“…55 Nawalparasi is the most severely affected district with 11.69% of the wells reported to exceed As concentrations of 50 ppb, leading to alarming As-induced health effects, such as arsenicosis. 58,59 Frequent outbreaks of water-borne diseases, such as typhoid and cholera, have been reported due to the contamination of water sources. Typhoid and diarrhea cases increased during the previous decade.…”

“…Arsenic has been observed in the groundwater of all 20 Terai districts and in four hilly districts, occurring due to natural geochemical processes, with concentrations as high as 2620 ppb documented in the Rupandehi district. , Nonetheless, such a high As concentration is reported to be rare, as the latest database of 1.1 million tube wells (2003–2008) reported As concentrations of >50 ppb in 1.73% of the samples and concentrations between 10 and 50 ppb in 5.37% of the samples . Nawalparasi is the most severely affected district with 11.69% of the wells reported to exceed As concentrations of 50 ppb, leading to alarming As-induced health effects, such as arsenicosis. , …”

Access to water, sanitation, and hygiene (WASH) has been a challenge to south Asia’s rapidly growing and climate change-sensitive region. Nepal, a water-abundant country, faces obstacles to fulfilling the highly prioritized WASH Sustainable Development Goal 6 (SDG 6). This review offers details about Nepal’s WASH status from 2000 to 2020 with regard to the challenges Nepal had in delivering reliable WASH services to the people, as well as opportunities for a sustainable way forward, and provides insights that can be applied to other developing countries. From analysis of national-level assessments, estimates point toward healthy progress in extending WASH access to the population. However, large inequalities persist at the subnational level between urban and rural residents, between poor and rich residents, and between genders. Many local constraints such as a lack of long-term infrastructural capacity to provide and maintain WASH services, financial issues, and institutional and policy incompatibilities are some of the key factors that technical considerations and private sector involvement could address. We also propose roles for Nepal’s central, provincial, and local governments for identification and adaptation to the undeniable risks of climate change. Furthermore, there is a need to capitalize on the potential opportunities for developing a much-needed robust and climate-resilient WASH sector in Nepal, safeguarding the rights of future generations to safe and clean water.
