The influence of seasonal changes (pre monsoon, during monsoon and post monsoon) on the Physico-chemical properties of the water in Ara, Bhojpur district (Bihar) was investigated. A total of sixty water samples from different sources (ie, bore wells, hand pumps, tap water) are taken. The experiment analyses its various Physico- Chemical parameters such as Temperature, Turbidity, pH, Electrical conductivity ,TDS,TH,TA,Ca2+,Mg2+,Cl-,No3 - ,So4 2-,Fe,As,F- content in water. Also maximum value of parameters in all seasonal changes results in Ara block of Bhojpur district, Bihar also compared with EOROPEAN, USPH, ICMR standards to investigate the level of water quality for all uses.
