Water supply and sanitation status in educational institutions at Tongi of Gazipur district, Bangladesh

Abstract

Water consumption is one of the most important aspects of our daily lives. In this research, 43 samples were collected from 43 educational institutions in the district of Tongi, Gazipur. The collection of samples has been divided into two distinct sections. One is dry season and the other is wet season. Then, all 43 samples from both seasons were analyzed for twelve physiochemical parameters and two bacteriological ones. The parameters consist of pH, DO, EC, TDS, TSS, TS, salinity, turbidity, Fe, Mn, color, As, E. coli, and feces contamination. We have conducted three analyses to comprehend the conditions. First is statistical analysis, then IWQI, and finally Pearson co relation analysis. The current sanitation conditions at the institute were then evaluated. The primary objective of the statistical analysis is to determine what proportion of test results exceed the WHO and ECR (1997) standard parameters. Importantly, one hundred percent of the samples exceeded the E. coli parameters. And approximately four percent of the data exceeded fecal contamination thresholds. Several other parameters have also exceeded the standard parameters, but these two are the most dangerous to human health. On the other hand, according to the IWQI results, nearly 35 percent of water is unfit for consumption during both seasons. In addition, the pearson co-relation analysis enabled us to comprehend the co-relationships between the water parameters for both seasons. The dry season has greater co-relationships than the wet season. And finally, we comprehend the current sanitation conditions of the institutions. Our sanitations have been divided into four categories. Following a study of sanitation ,we've realized that a large number of industries with a large population are contaminating both surface and ground water. Consistent consumption is harmful to human health and the environment. Therefore, we have endeavored to assess the current state of potable water in Tongi, Gazipur region institutions. Proper management and investigation of groundwater quality aids in supplying institutions in Gazipur with potable water of high quality.
