News & Insights Groundwater: Making the Invisible, Visible World Water Day 2022 The theme for this year's World Water Day, is groundwater. Out of sight, under our feet, groundwater is a hidden treasure that transforms lives. In fact, Just a Drop uses groundwater to develop safe water solutions in four of the six countries we work in, namely India, Nicaragua, Uganda and Zambia. We asked Nancy Stone, hydrogeologist and expert volunteer, to make groundwater and its impact a bit more visible for you, our amazing Just a Drop community! Bring Safe Water a Step Closer For this year's World Water Day, why not join the Just a Drop community by becoming a regular donor? Women and girls around the world walk 6km on average to collect water. Just £6 can support a family in Cambodia with safe water and sanitation for one year. And by this time next year, your regular £6 gift could have helped 12 families!
