摘要：Fresh water is one of the most important resources without which life would not exist on planet Earth. The exponential growth of human population has caused deterioration of global resources with conditions most severe in under developed and developing countries. Physical and chemical contaminants entering in ponds, lakes and other freshwater reservoir have caused devastating effects on floral and faunal diversity of the system. In addition to this, the biological contaminants in general and pathogens in particular are also of prime importance for qualitative analysis of the water quality. Presence of pathogens may cause severe health issues such as infection, diarrhoea, vomiting etc. The issue is very serious specifically in the case of developing countries due to lack of sanitation and prevalence of unhygienic conditions. The current study was aimed to assess biological contamination with special emphasis on coliform E. coli and MPN (per 100 ml). The water samples were drawn from 6 ponds of Vadodara city, Gujarat, India. Out of the 6 ponds studied, 4 showed MPN (per 100 ml) to be 1100 and above showing heavy microbial contamination. Moreover, all of the ponds under investigation showed presence of E. coli which is indicative of faecal contamination. The results of the rapid study provides basis for further expansion of the study with more emphasis on public health risk.
