AbstractThe suitability of groundwater quality for drinking purpose was assessed in the rural areas of Dwarakatirumala Mandal. Twenty four groundwater samples were collected and various Physico-chemical parameters like pH, turbidity, electrical conductivity (EC), total dissolved solids (TDS), total hardness(TH), Total alkalinity(TA),content of calcium (Ca2+),magnesium (Mg2+), sodium ( Na ), potassium ( K ), Iron (Fe), chloride(Cl-), fluoride (F- ) ,sulphate (SO4
2-), Nitrite(NO2) DO were determined. The spatial distribution of hydro-chemical parameters were also studied.
KeywordsGround Water, Spatial Distribution, Contour Maps, Dwarakatirumala Mandal
I. Introduction Water is one of the most important resource available on earth surface .It is the basic requirement for human activities, industrial desires, agriculture., etc. Most of the earth surface is covered with water ,but only a very little percentage of it is available as surface and ground water for human use.97% of water on the Earth is salt water. Only 3% percent is potable water in the world. yet the supply of clean, fresh water is steadily decreasing in the world. Water demand exceeds the supply in many parts of the world due to increasing population. Ground water is the major source for drinking purpose all over the world because it has inherent advantages over the surface water. Now a days ground water is being contaminated mainly due to anthropogenic activities.The main objective of the present study is to assess the quality
of the ground water in Dwarakatirumala mandal by determining various physico-chemical parameters using standard analytical methods. 24 drinking water samples were collected from different locations of Dwarakatirumala mandal during September month.
II. About DwarakatirumalaThe West Godavari district is one of the 13 districts of Andhrapradesh. It occupies an area of approximately 7700 square kilometers. It has 46 Mandals out of which 24 are in the Upland Region. Geomorphologically the district can be divided into two major regions viz., alluvial deltaic region and upland areas. The deltaic region mostly constitutes black cotton soils and the upland areas are dominated by the red soils. Dwarakatirumala Mandal consists of 24 panchayats and it lies between 16.82538 to 17.03228 Latitude and 81.21615to 81.36818 Longitude respectively.“Dwaraka Tirumala” is an ancient holy place and a popular pilgrim center in Andhra Pradesh of South India. Dwaraka Tirumala is nearer to ‘Eluru’.
III. Materials and MethodsSampling and geochemical analysis is to assess the drinking quality in different villages of Dwarakatirumala Mandal .A systematic sampling was done in Sept 2015. Twenty four drinking water samples were collected in pre washed polyethylene bottles which were cleaned with acid water and hot water followed by rinsing twice with distilled water. The water samples were analyzed by using procedures of standard methods. The samples were collected at bore wells in the previously rinsed polythene bottles.
