The study assessed water chemistry of Nworie inland aquatic ecosystem in South eastern, Nigeria from January, 2020 to December 2022. Water samples were taken from the upper, middle, and lower river at 200m interval. Data collected were subjected to multivariate analyses. Results of physicochemical tracers indicated mean CaCO3, Ca2+& Chemical Oxygen Demand (COD) to be 172.8mg/l, 103.1mg/l, 16.50mg/l respectively above the World Health Organisation (WHO) critical limits, while turbidity (NTU), dissolved oxygen (DO) mgl-1, chloride (Cl- ) mg/l, Magnesium (Mg) mg/l, Sodium (Na) mg/l, sulphate (SO4...
