What are the harmful effects of drinking contaminated water?
Effects on Human Health If drinking water contains unsafe levels of contaminants, it can cause health effects, such as gastrointestinal illnesses, nervous system or reproductive effects, and chronic diseases such as cancer.
What do pathogens cause?
A pathogen brings disease to its host. Another name for a pathogen is an infectious agent, as they cause infections. As with any organism, pathogens prioritize survival and reproduction. The human body’s immune system acts as a defense against pathogens.
How do pathogens affect humans?
Sometimes bacteria multiply so rapidly they crowd out host tissues and disrupt normal function. Sometimes they kill cells and tissues outright. Sometimes they make toxins that can paralyze, destroy cells’ metabolic machinery, or precipitate a massive immune reaction that is itself toxic.
What are the 7 pathogens?
Infectious diseases are caused by pathogens, which include bacteria, fungi, protozoa, worms, viruses, and even infectious proteins called prions.
How do you know if your water is making you sick?

What are the 6 food borne diseases?
It is impossible to know about all of these sicknesses, but you should know about the 6 most common foodborne illnesses, known as the “Big 6”—Salmonella, Salmonella typhi (Typhoid), Shigella, E. coli, Norovirus, and Hepatitis A.
How do I know if my water is safe to drink?
Water that’s safe to drink should ideally be clear with no odor or funny taste. One way to tell if water is contaminated is to look for turbidity, or cloudiness. While cloudy water isn’t necessarily dangerous to your health, it could signal the presence of unsafe pathogens or chemicals.
How do you tell if there is bacteria in your water?

- Cloudiness.
- Strange tinting or color.
- Unusual taste.
- Odors of sulfur, rotten eggs or manure.
- Suspended solids.
Are there any pathogens in our drinking water?

Are there any pathogens in Minnesota drinking water?
Bacteria are everywhere in our environment, including Minnesota’s surface waters and groundwater. Some of these bacteria can be harmful to human health. Drinking water with disease-causing bacteria, viruses, or parasites (collectively called pathogens) can make you sick.
Are there any harmful bacteria in tap water?
While some bacteria is useful and harmless, there are bad bacteria that cause disease and illness. Assuming water in your tap has been properly sanitized and disinfected is not always wise. Click To Tweet Water systems degrade over time, older pipes can house bacteria, and your water might have dangerous pathogens.

What kind of diseases can be caused by contaminated water?
Water-related Diseases and Contaminants in Public Water Systems. Contamination of drinking water supplies can occur in the source water as well as in the distribution system after water treatment has already occurred. There are many sources of water contamination, including naturally occurring chemicals and minerals (for example, arsenic, radon,…
