Field volunteers who are trained in environmental health using appropriate technologies engage the community to address the needs of clean water, healthy sanitation, and efficient cookstoves. Community-centered and maintained improvements include:
- Potable water systems providing clean water to entire communities.
- Fuel-efficient stoves which reduce wood fuel consumption and respiratory illnesses caused by cooking over an open flame.
- Purifying water sources using locally available filter systems.
- Compost latrines.
- Environmental health education and organizing to ensure the community knows how to use and maintain these improvements.
