Water Research
Research to Protect Our Water Resources
As changing climate patterns, biological and chemical contaminants, and aging water infrastructure systems threaten the availability and quality of water, communities and aquatic ecosystems will increasingly rely on advances in science and technology for resilience. EPA’s water research supports solutions that ensure adequate supplies of clean water resources to protect our health and livelihood, protect and restore watersheds and ecosystems, and strengthen our economy.
