In addition to arsenic, the groundwater in Bangladesh is often found to be contaminated with manganese whose permissible limit set by WHO being 400 ppb in drinking water. Since most arsenic removal technologies (ARTs) are designed to remove As and not to remove Mn, during field testing and verification of performance of ARTs under the Bangladesh Environmental Technology Verification-Support to Arsenic Mitigation (BETV-SAM) project of BCSIR, it has been found that only the Sono technology using Fe0 as arsenic removal medium which can also remove Mn to produce Mn safe drinking water but others such as Alcan, Read-F household, Sidko, Nelima, Shawdesh cannot. During field testing of these technologies under the BETV-SAM project, it has been attempted to treat Mn by a traditional chlorine oxidation method to produce Mn safe drinking water. Concentrations of dissolved As (T), As (III), Fe, Mn and pH in the considered well water for manganese treatment were in ranges of 125 - 1247 ppb, 116 - 1127 ppb, 1.40 - 15.5 ppm, 505 - 2245 ppb and 7.0 to 7.5, respectively. The required chlorine dose and time for treatment of manganese in 20 L water have been found to be 6.2 - 12.4 ppm and 1 - 2 h, respectively.

Contamination of shallow tube well drinking water by naturally occurring arsenic is a severe societal and human health challenge in Bangladesh. Multiple technological interventions seeking to ameliorate the problem face hurdles in securing social acceptance, i.e. the willingness of users to receive and use a technology. While most papers focus on expert understanding of social acceptability, this paper analyzes how users themselves understand the factors shaping the social acceptability of safe drinking water options in rural Bangladesh. We then deploy such understanding to comparatively assess which factors users see as most important in securing social acceptance for three safe drinking water options in rural Bangladesh: the arsenic removal household (Sono) filter; the deep tube well; and an improved dug well. We draw on focus groups and semi-structured interviews with technology users in six villages across three districts to analyze how users assess the social acceptability of specific arsenic-safe technologies. Our findings highlight that factors such as availability, affordability and compatibility with existing water use practices, as understood by users, are key to securing users' acceptance of a specific arsenic-safe option. In concluding, we point to a future research agenda to analyze user-oriented social acceptability of arsenic-safe technologies in developing country contexts.

The inclusion of packaged drinking water (PDW) as a potentially improved source of safe drinking water under Goal 6.1 of the Sustainable Development Goals (SDG) reflects its growing significance in cities where piped water has never been universal or safe for drinking. Using the case of PDW in Jakarta, Indonesia, we call for theorizing the politics of PDW through a situated Urban Political Ecology (UPE) analysis of the wider urban water distributions in which it is inserted. We do so in order to interrogate the unevenness of individual “choices” for securing safe drinking water, and highlight the ambiguity of PDW’s impact on inequalities in access. We first review research on PDW supply to specify how dominant theoretical approaches used for understanding PDW supply through analyses of the individual making “choices” for drinking water are power neutral, and why this matters for achieving equitable water access. We illustrate these points through a case study of PDW consumption by low income residents in Jakarta, and then identify how a situated UPE framework can help attend to the uneven societal relations shaping different socio-material conditions, within which individual “choices” for PDW are made. For Jakarta, connecting choices of the individual to power relations shaping geographies of urban water access and risk explains the rise in PDW consumption by low income residents as a situated response to the uneven exposure of poorer residents to environmental hazards. We conclude with reflections on how this can inform interventions towards more just distributions of safe drinking water.

Removal Of Arsenic

The current situation of Pakistan is reaching to an alarming situation in the context of polluting water bodies as well as groundwater due to various natural and anthropogenic activities, which can be foreseen for shortage and unavailability of safe and healthy drinking water for the population. The greater part of Pakistani individuals (almost 60%) living underneath the neediness line so they don't move toward perfect and safe drinking water supplies. Arsenic is one of the hazardous metals presents in various territories of Pakistan as well as in various zones of the world. Its essence strokes individuals' wellbeing by sullying the water. This experimental adsorption study emphasizes on the arsenic removal from drinking water by utilizing cost-effective adsorbent called "Iron Coated Chitosan Beads (ICCB)". This technique is more useful and effective when contrasted with different removal methodologies to remove arsenic from groundwater. ICCB was utilized and it was discovered a compelling and productive adsorbent for the removal of arsenic from groundwater. From all clump tests, the removal level of arsenic is achieved from 79 % to 98%. These results demonstrated that ICCB can be utilized as a productive adsorbent material for the removal of arsenic from water.

Affordable access to safe drinking water is essential to community health, yet there is limited understanding of water insecurity among Native Americans. Therefore, the focus of this paper is to describe Apsáalooke (Crow Indian) tribal members’ experiences with water insecurity. For Apsáalooke people, local rivers and springs are still vitally important for traditional cultural activities. We interviewed 30 Native American adults living on the Crow Reservation in Southeastern Montana. Participants answered six open-ended interview questions about their water access, costs of obtaining water and changes in their domestic and traditional water uses. Participants emphasized how the use of water has changed over time and described the complex challenges associated with addressing water insecurity in their community, including the importance of considering the spiritual and cultural impacts of water insecurity on health. Water insecurity is a growing global problem and more attention and efforts are needed to find appropriate and affordable solutions.

Informality is pervasive in Tanzania’s rural waterscape, but not acknowledged by development partners (donors and beneficiaries), despite persistent warnings by development scholars. Informality is thus the proverbial elephant in the room. In this paper, we examine a case of superior rural water access in two geographical locales—Hai and Siha districts—in Tanzania, where actors not only acknowledge, but actively harness informality to provide access to water to rural populations. We employ concepts from organization and institutional theory to show that when informal programs and related informal sanctions/rewards complement their formal counterparts, chances for achieving the Sustainable Development Goals (SDG) target 6.1 ‘By 2030, achieve universal and equitable access to safe and affordable drinking water for all’ are significantly increased.

Safety Of Drinking Water

Abstract Although many kinds of materials for water purification are known, easy-to-use methods that ensure the safety of drinking water for rural populations are not sufficiently available. Sorbent-embedded sheets provide methods for the easy removal of contaminants from drinking water in the home. As an example of such a sorbent-embedded sheet, we prepared a Linde type A (LTA) zeolite-embedded sheet (ZES) and examined its Pb(II) removal behaviour. Different amounts of LTA were added either as powder or as ZES to 0.3 mM Pb(NO3)2 solutions containing 2.5 mM Ca(NO3)2, in which the ratio of the negative charges in LTA to the positive charges in Pb(II) (LTA/Pb ratio) ranged from 1 to 20. After shaking, the mixtures were centrifuged to remove the powder, while the ZES was simply removed from the mixture by hand. The LTA powder removed more than 99% of the Pb(II) from the solution at all LTA/Pb ratios within 1 h, while the ZES removed >99% of the Pb(II) at LTA/Pb ratios of 2 and higher; at the highest LTA/Pb ratio of 20, the ZES removed >99% of the Pb(II) in 30 s. Therefore, the use of appropriate sorbent-embedded sheets enable the facile removal of contaminants from water.
