Assessment of Physicochemical and Bacteriological Quality of Different Surface Water Samples of Tangail District, Bangladesh

Abstract

Surface water, a vital element of ecosystem must be hygienic, but unfortunately the pollution of this water is now an alarming problem. The present work deals with the assessment of physicochemical and bacteriological profile of several untreated surface water sources to ensure its suitability for using domestic purposes and drinking along with the impact of bacterial contaminated water on public health and antibiotic resistance pattern of these bacteria. The samples were collected from twenty sampling point (13 ponds, 4 lakes, 2 rivers and one canal) of Tangail District from January 2017 to June 2017. To understand the seasonal variation, water samples were measured in two month; February (dry season) and June (wet season). Most of the water sampling points were polluted by dumping of waste, cattle wash and were not suitable for the drinking or other domestic purposes. Obtained results showed that water of the study area is slightly alkaline, no remarkable variation in the temperature of the water in both seasons and DO of all the sampling station were lower than standard limit during February. The mean concentration (M.C.) of total Coliform were 4 × 10 22 cfu/100ml and 4.5 × 10 18 cfu/100ml at cfu/100ml at June) were isolated from several of the investigated water sources. The total counts of these pathogenic bacteria exceeded the acceptable limit during both season and also showed resistance against a broad range of commercially available antibiotics. People who were using these water frequently suffering from various water borne diseases. These untreated water sources pose a major threat to the public health and therefore need for exigent intervention by government.

Determination of Microbiological Load in Periwinkle (Tympanotonos fuscatus), Water and Sediment of Azubie/Woji Creek, Port Harcourt, Nigeria

“…This result disagreed with the report by Sroczynska et al 14 , who recorded a higher bacterial load in oyster Crassostrea thizophorae tissues than in water. This result was in line with the assertation by Jahan et al 8 15 , which reported that excessive human activities might lead to an increase in organic matter, resulting in a high microbial load in the water.…”

“…Aquatic assets are influenced by their surroundings, therefore water becomes insecure for life both in water and land as a result of the pathogen, which may occasionally restore the natural surroundings and also prevent additional contamination 7 . The causes of bacteria in the river environment remain clearance of human left-over and municipal wastewater over sewage and drainage ditches systems resulting in the distribution of pathogens 8 .…”

Hydrobiological assessment of two lakes of Jahangirnagar University campus, savar, Bangladesh

“…The mean values of water temperature for both lakes were 23 ± 4.13°C and 24 ± 4.24°C, respectively. It was stated that water temperature should be between 20 and 30℃ to support aquatic life (Jahan et al 2017). In the limnological study of lake Ashura, Dinajpur, Bangladesh, the average air and water temperatures were found to be 31.5 ± 0.25ºC and 30.0 ± 0.45ºC, respectively (Alfasane et al 2012).…”

Linking between contamination of environmental water and Salmonella foodborne illness: A Review

“…Among the samples of 144 tap water 3.47% was positive for IpaB gene. The prevalence study shows that ponds, lake, rivers and canal (13, 4, 2 and 1) in different location of Tangail District of Bangladesh found 5 Salmonella positive sample out of 20 water samples (33) . They found most of the water sampling spot were polluted by dumping waste, cattle wash and were not unable to drink or other domestic purposes.…”
