Abstract: | Multivariate water quality parameters and statistical analysis were used to evaluate the factors controlling coastal drinking water quality and associated health risks among fisherfolks. Multidrug-resistant strains noticed in 400 isolates show 62% Salmonella; 53% Shigella sp.; 48% E. coli; and 36% Vibrio sp. in groundwater sample. In component analysis seawater intrusion, redox reaction, anthropogenic pollution, and weather factors were responsible for more than 93.3% in postmonsoon and 89.4% in summer season, respectively, for Cumulative %. In epidemiology study, 66% and 76% of municipally supplied drinking water were used in Pondicherry and Rameshwaram, respectively, compared to the amount of groundwater (34% and 20%) used in the study area. Similarly, Pondicherry and Rameshwaram areas recorded open defecation instances of 94% and 82%, respectively where less than 5% of the population used hygienic sanitation as part of the Clean India Mission in rural areas. |
