UNC Water and Health Conference (October 2017)
At the 2017 UNC Water and Health Conference in Chapel Hill, North Carolina, Jamie Green presented a poster on an assessment of Exposure to Fecal Contamination in Informal Settlements and Formal Neighborhoods of Siem Reap, Cambodia. The CGSW’s Sanipath Tool was used to assess the risk of exposure to fecal contamination in 5 environmental pathways in 5 neighborhoods (3 formal and 2 informal settlements). Overall, there were large variations in exposure risks within formal neighborhoods and informal settlements. Results show that raw produce posed one of the greatest risks of exposure to fecal contamination across all five neighborhoods (100% of adults exposed to dose ranging from 7.59E05 to 1.78E07 CFU/month from produce). Participants in all neighborhoods reported bottled water and well water as main sources of drinking water, while few reported drinking municipal water. No E. coli was found in municipal water, while bottled water and well water had moderate amount of E. coli. The lowest dose of exposure for floodwater was found in the only neighborhood with a drainage system (4.79E02 CFU/month). Results from this study provide evidence for decision makers to prioritize efforts to reduce exposure to fecal contamination in Siem Reap.
