Evaluation of Lead and Iron Content in Different Stages of Water Treatment Facilities within Otuoke and Yenagoa Metropolis, Bayelsa State, Nigeria

Abstract

The mechanism of keeping water safe by improving its quality makes it easily accessible for community health. The objective of this work was to evaluate the levels of lead and Iron in the domestic water supply system at Ekeki Housing Estate Yenegoa local government and Otuoke community in Ogbia local government in Bayelsa State, Nigeria.  AAS version 5.0 Model was used to analyze Iron and Lead after acid digestion. Results obtained were compared with WHO standard, and statistically inferences were drawn using ANOVA and Spearman correlation matrix. All water sampled presented values of lead between (0.02-0.64) mg/L expect for point I3 and I4 which conformed to 0.01mg/L, while Iron values ranged from (0.01-5.3) mg/L.  Most of the results obtained exceeded the WHO standard of 0.01 mg/L for lead and 0.03mg/L respectively. The research findings had shown that most treatment processes adopted were not suitable for treatment of the contaminants, hence the need to review treatment processes, distribution and monitoring of the source.
