The preamble of the Sustainabe Development Goal 6 (SDG 6) is based on the fact that the access to safe water and sanitation together with efficient management of freshwater ecosystems are essential for human health and to environmental sustainability and economic prosperity. Among the specific targets of SDG 6, Target 6.1 is most challenging that concerns achieving universal and equitable access to safe drinking water for all by 2030. 

Specifically mitigation of arsenic in drinking water is a complex issue which involves involvement of a broad spectrum of stakeholders, from policy makers, regulators, facilitators, implementers, to social groups and end users of water. The selection of suitable technology options and the ways they are implemented, have significant impact on the results of the mitigation. In practice, it is important to involve stakeholders from the entire range of the spectrum and at all stages in the process to ensure that the implemented technological solutions are preferred by the end users.

Removal of arsenic from water is a challenging task and requires a thorough knowledge about the raw water quality. The treatment method needs to be improvised considering the water quality prevailing in different regions. The choice of the methods and the scale also varies depending on the in different locations that in urban settings vis a vis the rural settings depending on the target population and socio-economic conditions. In recent years, source substitution has emerged as an important option and should be prioritized and adopted wherever appropriate. However, in areas where source substitution is not a feasible alternative, removal of arsenic becomes inevitable. Thus decision makers should recognize and thoroughly evaluate the impact of replacing or adapting to  treatment practices or adding new treatment technologies for achieving the target arsenic removal. 

Key questions that the panel will try to address include:

In the panel, we focus on a discussion on the overall issue of technology adaptation for community based safe drinking water provisions to meet the challenges of SDG 6.1 in arsenic affected areas. In this panel we would focus on:

1) The aqueous chemistry of arsenic as a governing factor for designing the key processes related to arsenic removal. 
2) Arsenic treatment technologies available
3) Discussion on multifaceted technical, economic and social factors determining the sustainability of the technological solutions.
4) How far have we been able to develop and adapt to technologies for arsenic removal based on low-cost materials on a local scale? 
5) How does the handling and disposal of treatment residuals be improved from a resorce, recovery and resuse perspective?
6) Can we bring in a concept of circular economy  while discussing arsenic treatment residues? 
7) How far the technologies for the provision of provide safe water are accessible, environmentally friendly and adapted to the cultural practices and rules of the population. 
8) What are the indicators with respect to the existing conditions in selected countries such as Bangladesh, Tanzania, China and others and can we develop a common base for rcommendations for scaling?
