Assessment of drinking water contamination in food stalls of Jashore Municipality, Bangladesh

Abstract

This study aimed to determine the quality of drinking water supplied in different types of food stalls in Jashore Municipality, Bangladesh. A total of 35 water samples were collected from different tea stalls, street side fast food stalls, normal restaurants and well-furnished restaurants. The water quality was evaluated by determining the distinct physical, chemical and biological parameters. The results revealed that the water used in the food stalls and restaurants for drinking purpose was in desired quality in terms of turbidity, electrical conductivity, pH, total dissolved solids, nitrate (NO3−), sulfate (SO42−), phosphate (PO43−), chloride (Cl−), sodium (Na) and potassium (K) concentrations. The values were within the permissible limit proposed by the Bangladesh Bureau of Statistics and the World Health Organization. Concentrations of calcium (Ca) and magnesium (Mg) found in several samples were higher than the World Health Organization standard. Iron (Fe) concentrations were higher than the permissible limit of the World Health Organization. Only 46% exceeded the permissible limit of Bangladesh Bureau Statistics. The threatening result was that the samples were contaminated by fecal coliform, indicating that the people of Jashore Municipality may have a greater chance of being affected by pathogenic bacteria. The drinking water provided in the street side fast food stalls was biologically contaminated. The findings demonstrate that the drinking water used in food stalls and restaurants of Jashore Municipality did not meet up the potable drinking water quality standards and therefore was detrimental to public health.

Groundwater Quality of Some Parts of Coastal Bhola District, Bangladesh: Exceptional Evidence

“…The Odor, Color, and Taste: The DTW water samples did not have any odor. The odor was very simple, as with the other samples normally found in GW in Bangladesh [36]. Similar to odor, the color of the samples was also very simple, as found in other samples of GW reported recently [36].…”

“…The odor was very simple, as with the other samples normally found in GW in Bangladesh [36]. Similar to odor, the color of the samples was also very simple, as found in other samples of GW reported recently [36]. The taste of the collected samples was as usual.…”

“…In most cases, the taste of the water samples was good (tasteless). This is because soil can act as a natural filter for GW [73] and can be drunk without any disinclination [35,36,65].…”

“…Recently, numerous types of research have been performed to verify the water quality in different coastal parts of Bangladesh, e.g., Satkhira [8,24,28], Khulna [29,30], Patuakhali [31], Gopalganj [32,33], Jashore [7,[34][35][36][37][38][39][40], and central south parts of Bangladesh [31,41]. Not only has those, but also the water quality been determined in other parts of The changing climate may have impinged on the cropping pattern of Bangladesh from the primeval period [6].…”

Assessment of Drinking Water Quality : A Case Study in Barishal District, Bangladesh.

“…The drinking water supply in Bangladesh has almost entirely been based on groundwater sources [3].About 97% water is exists in oceans that is not suitable for drinking and only 3% is fresh water wherein 2.97% is comprised by glaciers and ice caps and remaining little portion of 0.3% is available as a surface and ground water for human use (Miller, 1997) [4].The current population of Bangladesh is 165,939,921 as of Wednesday, April 7, 2020, based on Worldometer of the latest United Nations data with an area of 130,170 Km2 (50,259 sq. miles [5].About 98% of people having access to water from technologically advanced water sources; the quality of water in Bangladesh is still poor (Islam et al 2015; Shaibur et al 2019e, f) and about 41% of all improved water sources in Bangladesh are contaminated with E. coli despite of remarkable progress in improving access to water supply and sanitation (Shaibur et al 2019b) [5]. The present study is carried out to characterize the groundwater and its suitability analysis for consumption by the city dwellers which may act also as guideline to the citizens and policy makers [6].The study was conducted to achieve the following objectives:…”
