PHYSICO-CHEMICAL ATTRIBUTES OF KANYE DAM RESERVOIR FOR ALGAL GROWTH, IN KANO NORTH-WESTERN NIGERIA

Abstract

Some Physico - chemical attributes of Kanye Dam water reserviour such as; Temperature, pH,
Dissolved Oxygen, Biological Oxygen Demand; Nitrate, Phosphate and Electrical Conductivity
were studied from five (5) sampling sites (A,B,C,D and E) monthly for a period of Six Months
using standard methods of American Public Health Association (APHA). The result revealed the
value of temperature ranged between 24.00 to 28.00ºC with the mean values 25.83ºC pH ranged
between 6.9 to 8.6 with the mean value (7.7).DO ranged between 2.30 to 7.70Mg/L, with the
mean (4.70Mg/L).BOD ranged between 1.20 to 3.70Mg/L with the mean (2.10Mg/L). Nitrate
ranged between 0.40 to 7.60Mg/L with the mean (2.62Mg/L). Phosphate ranged between (0.50 to
3.50Mg/L with the mean (1.00Mg/l), while EC ranged between 510 to 728μs/cm with the mean
(612μs/cm).The analysis of variance showed that there was no significant difference between the
physicochemical parameters within the sampling sites. However there was significant difference
between them within the months of sampling. This suggests that the reserviour water indicates
significant pollution level and therefore can support the growth of some algae.
