Water is vital for the world population's domestic, agricultural and industrial purposes and therefore the management of world  water resources becomes incontestable. Reservoirs with urbanised catchment are faced with pollutants of various kinds due to the anthropogenic activities of the people living close to their catchments. An assessment of two reservoirs i.e, Usuma in Abuja and Ureje in Ado-Ekiti, Ekiti State which supply drinking water and with urbanised catchments was conducted with a view to identifying possible sources and the presence of emerging pollutants.  Water samples were collected upstream, downstream and midstream of the dams and analysed.  Results showed that water from the dams had low contamination levels by some persistent organic pollutants (POPs) comprising 0.04 – 0.53 organochlorine pesticides and 0.01 – 0.23 polychlorinated biphenyls (PCBs).  The concentrations of the targeted endocrine disrupting compounds (EDs), was also found to be in the range of 0.01 – 0.02 ng/mL nonylphenol (NP), 0.01 – 0.05 ng/mL octylphenol (OP), and 1.01 – 1.14 ng/mL bisphenol-A (BP A).  The concentrations of all compounds were highest at the upstream of the dams, but were the same at the midstream and downstream of the dams except for the downstream of both dams where BPA were higher.  These might be attributed to the water entering the dams as these compounds are synthetic and do not occur naturally.  The endocrine disrupting compounds and the persistent organic pollutants determined in the water samples collected contained varying concentrations of these compounds.  Thus water of all dams in the country should be surveyed, constantly monitored; and treated as appropriate to make water samples from the dams suitable for desired uses such as irrigation, human consumption, industrial use, aquaculture, and hydropower.
