EVALUATION OF THE INFLUENCE OF AGROCHEMICALS AND LEACHATES ON GROUNDWATER QUALITY AND PUBLIC HEALTH IN NIGER STATE

Abstract

This study aimed to assess the impact of agrochemicals and leachates on groundwater quality and public health in Niger State and its environs. Water samples were collected from wells in four different areas, namely Minna, Suleja, Bida, and Lapai, between February and November 2019. Thirteen parameters were analyzed to determine the chemical constituents of the water and the level of pollution in the project area. The results indicated that the groundwater quality was within the Nigerian Standard and WHO standard, except for electrical conductivity in one of the areas. However, the study identified that good agricultural practice, proper timing, and application of exact quantities of agrochemicals, and prevention of spillages during applications must be followed to maintain groundwater quality and public health. The study found that contamination of agrochemicals and leachates in groundwater was insignificant, and there was no strong connection between their presence and public health-related issues. The study recommended the continued practice of good agricultural practices and the prevention of spillages during applications. This study provides insight into the effects of agrochemicals and leachates presence in groundwater on public health and the importance of appropriate farming practices. The results highlight the significance of monitoring and maintaining groundwater quality and how human activities can alter the composition of groundwater.
