In the last few decades, the over population and industrial revolution have changed the global groundwater scenario. The majority of groundwater quality problems present today are caused by contamination and over exploitation, or by combination of both. Rapid urbanization and industrialization in India has resulted in steep increase of generation of wastes. Due to lack of infrastructure and resources the waste is not properly collected, treated and disposed; leading to accumulation and infiltration causing groundwater contamination. The problem is more severe in and around large cities including various clusters of industries. In many of these areas, groundwater is the only source of drinking water, thus a large population is exposed to risk of consuming contaminated water. The present study deals with the calculation of groundwater quality index using weighted arithmetic water quality index method (WAWQI) of selected areas of Lucknow city and proposing a model with the help of fuzzy logic toolbox of MATLAB. For this, groundwater samples are collected from different areas of Lucknow city like Aliganj, Gomti Nagar and Amausi and tested for various physico-chemical parameters like pH, total dissolved solid (TDS), total alkalinity (TA), total hardness (TH), chloride (Cl), sulphate (SO4), iron (Fe), nitrate (NO3) and fluoride (F). The WQI is calculated and matched with WQI status along with the statistical analysis of physico-chemical parameters. Secondly, a fuzzy logic model is prepared through which we can determine the water quality of any area considering the above mentioned parameters and classify it into excellent, good, poor, very poor and unfit for drinking (UFD) categories.
