The aim of the study is to evaluate the seasonal variations of physico-chemical parameters of the New Calabar River at Aluu in order to ascertain its productivity. Physico-chemical parameters of the upper reach of the New Calabar River at Aluu were investigated during dry and rainy seasons for 17 months. The water was acidic most of the period pH was between 5.12 to 7.43 with low total hardness values ranging from 11.5 to 51.2 mg CaCO3/L which indicate that the water is soft. There was an obvious significant seasonal variation in temperature (23.1 to 31.7°C), transparency (9.30 to 19.00 cm) and total hardness with dry season values higher than the wet season values. Hydrogen ion concentration (pH), dissolved oxygen (5.20 to 7.50 mg/L) and dissolved oxygen deficits (0.02 to 2.95 mg/L) however, exhibited insignificant seasonal variations. These results are useful for several stake holders who use the river as a sink for trade wastes, as source of water for fish farming and water treatment plants and as means of transportation of industrial materials.
Key words: New Calabar River, physico-chemical parameters, seasonal variation, , , ,
