Awuju VillageOne of the three poorest villages in the Jinyuan Township
Main Problems: fuel shortages, dermatological scarring & diarrhea, lack of accessible medical care, animal roaming disputes between neighbors.

Xiakeba Village
Main Problems: fuel shortages, injuries during wood collection, lack of toilets with proper evacuation doors, lack of running water in half the village, childhood diarrhea and stomachaches, arthritis.

Common Themes
• Fuel collection, fertilizer, lung pain, and climate change
Root Cause: fuel
• Diarrhea, stomach pain, water collection, non-functional latrines, and community disputes over animals
Root Cause: sanitation infrastructure

• Assess local materials for construction of low-tech water filters
• Additional bacterial analysis
• Document piping materials used in running water projects
• Document fertilizers, pesticides, and rat poisons used in villages
• Collect soil samples near springs and sediment samples from water sources for geological analysis to determine natural metal content
• Qualitative analysis of percent contribution of various species to fecal content of water sources
• Examination of latrine designs and proposal of new methods
