Abstract Quality assessment of water is essential to ensure sustainable safe use of it for drinking, agricultural and industrial purposes. For the same purpose the study was conducted for the samples of water of Nacharam area. The study area is characterized by semi arid climate and due to absence of surface water resources ground water is the main supply in this region. In order to evaluate the suitability of ground water in Nacharam area for using drinking and irrigation purposes. APHA were used to analysis 10 water samples were collected only from hand pumps and analyzed pH, electrical conductivity, total dissolved solids, Na + , K + , Ca 2+ , Mg 2+ , HCO 3 - ,Cl - and SO 4 2- . To understand the water quality indices parameters like, Sodium absorption ratio, salinity diagram, and piper tri linear diagram was calculated based on physic chemical results and observed that the higher concentration of total dissolved solids, total hardness, nitrates, chlorides, calcium, magnesium rendering unsuitable for drinking purposes. The values of electrical conductivity and SAR were plotted in the US salinity laboratory diagram, most dominant classes C4S1, C4S2, C3S1 were found. The quality of groundwater with high salinity and medium sodium, SAR in most water samples has restricted water quality for irrigation purpose. Keywords: Groundwater quality, Piper trilinear diagram, US salinity laboratory diagram. Introduction Water is very vital for nature and can be limiting resource to men and other living beings. Without a well functioning water supply, it is difficult to imagine productive human activity be it agriculture or livestock. Water quality is influenced by natural and artificial effects including local industrial waste pollutants, geology and irrigation practices the hydrogeochemistry of water is important to quality in water supply planning for living areas. The geochemical character of any groundwater determines its quality and utilization. The quality is function of the physical, chemical and biological parameters and it should be subjective, since which depends on a particular intended use. The various on hydrogeochemistry of water quality have been carried out by various members. Laluraj et al.(2005) have been studied ground water chemistry of shallow aquifers in the costal zones of Cochin and concluded the ground water present in the shallow aquifers of some of the stations were poor in quality and beyond the potable limit as per the standard by World Health Organization (2004). Rapid increase of urbanization and industrialization leads to deterioration in hydrogeochemistry of ground water quality. Srinivas et al. (2000) and Jha and Verma (2000) have reported the degradation of the water quality in Hyderabad and Bihar, Respectively, Patnaik et al (2002) have studied water pollution generated from major industries similarly, waste pollutants or effluents. Discharged into streams may enter the aquifer body down stream. This also affects the ground water geochemistry. The studies on trace metals have been carried out (Jangir et al. 1990; Sharma et al.)Sharma et al (2004) Singh and Chandel (2003, 2006) pollution problems in ground water and industrial waste water have been studied. The specific objectives of the present study area 1) the investigations and interpretation of hydrogeochemistry of Nacharam and adjoining areas. 2) Find out the suitability of groundwater for irrigation and drinking purpose and 3) establish significant correlation among ton parameters of ground water samples.

Rangareddy) in the NE of Andhra Pradesh state, is undergoing rapid urbanization and industrialization.
