Additional research must be done to ensure safety of pit latrines, new study says

Pit latrines are one of the most common human excreta disposal systems globally, and their use is on the rise as countries aim to meet the sanitation-related target of the Millennium Development Goals. Strong evidence supports the use of these basic toilets as a way to improve human health. However, improperly designed pit latrines can actually allow disease-causing microbes or other contaminants to leach into the groundwater.
