Pollution Research
Groundwater has been considered as an important source of water supply due to its relatively low susceptibility to pollution in comparison with surface water, and its large storage capacity. It should be mentioned that water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives (in) it. When humans drink polluted water it often has serious consequences on their health. Water pollution can also make water unsuited for the desired use. In this context, an attempt has been made to assess the ground water quality of Ujjain city. Samples were collected from 17 locations of Ujjain city from various ground water sources for summer season and analysed for physico-chemical parameters .The results of analysis were compared with the Indian standards (BIS, IS 10500:1991) of drinking water quality parameters. The pH values of all samples indicate with in desirable limit. Turbidity, alkalinity, t...
Water quality is considered as a big issue in many cities of developing countries. Bore well water is valuable than surface water but due to different activities done by human being this water is contaminated. And now-a-days this is the grave problem. In those areas of Indore city where the door to door garbage pickup vehicle brought their garbage, the assessment of the bore well water was carried out. At assessing the water quality index (WQI) and physico-chemical parameters for the ground water of Indore the present work is aimed. For a physico-chemical analysis, ground water samples of selected location were collected. For calculating the present water quality status the following quality parameters were considered: pH, electrical conductivity, TDS, total hardness, COD, total alkalinity, turbidity, sulphate, chloride. After calculating water quality status of considered parameters, results are compared with IS: 10500-2012. This ground water sample's physico-chemical characteristics suggest that the evaluation of water quality parameters should be carried out periodically.
Assessment of Water Quality Index of Ground Water in Narsapur Mandal, Telangana
The present work is aimed at assessing the Water Quality Index (WQI) for ground water samples collected from 19 major villages of Narsapur mandal, Telangana state. Telangana state is classified as hard rock area where surface water resources are limited, with the result, groundwater has become a major source of supply to the village population. This has been determined by collecting ground water samples and subjecting the samples to a comprehensive physio-chemical analysis. In order to determine the quality of the water for drinking water purpose, following parameters were considered: Potential of hydrogen (pH), Total dissolved solids (TDS), Alkanity, Total hardness, Chloride, Fluoride, Nitrate, Sulphate and Iron. The results have been compared with the drinking water standard prescribed by Bureau of Indian Standard (BIS). All the physiochemical parameters are within the prescribed limit except Total Hardness for Chippalturthy village and Ibrahimbad village. Regular monitoring of groundwater quality, abolishment of unhealthy waste disposal practices and introduction of modern techniques were highly recommended. The Study also indicates the usefulness of WQI in estimating the drinking water quality of the ground water.

This paper mainly focusing on to assess the water quality index (WQI) of ground water and pond water of sirsakala village of bhilai-3, Chhattisgarh, India. In the present study nine water samples of Bhilai-3, were collected from the different locations of sirsakala village during Oct.2012–Sept. 2013 and fifteen water quality parameters have been considered such as pH, EC, TDS, turbidity, hardness, Fluoride, calcium, magnesium, chloride, DO, BOD, sulphate, alkalinity, nitrate, and COD were studied and compared with the standard values prescribed by ICMR and BIS. The water is characterized by very high contents in excess of the maximum prescribed limit of Indian Council for Medical Research and Bureau of Indian Standard. However, most of the water samples did not have high concentrations of the toxic contaminants. The present investigation revealed that the some of the ground and pond water samples of source sirsakala village of Bhilai-3 are not suitable for domestic, bathing, drinking purpose and they needs some treatment before consumption and it is also needs to be protected from contamination.
Assessment of water quality index for ground water of industrialized area of Surat city, Gujarat, India have been done by calculating Water quality Index value. The physicochemical analysis of 09 ground water samples namely Pandesara housing colony, Pandesara gam, Bhatpor, Bhestan, Udhna Gam., Limbayat, Damka, Sachin GIDC, Sachin gam were done by using APHA standard methods of analysis. The results of the analysis when compared with desirable limits of Indian standards for Drinking Water (IS: 10500.1993), in all the 09 sampling stations, most of the selected water quality parameters were observed above desirable limit. The WQI values of 09 ground water samples located nearer to industrialized area were found in the range of 179.82-1257.2 in winter season, 219.2-1290.11 in summer season, 167.42-1244.6 in post monsoon season. Based on average value of WQI, highest WQI was found in ground water sample of Udhna Gam (1263.97). Udhna Gam is very nearer to the Udhna GIDC (which are having 700 large scale and 6000 small scale industries of textile, chemical, pharmaceutical and metal industries) and the Udhna Khadi is 1.0-1.5 km away from the sampling point into which effluents of industries are discharged. The higher values of WQI was found (for all 09 ground water samples) in summer season may be due to the lowering of water table, while the values of WQI in winter and post monsoon season is comparatively lower due to recharging of bore wells in the rainy season. All 09 ground water samples of industrialized area were having high WQI values, from these results, it is concluded that none of the studied 09 sources can be used for drinking, domestic or for industrial purposes.

Assessment of ground water quality of Hamirpur District, Uttar Pradesh, India
The study was designed to predict the water qualities at different areas of Hamirpur District Uttar Pradesh, India. Physico-chemical parameters were investigated TDS, pH, fluoride, nitrate, chloride, sulphate, hardness and alkalinity. The results were compared with drinking water quality standards prescribed by the Beauro of Indian Standards (BIS). Ground water sampling carried out in January 2014 to April 2014. Most of the water samples were found to have total dissolved solids, alkalinity and hardness values more than their permissible level. The values of heavy metals (Cd, Cu, Fe, Pb, Ni and Co) also determine in collected water samples. The high values of these parameters might have health complications and so they need attention. The above studies are helpful to understand the ground water quality and their subsequent fitness or unfitness of water for drinking domestic purpose at various sites undertaken.
Ground water being the pristine resource plays an important role in fulfilling the needs for domestic, industrial and irrigational purposes. It is of prime importance to civilization, as is the largest resource of drinking water. Pollution of this resource has become an issue of great concern with increased urbanization and industrialization. Contamination of groundwater by industrial effluents, agricultural fertilizers and domestic sewage are recognized as a major threat. Many of the pollutants make their way into the groundwater and change its quality. This work is thus aimed at investigating the seasonal variations (pre-monsoon, monsoon and post-monsoon) in groundwater quality from Sirpur-Kaghaznagar and its suitability for drinking purposes for which ground water samples were collected and analysed on the basis of various qualitative parameters from 24 different stations and evaluated for physico-chemical parameters by implementing standard methods. Water quality index (WQI) was calculated based on 12 parameters. The study revealed that the groundwater quality was altered with respect to parameters, such as pH, EC, TDS, Ca 2+ , Mg 2+ , Na, TH, F, SO 4 2 , and NO 3-. Water quality index calculated for three seasons ranged to fall in good to unsuitable category attributed to the use of agricultural fertilizers by farmers, by paper industry effluents and mineral composition of aquifers in the study area. The suggested measures includes, proper disposal of effluents by paper industry, change in cropping pattern and creating awareness at local level. IJEP 37 (10) : 805-813 (2017)
