Exploration of heavy metals concentration and variation in some selected borehole water from Daura local government, Katsina State, Nigeria

Abstract

Heavy metals such as cadmium lead, and arsenic can contaminate water sources and pose serious health risks when consumed. Considering their potential health implications, this research aim to investigate the presence and explore the variation in heavy metals concentration of some Borehole’s water across Daura local government area of katsina state, and compare the result with the internationally accepted standard concentration value. In this regard, a total of twenty borehole water samples was collected from the site in questioned based on the sediment of the area and the coordinates of the various location used in collecting the samples were recorded. Microwave plasma Atomic Emission spectrometer (MP-AES) was used to obtain the concentration of the five examined heavy metals (Cd, As, Co, Pb and Cr), the mean concentration in part per million (ppm) was obtained using statistical analysis. The results obtained, shows that Daura local government Borehole’s water have an average heavy metal (Cd, As, Co, Pb and Cr) concentration of 0.001, 0.079, 00.298, 0.329 and 0.055 ppm respectively. The differences were seen by comparing the mean concentration of the heavy metals in the study area with world health organization (W.H.O) and NAFDAC threshold limit standard, it was observed that the samples were contaminated with heavy metals which has high risk implication. There is need for urgent intervention and remediation measures by the authority concerned. It was recommended that Water treatment processes should be considered to reduce heavy metal levels at Daura area and Dumpsite should be built in the area so that people should not be dumping refuse and west product anywhere in order to maintain environment stable and free from pollutant.
