EFFECTS OF KADUNA METROPOLITAN LANDUSE ON KADUNA RIVER WATER QUALITY

ABSTRACT

 The aim of this study is to determine the effects of Kaduna metropolitan land use on Kaduna River water quality in Kaduna state; Nigeria. To achieve our stated aim; the following objectives are put forward: to identify the sources of pollution in Kaduna river; to assess the quality level of Kaduna river in the Metropolis in relation to land use zones, to determine the spatial and seasonal variation of water quality of the river; to assess the level of awareness of residents of the Metropolis on effects of their activities on the quality of the river, and to examine the consequences of pollution in water quality of the river on human health. Data were got from primary and secondary sources. For primary data, water samples were collected from five sample points and analyzed for the spatial and seasonal quality variation for 21 parameters (temperature, pH, conductivity, colour, turbidity, TSS, TDS, DO, Ammonia, Nitrate, Nitrite, BOD, COD, Oil and grease, phosphate, copper, calcium, Magnesium, iron, Zn and faecal coliform), in situ through field determination of water quality and laboratory based analysis at Kaduna State Environmental Protection Authority laboratory. The study was carried out in two seasons-dry and rainy seasons to determine the seasonal variations. Water samples were purposively and carefully selected and collected to ensure that the samples were collected upstream, within and downstream of the land use types respectively. Data were also got through questionnaire administration. With a population of 767,306 for Kaduna Metropolis, about 435 questionnaires were printed and distributed purposively and randomly to the target population. 407 copies were filled and returned successfully given us 93.56% coverage. The secondary data were publications written by authors who included books, articles in journals, and Government documents. Hospital records were obtained for a trend of 10 years from Kaduna State Ministry of Health and DR Gwamna Awan General Hospital, Kakuri in Kaduna Metropolis. The study adopted descriptive statistics, T-test, ANOVA, correlation analysis and paired T-test to analyze and achieved our results. Charts and line graphs were used. Results shows that (i) the major sources of pollution in Kaduna river are agricultural run-off, industrial effluents and discharges, run-off from urban centre, surface run off and natural source; (ii) human activity of the metropolis have effects on the quality of Kaduna River (iii) Kaduna River shows seasonal quality variation (iv) the level of awareness of the residents is high; and (v) cases of water borne/water related diseases is high in the study area. The findings shows that the variety and level of pollution in Kaduna River is related to the size of population, and land use activities on the various parts of the Metropolis from where it receives run-off and pollutants. Following the findings of this research, it is recommended that prevention of pollution, treatment of polluted water, safe use of wastewater, restoration and protection of ecosystem, among others are desirable actions that will gurantee not only sustainable good quality but also use of Kaduna River water by man.
