Bacterial Contamination Levels and Brand Perception of Sachet Water: A Case Study in Some Nigerian Urban Neighborhoods

Sachet water (SW) is a major source of drinking in most Nigerian homes, thus making it possible conveyance medium for health risks due to contamination if persist rather than replenishment the body. This study collected SW from three busy neighborhoods South-West Nigeria and investigated presence indicator bacteria (Escherichia coli (E. coli), Total Coliform (TC), Heterophilic Bacteria (THB), Staphylococcus (Staph)) some physio-chemical parameters (total dissolved solids (TDS), pH, electrical conductivity (EC), salinity). Multi-variable exploratory statistical methods were applied results determine correlations between bacterial levels perceived brand reputation. Bacteriological tests with raw samples appeared too numerous count (TNC) required serial dilutions. After seven-fold dilutions, obtained revealed that brands good reputations had no TC E. was statistically significant groupings other (χ2 = 12.28; p < 0.05 χ2 37.96; 0.05). Additionally, poor mean values (19.7×108 cfu/mL; 14×108 cfu/mL 1.15×108 cfu/mL) (18.2×108 38.7×108 cfu/mL,32.4×108 exceeding threshold value zero set by World Health Organization (WHO). Only one sample reputation tested positive not 5.2191; 0.074). Principal Component Analysis (PCA)/Factor (FA) fecal source. Therefore, this suggests periodic cleaning distribution lines, location-specific treatment, quality control (QC) measures should be enforced reduce security risk consumption region.
