Engineered sand zaps storm water pollutants: Technology could help provide local source of drinking water for parched communities -- ScienceDaily: Engineers have created a new way to remove contaminants from storm water, potentially addressing the needs of water-stressed communities that are searching for ways to tap the abundant and yet underused source of fresh drinking water. The mineral-coated sand reacts with and destroys organic pollutants, providing a way to help purify storm water percolating into underground aquifers, creating a safe and local reservoir of drinking water for parched communities.
