U.N. looking at septic tanks as source of cholera outbreak in Haiti

Investigators from the U.N. are looking for the source of the Haiti cholera outbreak and that search has led them to septic tanks. Cholera, a bacterial infection which is often transmitted through contaminated food or water, hasn't been recorded in Haiti since the early 20th century, yet has recently spread throughout the country. So far, over 4,000 people have been sickened, and the source of the outbreak is under investigation. The search thus far, has led to septic tanks as a possible source.

Currently, the U.N. is investigating a Nepalese peacekeeping base as a possible source of the outbreak. Associated Press (AP) reports broken and overflowing septic tanks on the base and septage following from the tanks down to a nearby river, where people regularly bathe, drink and wash clothes. The U.N. has taken samples from the broken septic tanks to test for cholera. To read the full AP story click here.

While it remains to be seen whether the Nepalese base is the source of the cholera outbreak, this story highlights the, sometimes extreme, dangers that poorly functioning septic systems can have on human health. The impact of a malfunctioning septic system can be large and wide-spread if untreated waste is allowed to enter groundwater or surface water. To prevent contamination of groundwater and surface water resources, and protect your health and the health of your neighbours, make sure your septic system is in good working order; have regular pump-outs, get your tank inspected, conserve water and don't abuse your system.
