respective aquifer, to overcome these consequences the modeling technique where withdraw of water will be regulated along with injection of water into the aquifer can be adopted. In the present study we have identified ten sampling localities from Guntur municipal corporation, Andhra Pradesh, India by considering severe problems associated with groundwater in both quality and quantity point of view, in all the locations five sub locations were identified for water sampling. Samples were collected for three times from the bore wells and hand pumps, average of three times analysis was considered as final values. Analysis was done by using standard analytical methods. The results were compared with IS 10500 -2012 drinking water quality standards to get the scenario of water quality.
