ABSTRACT

 

The levels of nitrate, phosphate, sulphate, chloride, Dissolved Oxygen, (DO) Biochemical Oxygen Demand (BOD) and some physical parameters of the water resources in a typical rural community in Nigeria were assessed in this report. The study was aimed at finding out the impact of agricultural activities on the various water bodies-streams, hand dug shallow wells and lakes/ponds in a setting with 97% of populace engaged in agriculture. Standard methods were used in the determinations. Results of the study showed that 61.5% of the water bodies studied had nitrate overload. Sulphates were within the recommended limit while the level of phosphates was also higher than the set limit. Chloride, TDS and pH were all within the recommended level. Organic matter load in the waters were significant as shown by decreased values of DO. Although epidemiology records of effects of excess nitrate consumption in the studied area were nonexistent due to some factors, it is not unlikely that health risks associated with excess nitrates in food and water are wide spread.
