ANALYSES OF THE PHYSICOCHEMICAL AND MICROBIOLOGICAL QUALITIES OF SELECTED SACHET WATER BRANDS IN NNEWI, ANAMBRA STATE, NIGERIA
Abstract
This study analyzed the physicochemical and microbiological qualities of five sachet water brands mostly
consumed in Nnewi. The researchers used respective meters for the physical parameters, an atomic absorption
spectrophotometer machine for the heavy metal determinations and streak-plate method for the determination of
microbiological parameters. The five sachet water brands that were used for this study were elicited from
respondents in Nnewi using a well-structured questionnaire. The study estimated the pH, electrical conductivity,
total solids, heavy metal contents, total count bacteria and microbial isolates of the microbiological parameters of
selected sachet water brands. Averaged results of the physicochemical parameters showed that pH estimated at
5.928, electrical conductivity-0.2636μS/m, turbidity-0.0092NTU, total dissolved solids-44.64mg/L, and total
suspended solids-30.54mg/L. In addition, averaged results of the heavy metal parameters showed that lead was
estimated at 0.012mg/L, cadmium-0.0576mg/L, copper-0.0252mg/L, iron-2.496mg/L, zinc-0.85mg/L,
chromium-0.051mg/L and cobolt-0.8602mg/L. Results of the microbiological parameters showed that for total
count, Christo was estimated at 24 x 104MPN/100ml, Carter- 22 x 103MPN/100ml, Uru- 22 x 104MPN/100ml,
Aqua-Rapha- 21 x 103MPN/100ml and Chem-Paully- 78 x 103MPN/100ml. The study recommends that sachet
water regulatory agency should ensure that sachet water brands are produced under hygienic environment in
order to safeguard the public health of residents.
