Abstract - Water is an essential natural resource for sustaining life and environment, but over the few decades the water quality is deteriorating due to it’s over exploitation. Groundwater is the major source of drinking water in rural as well as in urban areas and over 94% of the drinking water demand is met by groundwater. Due to human and industrial activities the water bodies are contaminated and this is the serious problem nowadays. Thus, the analysis of the water quality is very important to preserve the natural ecosystem. The study was carried out to assess the water quality index (WQI) for the ground water of PEENYA. For this purpose, water samples were collected from different bore wells of PEENYA INDUSTRIAL AREA, BENGALURU. The ground water samples of all the selected bore wells were collected for a physiochemical and biological analysis. For calculating the present water quality status by statistical evaluation, following 22 parameters have been considered viz. pH, colour, turbidity, Total Dissolved Solids (TDS), conductivity, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), total hardness, calcium, chloride, zinc, sulphate, magnesium, alkalinity, fluoride, boron, copper, iron, chromium, odour, nitrate, manganese, residual free chlorine, E-coli. pH value in the study area found from 6.65 to 7.35. Total alkalinity between 246 mg/L to 435 mg/L. Total hardness ranged from 520 mg/L to 1100 mg/L and calcium varied from 130 mg/L to 265 mg/L. Magnesium varied from 46.8 mg/L to 88 mg/L and chloride from 217 mg/L to 468 mg/L. Values of nitrate concentration varied from 11 mg/L to 22 mg/L and fluoride from 0.79 mg/L to 0.92 mg/L while value of TDS ranges from 1070 mg/L to 2200 mg/L. The obtained results are compared with IS 10500:2012. The study of physicochemical and biological characteristics of water samples suggests that the evaluation of water quality parameters as well as water quality management practices should be carried out to protect the water resources. Key words: Groundwater, Water quality, Physicochemical characteristics, Biological characteristics, etc., 1. INTRODUCTION Water has a profound influence on human health. At a very basic level, a minimum amount of water is required for consumption on a daily basis for survival and therefore access to some form of water is essential for life. However, water has much broader influences on health and wellbeing and issues such as the quantity and quality of the water supplied are important in determining the health of

individuals and whole communities. The first priority must be to provide access for the whole population to some form of improved water supply. However, access may be restricted by low coverage, poor continuity, insufficient quantity, poor quality and excessive cost relative to the ability and willingness to pay. Thus, in terms of drinkingwater, all these issues must be addressed if public health is to improve. Water quality aspects, whilst important, are not the sole determinant of health impacts. It is most important that the water which people drink and use for other domestic purposes is clean water. This means that the water must be free of germs and chemicals and be clear (not cloudy). Water that is safe for drinking is called potable water. Disease causing germs and chemicals can find their way into water supplies. When this happens, the water becomes polluted or contaminated and when people drink it become very sick. Water that is not safe to drink is said to be non-potable. Throughout history there have been many occasions where hundreds and thousands of people have died because disease causing germs have been spread through a community by a polluted water supply. One of the reasons this happens less frequently now is that people in many countries make sure drinking water supplies are potable. Water supplies are routinely checked for germs and chemicals which can pollute water. If the water, is not safe to drink it is treated. All the action taken to make sure that the drinking water is potable is called water treatment. 1.1 GROUNDWATER Groundwater is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from and eventually flows to the surface naturally; natural discharge often occurs at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Groundwater mainly comes from three sources. They are, first: ‘Meteoric Water’, which is the main source of
