Easy iron test with guava leaves! Can be tested with a little guava leaf, iron in your food water? Guava leaves are crushed by hand and placed in a glass of water after some time, the color of water with excess iron turns black. On the other hand, the color of iron-free water remains as clear as before. Our WASH group members are taught this simple, cost-effective, and eco-friendly technique to test water quality so they and their families don’t suffer any health risks!
