Access to safe water and sanitation systems is foundational to healthy communities. Many communities without running water rely on unprotected water sources, which frequently become contaminated and expose communities to waterborne diseases. In addition, reliable access to safe water is a necessity for safe and effective medical care, in order to properly maintain sanitation and reduce the risk of infection in hospitals. H2O4ALL community health initiatives include water access for hospitals and health centers, sanitation and hygiene projects such as latrines and washing facilities, and ensuring at-risk populations such as seniors and young children are protected from the dangers of unsafe water.
