We found that research confirms the presence of E. coli, Salmonella, and Hepatitis A. These are just a few of the nasty things you might encounter.
Sewage and Bacteria Exposure

Chemical Contamination
Industrial sites and urban areas contribute chemicals. Pesticides, herbicides, and heavy metals can be present. Exposure can happen through skin contact or inhalation. Long-term exposure to these toxins can have serious health consequences over time.
