Detailed explanation-1: -Commonly Occurring Waterborne Pathogens Other pathogenic microorganisms, such as Legionella, Naegleria fowleri, Vibrio spp., and Pfiesteria, occur naturally in waters and can multiply in response to environmental changes such as increased water temperature (Legionella) or excess nutrients (Pfiesteria) (ASM 1998).
Detailed explanation-2: -Waterborne illness is caused by recreational or drinking water contaminated by disease-causing microbes or pathogens. Of note, many waterborne pathogens can also be acquired by consuming contaminated food or beverages, from contact with animals or their environment, or through person-to-person spread.
Detailed explanation-3: -Disadvantages of Boiling Water Boiling water can only remove bacteria, meaning it will not remove harmful substances such as chlorine and heavy metals such as lead from tap water. Boiling tap water with lead actually concentrates this contaminant making it more dangerous than if left alone.
Detailed explanation-4: -Boiling the water kills microorganisms such as bacteria, viruses, or protozoans that can cause disease. Boiling makes the tap water microbiologically safe. Bring tap water to a full rolling boil, let it boil for one minute, and let it cool before using.
