1 IJEP 34 (12) : (2014) (Received on November 22, 2013) Interpretation of Groundwater Quality by Shaded Contour Method in and Around Pendlimarri Area of Kadapa District G.Sudarsana Raju and M.Ravikumar Yogi Vemana University, Department of Geology, Kadapa The present study was undertaken to assess the water quality in relation to agriculture and domestic use in and around Pendlimarri area. The study area is mostly composed of quartzites, shales and limestones. The groundwater samples from the wells of the study area were collected and the chemical analysis for various parameters were carried out. The quality analysis was made through the estimation of calcium, magnesium, chloride, fluoride, total dissolved solid, hydrogen ion concentration (ph) and specific conductance. Based on the analysis, various shaded contour maps have been drawn. Assessment of water samples from various methods proved that majority of the water samples were good either for domestic or for agricultural purposes. -

2 IJEP 34 (12) : (2014) (Received on March 21, 2014) An Overview of Microbiological Aspects of Ground Water Quality Assessment S.K. Maiti, Adarsh Kumar and Rashda Khanam Indian School of Mines, Centre of Mining Environment, Department of Environmental Science and Engineering (ESE), Dhanbad Ground water as a source of drinking water is considered as safer source than surface water. During recharge of ground water, soil acts as natural filter. The extent of ground water contamination depend on rainfall pattern, depth of water table, distance from the source of contamination and soil properties. Recently WHO reported that microbial contamination is causing death of more than 3.4 million people per year throughout the world and developing countries are more severely affected. The great majority of waterborne infections are the result of faecal contamination, either from humans or animals, leakage of sewage and industrial effluent entering water supplies used for drinking purposes. In this paper, methods of analysis of bacteriological contamination, process of movement of pathogen in ground water, coliform standards, sampling process, testing methods and examination of pathogens are discussed. KEYWORD Total and fecal coliform, movement of pathogen, microbiological testing, standards.

3 IJEP 34 (12) : (2014) (Received on March 19, 2014) Impact of Industrial Effluent on Water Quality of River Hindon at Bagpat District S. Shekhar, Vishnu Kant and H. Shekhar V.K.S. University, Department of Chemistry, Ara The present paper describes the pollution in Hindon river water of Bagpat district, U.P., due to industrial activity going on in the region. To assess the level of quality and pollution in the river, water sample of 3 sampling station, namely SI (Barnava), SII (Pura Mahadev) and SIII (Mohammadpur Ahmad) have been investigated with the help of physico-chemical and bactrological parameters, such as ph, conductivity, turbidity, TDS, TSS, TS, BOD, COD, total hardness, Ca, Mg, phosphate, nitrate, alkalinity and total coliform density using WHO water quality standards. The water samples were collected and analysed during pre-monsoon (March to May), monsoon (June to September) and post-monsoon period (October to February) in It has been found that these water samples have very high conductivity, turbidity, TSS and also highly bactrologically contaminated.

Salinity is common problem in the Sundarbans. The Piyali river is a tributary of the Matla river which discharges into the Bay of Bengal. The basin of Piyali river, an estuarine river with regular tidal influx, with special emphasis on Kultali block of the Sundarbans has been chosen for utilizing the water of the Piyali river during dry months. Sea water contains chlorides with other salts that can be detrimental to agricultural crops and drinking water quality as they exceed the drinking water standards. In this paper, an attempt has been made to investigate whether there is any extent of the salt water intrusion to the Piyali river from Matla river during pre- monsoon season which indirectly verifies proper functioning of sluice gate alongwith determination of physico-chemical parameters to identify the water is fit for irrigation and drinking purpose. Water samples from different locations of the Piyali river have been analyzed for their contents regarding salinity, chloride, total dissolved solid, total solid, turbidity, electrical conductivity and ph in order to improve management options. KEYWORD Sundarbans, Piyali river, Irrigation water, Drinking water, Water quality, Salinity.

Gupta Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Department of Energy and Environment, Faculty of Science and Environment, Chitrakoot , Satna The concentration of Fe, Cd, Cr, Pb, As and Hg in water and sediment of river Mandakini have been studied in Chitrakoot stretch of 30 km from Sati Anusuiya (M.P.) to Surya Kund (U.P.). Grab samples of water and sediment (March, 2013) were collected and analyzed for heavy metals, namely Cd, Cr, Hg, Fe, Pb and As using AAS. The concentration of heavy metals found in the river water was in the range of , , , , for Fe,Cd, Cr, Pb and Hg, respectively. In the sediments the concentration range was , , , , µg/gm for Fe, Cd, Cr, Pb and Hg, respectively. Some physico-chemical parameters, namely temperature, ph, TDS, Ca hardness, Mg hardness, total hardness. Cl-, NO3- were also estimated. Investigations showed that all the 6 sampling sites were suffering from slight to moderate water pollution. River Mandakini, Water, Sediment, Heavy metals, Physico-chemical parameter.
