Seasonal Variations of Some Physico-Chemical Properties of River Ethiope Water in Abraka, Nigeria

The influence of seasonal changes on the properties of water from Ethiope River at Abraka was investigated. Composite samples from six different sampling points were collected and assessed for both dry and wet seasons. The sampling points represent the villages within Abraka clan along the river. The seasonal variations are as follows. Wet season has mean pH as 6.82, temperature 27.73°C conductivity 81.7μs/cm, TDS 0.26mg/l TSS 16.21, DO 16.80mg/l, BOD 4.50mg/l. The results for the dry season is as follows; mean pH 6.82, temperature 29.150C, conductivity 87.2μs/cm, TDS 0.34mg/l, TSS 15.21mg/l, DO 17.45mg/l, BOD 4.38mg/l. The result of heavy metal content showed that they were within the permissible levels. This water can therefore be said to be portable in all seasons.
