Physico-Chemical Properties of the Water of River Ganga at Ghazipur

Physico-chemical properties of the water of River Ganga were studied at five different sites, viz, Site I^st -Patthar Ghat Site II^nd -Bada Mahadeva Ghat Site III^rd -Dadari Ghat Site IV^th -Collector Ghat Site V^th -Chitnath Ghat during the September 2005 to August 2007 rin river Ganga at Ghazipur U.P.
