WATER QUALITY ASSESSMENT OF OSSE RIVER, EDO STATE, NIGERIA, USING SOME PHYSICO-CHEMICAL PARAMETERS

Abstract

This paper reports a sixteen month investigation of the pattern of variation of the physico-chemical parameters of Osse River from January 2003 to April 2004.Water samples for physical and chemical analysis were collected into a 250ml container and analyzed at the chemistry division in Nigeria Institute for Oil Palm Research (NIFOR). The methods described by America Public Health Association (APHA, 1998) were used for physical and chemical analysis. Seasonal fluctuations were recorded among the limnological variables. The driving forces for these fluctuations were the rainy and dry seasons.Apart from pH which was not significantly different (P>0.05), all other parameters studied where significantly different among the stations investigated (P<0.05).
