Abstract
A study of water quality parameters of ground water of North, Central and South regions of Kalol Taluka in Gandhinagar district of Gujarat state, India have been carried out during May2006. The observed values of various physico-chemical parameters of water samples were compared with standard recommended by World Health Organization (WHO). The analysis of variance (ANOVA) and t-test have been applied for the comparative study of water quality parameters among various regions of Kalol Taluka. The variance was found significant at 1% level of significance in case of Electrical Conductivity, Magnesium Hardness, Chloride Content and at 5% level of significance in case of pH, Total Dissolved Solids, Total Hardness, Chemical Oxygen Demand among the water samples of above three regions of Kalol Taluka. Established order of water quality of various regions of Kalol Taluka is North Kalol>Central Kalol>South Kalol.
Highlights
Water is the basic necessity of life, for human beings, and for plants and animals
There are some ways in which bodies of water get polluted; discharge of untreated domestic sewage into water ways; discharge of industrial effluents; discharge of agriculture wastes into water way; use of pesticides, herbicides, fungicides and weedicides which seep into ground water; discharge of fertilizer residues as run-off from farm lands into water ways
Analysis of variance (ANOVA) and t-test were determined for comparison among the water quality parameters of ground water of North, Central and South regions of Kalol Taluka as per the methods described by Rangaswami-5
Summary
Water is the basic necessity of life, for human beings, and for plants and animals. Scientists estimate that water covers nearly three fourth of earth’s surface in the form of oceans, rivers, lakes, snow, glaciers and ground water. Though this seems an inordinately huge amount; in actual fact, less than one percent is fresh and usable found in lakes, ponds, rivers and ground water. Studies of physico-chemical characteristics of ground water or drinking water of various villages of various talukas in Gujrat State have been carried out by various workers[1,2,3]. We carried out a study of physico-chemical parameters of borewell water of North, Central and South regions of Kalol Taluka and data were analyzed statistically using coefficient of variance (%CV), analysis of variance (ANOVA) and t-test
