“…Heavy metals are released into the environment through a natural process and anthropogenic activities. The sources of drinking water, e.g., surface water (Shaibur et al 2021a, b) and groundwater are likely to be contaminated or polluted by various factors (Shaibur et al 2019f;Shaibur et al 2021b) including heavy metals (Shaibur et al 2012;Shaibur 2019;Shaibur et al 2019a, d;Shaibur and Howlader 2020). Several heavy metals can cause lifethreatening diseases like cancer, e.g., inorganic arsenic and non-cancer, e.g., Hg risks in humans (USEPA 2014).…”

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.

“…The average per-day household consumption of water is around 700 litres for homestead with arable land and 550 litres for homestead with arable land, with ground water accounting for the largest share of this. One of the crucial issues in this region is salinity intrusion, which occasionally restricts the utilization of both deep and shallow tube wells (Shaibur, 2021). Due to minimize the effects of salinization, hand-pump tube wells that draw from the ground water are an important source of domestic water in this village.…”

A Spatial Model Towards Renewable Energy and Water Safe Village

The increasing consumption of non-renewable energy and consequent global warming calls for use of renewable energy at scale. Bangladesh is moving toward ensuring renewable energy for all households by 2025 and has already been ranked 2nd in the world in providing off-grid solar home systems. Yet, national energy generation is largely dependent on fossil fuels and covers about one-third of the rural households. Driven by thriving economic development, villages of Bangladesh are experiencing rapid socio-economic-spatial transformation. However, most of the rural population lives with short of energy and safe water which is the main obstacle in sustainable transformation of rural settlements. To compensate for this shortage, they rely on traditional renewal energy sources such as biomass and solar energy to meet their daily needs. Regarding this energy-water scenario, this research aims to explore the potential of planning renewable energy integrated homestead from a physical-spatial design perspective taking a typical village as the case. With a multidisciplinary-exploratory approach the research is designed with a two-fold methodological framework: 1) investigation of existing energy status (consumption, needs and affordability) and water security (usage, sources and quality); 2) mapping spatial patterns of available energy and water services; and 3) exploration of existing homestead morphology to examine the scope of integrating renewable energy and rainwater harvesting systems in an efficient and cost-effective manner. Based on the triangulation of findings from these investigations, the research develops a Renewable Energy and Safe Water Integrated Spatial Model towards sustainable transformation of rural settlements.

“…Nearly 147 upazilas of these 20 districts are considered coastal upazilas, of which 48 upazilas are coupled to the coast and 99 upazilas are on the inner side of the beach [10]. Climate changes constantly [4,5], which may be responsible for the increasing salinity in the coastal districts of Bangladesh [11][12][13]. A report shows that about 6.69% of the area of the Bagerhat Sadar, Fakirhat, and Rampal upazilas is high in saline, about 85.43% has moderate saline, and around 7.88% of the area is low in saline [14].…”

“…In Bangladesh, around 97% of the residents depend on GW sources for drinking [20]. Around 20 million people in Bangladesh live along the coastal expanse, which is affected by anecdotal degrees of salinity in the drinking water [11,12,21]. In Bangladesh, there is an amplified flood frequency, shifting rainfall patterns, more frequent droughts, and infiltration of salinity.…”

“…Around 20 million people are affected by salinity in the coastal parts of Bangladesh, and they are facing a dearth of pure drinking water [22,23]. The intrusion of saltwater comes from the flow of saline water from side-to-side freshwater aquifers, which may result in the pollution of sources of drinking water [12]. However, there are different results also.…”

The composition of groundwater governs the drinking and irrigation water suitability. A large part of the coastal region of Bangladesh is affected and is responsible for changing the composition of the groundwater. This research attempted to observe the groundwater quality of the Bhola Sadar and Char Fasson upazilas in coastal Bangladesh. Twenty-eight (28) water samples, 27 at depths of 260–430 m (850–1400 ft) and 1 from a crop field, were collected and analyzed. The quality of water samples was determined through the evaluation of odor, color, turbidity, electrical conductivity, pH, total dissolved solids, nitrate (NO3−), ammonium (NH4+), sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn) and arsenic (As) ions. An Atomic Absorption Spectrophotometer was used for heavy metal analysis. The outcomes were compared with the drinking water quality of Bangladesh and the World Health Organization. The results showed that the average values of nearly all of the parameters were underneath or within the standard level, representing that the groundwater was appropriate for drinking purposes. The water quality parameters were also compared with the irrigation water quality of Bangladesh and the Food and Agriculture Organization. It was found that the collected samples were also suitable for irrigation. To do this, the soluble sodium percentage, sodium adsorption ratio, magnesium adsorption ratio, Kelley’s ratio, and total hardness were calculated. The novelty of this research is that, despite being in a coastal district, the deep aquifer water of Bhola was appropriate for drinking and irrigation purposes.
