A água engarrafada é uma das formas comercializadas de água potável. A procura e o consumo de água engarrafada estão a aumentar rapidamente devido à sua fácil disponibilidade, conveniência e por ser geralmente considerada segura para consumo. O consumo de água contaminada com bactérias coliformes e heterotróficas pode causar doenças transmitidas pela água, como diarreia, febre tifóide, cólera, etc. A qualidade bacteriológica da água engarrafada foi analisada neste estudo utilizando a técnica de filtração por membrana e placa de difusão. Entre 24 amostras de água engarrafada coletadas aleatoriamente, nenhuma amostra estava livre de bactérias e apenas 12,5% das amostras eram bacteriologicamente seguras para consumo. Este estudo também encontrou E. coli em 54,2% do total das amostras de água engarrafada, o que indica contaminação fecal recente na água. Este estudo destacou a qualidade da água potável engarrafada, que pode causar sérios problemas de saúde pública. O resultado da análise realizada pode ser útil para os consumidores, pesquisadores e autoridades competentes.
