Quality assessment of vintage premium table water elele Rivers State of Nigeria for some years

The analysis of the physical, chemical and microbial properties of vintage premium table water in Elele Rivers State of Nigeria were studied for its level of compliance with Standard Organization of Nigeria (SON) specifications for drinking water quality for over some years and seasons. The comprehensive water analysis were done over the years by certified public analytical companies and establishments. Experimental results showed that the physicochemical parameters; odour, colour, taste, pH, conductivity, total dissolved solids, copper, iron, zinc, chlorides, sulphates, nitrates, nitrite, fluoride magnesium, manganese, mercury, barium, cadmium, chromium, aluminium, arsenic, lead, hydrogen sulphide, phenol, mineral oil and chlorine residue were found to comply with specifications for drinking water. The microbial screenings also comply with SON specification. The statistical analysis showed that though the samples were fit for drinking, there were variation in some measured parameters which suggested inconsistency in their concentrations for the studied years.
