![]() ![]() The GWQI number is a weighted arithmetic index computed by combining selected water quality parameters to assess water state with relative to its desirable water quality objectives and to communicate information on overall quality status of water to the concerned user community, policy makers and to the environmentalists. The ground water quality index (GWQI) is one of the major evaluative techniques to quantify the level of water pollution with respect to a specific standard. ![]() In current investigation, physico-chemical and biological parameters namely temperature, pH, conductivity, total dissolved solids (TDS), total suspended solids (TSS), total solids (TS), dissolved oxygen (DO), free CO2, turbidity, alkalinity, acidity, total hardness, calcium hardness, magnesium hardness, calcium, magnesium, sodium, potassium, sulphate, phosphate, nitrate, chloride, chemical oxygen demand (COD) and total coli forms of ground water samples of Vadodara City were assessed for a period of four months (December 2016 to March 2017). Local, regional, and global assessments of water quality monitoring are the key component of environmental management of aquatic resources.įurthermore, it is crucial to understand influence of various activities on water resources both in terms of negative and positive impact. The main goal of the present study is to evaluate the groundwater quality in shallow and deep aquifers with respect to time and place in parts of Vadodara district for the purposes of drinking and irrigation. which lead to depletion of ground water resources. The demand of ground water in Vadodara has increased due to its agriculture expansion urbanization, industrialization, etc. Vadodara is a semi-arid region of Gujarat with 4.1 million human population (according to the 2011 census) and mainly relay on ground water resources. Rapid urbanization has affected the availability and quality of groundwater due to it’s over exploitation, open defecation, leach ate generation from the sludge, and improper waste disposal. The aquifers are highly affected by the introduction of physical, chemical and biological pollutants although, groundwater are filtered through the soil. Dynamic nature of groundwater resources are affected by different factors such as urbanization, industrialization and irrigation activities. Groundwater has been extensively used in Vadodara on account of its near universal availability, dependability and low capital cost. Keywords: Ground water quality index Ground water Drinking water Water monitoring VadodaraĪbbreviations: GWQI: Ground Water Quality Index TDS: Total dissolved solids TSS: Total Suspended Solids TS: Total Solids DO: Dissolved Oxygen COD: Chemical Oxygen Demand WQI: Water Quality Index These results evidently indicated the use of water filtration or/and treatment before consumption of ground water of Vadodara city and it is also needs to be protected from contamination. GWQI analyses showed better ground water quality in the monitoring stations located in the underdevelopment area of the city than those stations located in the developed area. Based on GWQI, most the ground water samples have been included in good water to poor water category. The calculated GWQI for these sampling stations ranges from 41 to 193 with a mean values 100. ![]() Ground water quality index (GWQI) was calculated on the basis of BIS standards of drinking water specification. Electrical conductivity, TDS, turbidity and alkalinity were found to be higher as compared to BIS standards of drinking water due to presence of ions such as Na +, K +, Ca 2+, Mg 2+, PO 4 3-, SO 4 2, NO 3 - and Cl. In current investigation ground water quality were monitored and assessed along the urban area of Vadodara including Gorwa, Nizampura, Harni, Gotri, Sayajiganj, Fatehgunj, Ajwa Road, Tandelja, Lal Baug, Makarpura and Tarsali monitoring station. ![]()
