World Water Week 2018-Stockholm

A Sediment Color Tool has been developed based on the visual color attributes of the shallow sediments as perceived by the local drillers to install community tube wells at targeted safe depths to scale-up safe water access in rural Bangladesh.

In rural Bangladesh, drinking water supply mostly comes from shallow hand tube wells installed manually by the local drillers,The main driving force is tubewell installation.This study was aimed at developing a sediment colour on the basis of local driller’s perception of sediment colour, arsenic (As).concentration of tubewell waters and receptive colour of aquifer elements.
