This study examined the impact of Bisphenol A (BPA) on the physicochemical and bacteriological characteristics of water in storage tanks in Salem University Lokoja. Borehole water samples were collected from three (3) locations within the University environment and stored in a jerry can for analysi
s. Total Heterotrophic Bacteria Count (THBC) in water samples ranged from 1.00± 0.30 x10
4 at week 0 to 8.95±1.00 x10
4 cfu/ml at week 3, while the total coliform count (TCC) also ranged from 1.30±0.15 x10
4 to 7.11±0.82 x10
4 cfu/ml. TCC and THBC were found to be higher than the NSDWQ Standard. The identified isolates from the borehole samples were
Escherichia coli
,
Pseudomonas aeruginosa
,
Streptococcus faecalis
,
Bacillus cereus
,
Staphylococcus epidermidis
and Serretia spp. Bisphenol A (BPA) was not detected in week 0, after week 3, components of Bisphenol A detected were methyl chloride, Benzene and Dichlorobenzene and their highest values were 0.054±0.033, 0.021±0.020 and 0.055±0.062 mg/l respectively. The pH, Turbidity, Total suspended solids, BOD and conductivity reduced as storage increased. Magnesium and calcium for sample B were found to have the highest value of 0.31 and 1.73 mg/l respectively. Storage of water for a long period of time should be discouraged as it could trigger increased leaching of BPA into the water which will affect its physicochemical and microbiologically quality.
