This paper presents the results of physico-chemical observations during the period from February 1958 to January 1960, to ascertain between water chemistry and the state of pollution in the River Yamuna. "Excess chloride" was found to be the best parameter for determining the extent of pollution (sewage and natural drainage) in this river. The "oxygen balance" provided a useful measure of the ability of the river to cope with pollution under the prevailing conditions. Stream discharge exert an overriding influence on most of the parameters of pollution. There is an indication of self-purification in the river, but this process is retarded by the entrance of sewage and natural drainage at different places.
