PFAS chemicals have been detected in blood, both humans and animals, worldwide, as well as in food products, water, air and soil. Ultraviolet Light (UV Light) can be used as a pathogen reduction method against some microorganisms. Aeration is an in-line point-of-entry process that reduces the concentration of volatile organic compounds. EFFECTIVE AGAINST: Aeration water treatment is effective for management of dissolved gases such as radon, carbon dioxide, some taste and odor problems such as methane, and hydrogen sulfide, as well as volatile organic compounds, like MTBE or industrial solvents.It is also effective in precipitating dissolved iron and Saving Lives, Protecting People, guide for water treatment while hiking, camping, and traveling, use a hand sanitizer that contains at least 60% alcohol, Centers for Disease Control and Prevention, National Center for Emerging and Zoonotic Infectious Diseases (NCEZID), Division of Foodborne, Waterborne, and Environmental Diseases (DFWED), Como prevenir los microbios transmitidos por el agua en casa, Choosing Home Water Filters & Other Water Treatment Systems, Step 2.
