Abstracts
Bacteriological analyses were carried out on Ananthanar channel water of Kanyakumari district, Tamil Nadu, India. The Ananthanar channel was selected in this study because this channel runs about nearly 28 km and supplies water for many villages for drinking and bathing purposes. Fecal and total coliform counts were performed using the standard membrane filtration technique and multiple tube technique. The results obtained were compared with reports of All India Institute of Medical Sciences Standards for Drinking and Recreational Water. Faecal coliform counts varied from 12 to 180 MPN/100 ml while Escherichia coli counts ranged from 6 to 161 MPN/100 ml for all the sampled sites. Among the total coliform Pseudomonas aeruginosa, Shewanella putrefaciens, Klebsiella pneumoniae, Citrobacter freundii and Proteus mirabilis are reported. The Faecal coliform and the E. coli counts exceeding acceptable limits are indicative of pollution from domestic wastes from several informal settlements located along the riverbank. Water uses in the area were determined and were found to be mainly domestic and recreational. The gross pollution of the river exposes the local people who depend on it for their primary water source to serious health risk.

Análises bacteriológicas foram realizadas nas águas do canal de Ananthanar, distrito de Kanyakumari, Tamil Nadu, na Índia. O canal Ananthanar foi selecionado para este estudo porque ele corre por cerca de 28 km e fornece água a muitas aldeias para consumo humano e para fins balneares. Contagens de coliformes totais e fecais foram realizadas utilizando a técnica da membrana de filtração padrão e técnica de tubos múltiplos. Os resultados obtidos foram comparados com os relatórios de All India Institute of Medical Sciences Standards for Drinking and Recreational Water. A quantidade de Coliformes fecais variou de 12-180 MPN/100 ml enquanto a contagem de Escherichia coli variou 6-161 MPN/100 ml para todos os locais amostrados. Entre todos coliformes Pseudomonas aeruginosa, Shewanella putrefaciens, Klebsiella pneumoniae, Citrobacter freundii e Proteus mirabilis estavam presentes. Coliformes fecais e a contagem de E. coli que excedem os limites aceitáveis são indicativos de poluição oriunda de resíduos domésticos de vários assentamentos informais localizados ao longo da margem do rio. Os usos da água predominantes na área foram principalmente domésticos e de lazer. A poluição do rio expõe as populações locais que dependem dele como sua fonte primária de água a um grave risco de saúde.
