In open areas where raw sewage is present, the unpleasant smell is likely the worst effect, assuming there is no long-term exposure. Particles of raw sewage are able to become airborne, however, and inhalation of these particles causes adverse health effects such as gastrointestinal discomfort, diarrhea, nausea and vomiting. Raw sewage poses the biggest threat to public health when it enters the water supply, where it is diluted and spread much wider than where it originated. While boiling water before consuming it minimizes the risk of waterborne illness, there is a high risk of potentially deadly diseases such as cholera and dysentery from drinking water contaminated with raw sewage.
Contaminants and Diseases
Exposure to raw sewage poses several health threats. People who come into contact with raw sewage need to get tetanus boosters as needed, usually once every 10 years. Parasitic worms frequently present in sewage cause leptospirosis, which is transmitted chiefly by rats. Hepatitis A results from ingesting water or food prepared with water contaminated with raw sewage.
