The analysis of different parameters such as pH, turbidity, Total hardness, Chloride, Sulphate, Nitrate, TDS, Potassium, Magnesium, and Iron were carried out as per standard methods. The results obtained on WQI from different sampling stations were found to be varied from 27.70. In all the samples are Compare with the standards of WHO, BIS and USPH. The perusal of the results revealed that the water is safe for drinking and domestic purposes in selected sampling regions. The present study also indicates that application of water quality index in estimating the quality of ground water appears to be promising in the field of water quality management. The analysis reveals that some of the groundwater of the area needs treatment before consumption.
The present study aimed to calculate Water Quality Index (WQI) by the analysis of twenty-one physico-chemical parameters on the basis of Weighted Arithmetic Index in order to assess the suitability of ground water for drinking in Kattedan Industrial Area, Ranga Reddy District, Andhra Pradesh, India. Water Quality Index, a technique of rating water quality, is an effective tool to assess spatial and temporal changes in ground water quality. It serves the understanding of water quality issues by integrating complex data and generating a score that describes water quality status. The WQI is used to classify water quality as excellent, good, poor, very poor and unfit for drinking. The parameters were measured for the calculation of WQI at nine groundwater sampling locations in September 2012.The found values were compared with the ICMR/BIS water quality standards. The results observed on WQI for the different sampling locations were found to fall under the class of poor (100-200) class at sample locations S1,S2,S5,S6,S7 to very poor (200-300) class at sample locations of S3,S8 and S9.The analysis reveals that the ground water of the area was not conforming to drinking standards and hence needs some treatment before consumption, and it also needs to be protected from the perils of contamination. It is concluded that WQI can be used as a tool in comparing the water quality of different sources.
Groundwater is a natural resource for drinking water. Assessment of ground water quality status in Mysore city by using water quality index (WQI) method was carried out. From the sampling locations spread throughout city, 53 groundwater samples were collected both in pre-and post-monsoon seasons.

Groundwater quality should be continuously monitored for irrigation and drinking purpose so that risk from geochemical contaminants can be reduced by appropriate treatment method. Therefore, the focus of the present study was to determine the suitability of groundwater collected from South West Delhi, India, for irrigation and drinking purpose on the basis of various water quality indices. In order to assess the groundwater quality, 50 samples were collected from different sites of selected study area and parameters such as pH, EC (electrical conductivity), total dissolved solids (TDS), salinity, total hardness (TH), total alkalinity (HCO 3 −), calcium (Ca þ 2), magnesium (Mg þ 2), sodium (Na þ), potassium (K þ), chloride (Cl −), Fluoride (F −), sulfates (SO 4 −2) and Nitrates (NO 3 −) were determined. Based on the above parameters, sodium adsorption ratio (SAR), soluble sodium percentage (SSP), residual sodium carbonate (RSC), permeability index (PI), magnesium adsorption ratio (MAR), Kelley's ratio (KR) and Na% were calculated. Water quality index (WQI), which is an important and unique rating to represent the overall water quality in a single term that is useful to determine the suitability of water for human consumption, was also estimated. The present dataset demonstrated the application of water quality indices that would be helpful to policymakers for appropriate management, treatment and sustainable societal development at large.

Groundwater is a characteristic asset for drinking water. Like other normal assets, it ought to be surveyed consistently and individuals ought to be made mindful of the nature of drinking water. The present study is gone for evaluating the water quality index (WQI) for the groundwater of Gwalior district. This has been executed by collection of groundwater samples in January and February months and subjecting the examples to a far reaching physico-chemical investigation. For ascertaining the WQI, 8 Parameters have been viewed which are; pH, electrical conductivity, alkalinity, Acidity, total hardness, chloride, total dissolved solids, total suspended solids. The result shows that the water quality index of the current study fall in poor category for these water samples and ranges from 43.33 to 106.58. The high value of water quality index has been observed to be primarily due to higher concentration of Total dissolved solids, hardness and Alkalinity in the underground water of the villages. In general, water in some studied areas is acceptable to a certain limits only and need to be further treated before using for drinking purpose.
