After identifications of arsenic contamination in Pakistan, lot of technological based arsenic mitigation interventions were carried out which could not last longer due to non-availability of filtration media and running spare parts of arsenic removal tanks units in the local market. The in-depth performance analysis of arsenic removal technology (ART) units, clay pitchers and PUR sachet was carried out which showed un-sustainability of these interventions. The main reasons are lack of awareness, illiteracy and unfavorable socio-economic conditions which make the end users in villages/rural areas the most vulnerable to the adverse impacts of any type of contaminated water and own the installed arsenic removal interventions. Therefore, before taking up any arsenic removal project, it is worthwhile to explore those interventions which are compatible to local socio-economic environments. Deeping boring options have been found best suited, as most of the agricultural practices are dependent on ground water- at shallow depths. The soil analysis at deeper depth will help in ascertaining the causes of arsenic contamination due to presence of arseno-pyrites or due to leaching of sustained applications of pesticides & fertilizers. Therefore, in case of absence of arseno-pyrite sediments at deeper depths. Then the best option for provisioning of arsenic free water is deep boring. The active participation of the communities who are the intended beneficiaries of arsenic mitigation is vital for the success of the programme. Lack of awareness and generally unfavorable conditions are also obstacles to mobilizing communities to get the best out of community-based programmes and projects. Therefore, a well designed protocol for alternative water supply has been evolved which will help in provisioning of sustainable arsenic free water.
