Quality Assessment of Surface and Drinking Water of Nakla Paurosova, Sherpur, Bangladesh

Abstract

Water is one of the most vital elements of ecosystem and human being, but unfortunately nowadays, the pollution of surface and drinking water is an alarming problem. The present work deals with the assessment of physicochemical and bacteriological profile of several pond, jar and tube-well water samples to ensure its suitability for using and drinking. Total 30 samples were randomly selected and collected from Nakla Paurosova of Sherpur district by following the standard procedure. Bacteriological analysis was carried out by following the standard bacteriological methods. Most of the surface water sampling points were polluted by dumping of waste, cattle wash and were not suitable for drinking or other domestic purposes. Among three heavy metals, only Iron was detected in six tube-well water samples, one was also positive to arsenic, rest of the water bodies were negative to all of these metals.

Effects of fish stocking density on growth and survival of Silver carp (Hypophthalmichthys molitrix) fry in Jashore, Bangladesh

“…The mean values of total alkalinity were found 155.78±2.518, 154.89±3.091 and 154.64±2.677 mg/l in T-1, T-2, and T-3, respectively. These results are relatively like those of (Sahoo et al 2020, Sarker et al 2019, Wurts 2002. From the above discussion we might conclude that all the experimental ponds for present experiment were most suitable for silver carp fish fry culture.…”

Hydrogeochemical Characteristics, Quality Assessment and Health Impact Analysis of Groundwater for Drinking in the University of Chittagong, Bangladesh

“…Nearly neutral water was previously reported for the supply water of Chittagong city, which is comparable to our findings [99]. Water which is acidic or weakly acidic in nature indirectly indicates the presence of very low amounts of inorganic sediments or domestic and agricultural wastes [100]. Nonetheless, acidic water contributes to corrosion of metals coupled with disinfection efficiency, which is responsible for indirect effects on humans [101].…”

Health Risks Associated With Sources of Water: An Exploratory Study From Turag-Tongi Riparian Areas, Bangladesh

“…Moreover, the work of More (2017) demonstrates that in Bangladesh, very high E. coli risk levels (p>100 CFU/100 mL) were found in 46.3 percent of piped water into dwellings and 3.6 percent of tube wells. The presence of microorganisms in the tubewell water of Bangladesh is also confirmed by the work of Hoque et al (2006), Rahman et al (2014), Kabir et al (2016), Sarker et al (2019), etc. Thus, disease incidence among the studied communities might result from microbial components and other harmful contaminants in their relied water sources.…”

“…Due to the practice of discharging untreated domestic and industrial waste, rivers in urban areas have also been linked to water quality issues. This has increased the level of toxic metals (Rashid et al, 2012;Zakir et al, 2013;Hasan et al, 2014;Islam et al, 2015), fecal coliform, and other harmful bacteria (Zuthi et al, 2009;Sarker et al, 2019), which has a variety of adverse health effects (Schwarzenbach et al, 2010;WHO, 2012;Alidadi et al, 2019;Lin et al, 2022;Sing et al, 2022). Usage of contaminated water from both safe and unsafe sources causes various waterborne diseases like diarrhea, cholera, jaundice, typhoid, hepatitis, etc.…”
