Physico-chemical parameters of Seepage stream at Kushaha area

Physico-chemical parameters of the Seepage stream of Kushaha area were studied for two years from July, 2002-June, 2004, once in every month at regular intervals. The monthly data were pooled in seasonal value. The maximum air temperature was recorded in rainy season during first year study period (July, 2002 to June, 2003) but in the second year study period (July, 2003 to June 2004) it was maximum in summer season. Water temperature was maximum in summer and lowest in winter season. Transparency, PH, dissolved oxygen, total alkalinity, total hardness, chloride were recorded maximum in winter season. Free carbondioxide, and biological oxygen demand was maximum in summer season. The minimum transparency, total alkalinity, total hardness and chloride were recorded in rainy season. Dissolved oxygen, and PH, were minimum in summer season. The minimum carbondioxide and BOD were recorded in winter season. Air temperature, water temperature, free carbondioxide, biological oxygen demand showed positive and significant correlation with each other. Similarly, transparency, PH, total alkalinity, total hardness, chloride, showed positive and significant correlation with each other. Dissolved oxygen showed positive and significant correlation with pH, total alkalinity, total hardness and chloride.
