“…The RO system is a more technical and economically feasible drinking water source compared to the other technologies of the study area. The system can also play a great role in a disaster risk reduction (DRR) based program solution of drinking water shortages by building water security related resilience in coastal household level in Bangladesh [46]. Although the potential of desalination plants such as RO require very high cost and energy, it is still in the pilot scale level in some parts of coastal Bangladesh.…”

Impacts of Salinity Intrusion in Community Health: A Review of Experiences on Drinking Water Sodium from Coastal Areas of Bangladesh

Increasing salt intake has substantial negative impacts on human health and well-being. This article focused on the construction of Driver-Pressure-State-Impact-Response (DPSIR) framework for drinking water sodium (DWS) followed by a review on the published studies regarding salinity intrusion, DWS, and their effects on health perspectives in Bangladesh. Saline water is an important factor for hypertension or high blood pressure in the coastal areas. DWS can also lead women, especially pregnant women, to an increased risk of (pre)eclampsia, hypertension, as well as infant mortality. Several interventions, such as rainwater harvesting, pond sand filter (PSF) system, managed aquifer recharge (MAR), and pilot scale solar-powered desalination plants, such as reverse osmosis (RO), were reviewed on the context of their effectiveness in controlling drinking water sodium. Although rainwater consumption has the positive impact of low or no sodium intake, it still possesses negative impacts from not having vital minerals. A steady increment in sodium concentration through the span of the dry season was observed in MAR. It is, subsequently, important to increase awareness on DWS intake by providing and adopting correct technological interventions and training communities on the maintenance of the adaptive measures.

“…Reverse osmosis‐based desalination plants are gaining popularity in coastal Bangladesh, with both the government and NGOs promoting this technology since the early 2010s (Shamsuzzoha et al., 2018). These plants have a production capacity of about 20–60 m 3 per day and mainly purify brackish shallow groundwater by passing it through a semi‐permeable membrane.…”

The 2030 Agenda for Sustainable Development, as articulated in Target 6.1, aims to achieve universal and equitable access to safe and affordable drinking water, using the proportion of population using safely managed drinking water services as the associated indicator (UN, 2015). Despite the progress in increasing "access" to technologically improved sources as part of the Millennium Development Goals (MDG), as of 2017, over 2 billion people lack safely managed drinking water and 785 million do not even have "basic" services (WHO/UNICEF, 2019). Progress to improve water security is most challenging in contexts where financial and institutional resources are limited and where water resources are threatened by chronic (e.g., groundwater contamination) and acute (e.g., floods and cyclones) threats. Bangladesh typifies these chronic and idiosyncratic water security risks, particularly in the coastal region, where around 20 million people live precarious lives with uncertain futures (M. A. Hoque et al., 2016;Shammi et al., 2017).The financial resources that are available for investment of water supplies are inevitably scarce, so governments and development organizations face difficult prioritization problems. Should they adopt a utilitarian approach to maximize for the greater good for the greatest number of people or a Rawlsian social justice approach which prioritizes the "most in need" (Sen, 1974)? The question is complicated by the interaction between public works to provide water supplies and private actors who are willing and able to pay to satisfy their own water needs. In this case, actions by the state may actually crowd out private investments. These competing policy choices are not irreconcilable but present a sequencing and prioritization problem compounded by identification and measurement issues. Without information on the welfare or infrastructure distribution, information asymmetries can lead to perverse outcomes in the spatial distribution of infrastructure, as has been documented in arsenic affected areas in Bangladesh (van Geen et al., 2016).

“…Therefore, interventions like rainwater harvesting, pond sand filter (PSF) system, managed aquifer recharge (MAR), pilotscale solar-powered desalination plants (e.g., reverse osmosis (RO)), were considered in perspective of their efficiency in controlling DWS. Consumption of rainwater, on the one hand, can possess negative impacts from not having vital minerals, and on the other hand, it has progressive impacts of low or no sodium intake (Shamsuzzoha et al 2018;Shammi et al 2016).…”

Salinity is described as the mass in grams of the dissolved inorganic matter in 1 kg of water (Stumm and Morgan 1996). It is hence asserted as S‰in parts per thousand. Seawater has a notably uniform salinity between 33‰ and 37‰. Salinity is also usually measured using the electrical conductivity of water, or more correctly, its specific conductance. The units generally used are either Siemens.cm À1 or mhos.cm À1 (Harris 2009). Infectious disease (or communicable disease) is defined as a sickness caused by a specific infectious agent or its toxic product that appears from the transmission of that agent or its products from an infected person, animal, or reservoir to a susceptive host, either directly or indirectly through an intermediate plant or animal host, vector or inert environment (Last 1988). At the same time, infection is the word that characterizes the entry and development of an infectious agent in a human or animal body, whether or not it develops into a disease (Barreto et al. 2006).
