Giardia:

Giardia is a protozoan that can cause diarrhea, vomiting, and cramps. It can also cause weight loss and dehydration.

Cryptosporidium:

Cryptosporidium is a protozoan that can cause diarrhea, vomiting, and abdominal pain. It can also cause respiratory problems, such as pneumonia.

It is important to note that these are just a few examples of the health effects of contaminants in tap water. The specific health effects of exposure to bio-contaminants will vary depending on the type of contaminant, the level of exposure, and the individual's susceptibility. If you are concerned about the potential health effects of bio-contaminants in your tap water, you can take a number of steps to protect yourself and your family. One option is to have your water tested. This can be done through a private company or through a local government agency. If the water tests positive for bio-contaminants, you can take steps to filter or treat your water. There are a variety of water filters available on the market, and some water utilities offer free or discounted water filters to their customers. Another option is to drink bottled water. However, it is important to note that not all bottled water is created equal. Some bottled water brands contain high levels of contaminants. It is important to choose a bottled water brand that has been independently tested and certified to be safe.

Finally, you can also advocate for changes to your local water utility. This could include calling for the utility to test for more bio-contaminants or to take steps to remove contaminants from the water supply.It is important to remember that tap water is generally safe to drink.

However, it is important to be aware of the potential health effects of contaminants in tap water and to take steps to protect yourself and your family if you are concerned.

Here is a more comprehensive and informative answer to your question about the controversial chemicals used in water treatment:

Water treatment is the process of removing contaminants from water to make it safe for human consumption. The specific chemicals and processes used in water treatment vary depending on the source of the water and the types of contaminants present.

Some of the most common chemicals used in water treatment include:

Chlorine:

Chlorine is a powerful disinfectant that is used to kill bacteria, viruses, and other pathogens in water. It is also used to oxidize organic matter and other contaminants. Chlorine is a relatively inexpensive and effective disinfectant, but it can also produce harmful byproducts, such as trihalomethanes (THMs). THMs are suspected carcinogens and exposure to high levels of THMs has been linked to reproductive and developmental problems.

Chloramine:

Chloramine is a disinfectant that is formed by reacting chlorine with ammonia. Chloramine is less volatile than chlorine gas, so it is more effective at disinfecting water distribution systems. However, chloramine is also less effective at killing some pathogens, such as Cryptosporidium and Giardia. Chloramine can also produce harmful byproducts, such as nitrosamines. Nitrosamines are also suspected carcinogens.

Ozone:

Ozone is a powerful oxidant that can be used to remove a variety of contaminants from water, including organic matter, iron, and manganese. It is also used to disinfect water. Ozone is a very effective disinfectant, and it does not produce harmful byproducts. However, ozone is more expensive to produce and use than chlorine or chloramine.

Aluminum sulfate:

Aluminum sulfate is a coagulant that is used to remove suspended solids from water. It is also used to reduce the concentration of dissolved organic matter. Aluminum sulfate is a relatively inexpensive and effective coagulant, but it can also produce aluminum hydroxide sludge. Aluminum hydroxide sludge is a hazardous waste that must be properly disposed of.

Ferric chloride:

Ferric chloride is a coagulant that is similar to aluminum sulfate. It is often used in conjunction with aluminum sulfate to improve the removal of suspended solids and dissolved organic matter. Ferric chloride is more expensive than aluminum sulfate, but it produces less sludge

Polyelectrolytes:

Polyelectrolytes are polymers that are used to enhance the coagulation process. They help to bind suspended solids together and make them easier to remove from the water. Polyelectrolytes are generally considered to be safe, but some people have concerns about the potential health effects of long-term exposure. The use of these chemicals in water treatment is controversial because of the potential health risks associated with exposure to them. However, it is important to note that the risks associated with exposure to water treatment chemicals are generally very low. The benefits of using these chemicals to produce safe drinking water far outweigh the risks. Water utilities carefully monitor water quality and implement appropriate treatment processes to remove pollutants. Consumers should also be aware of the potential risks and take steps to protect themselves, such as boiling water before drinking it if they are concerned about the presence of chemicals. In addition to the chemicals listed above, there are a number of other chemicals that can be used in water treatment. The specific chemicals used will vary depending on the specific needs of the water utility.

Some of the other chemicals that can be used in water treatment include:

Fluoride:

Fluoride is a mineral that is added to drinking water in some communities to prevent tooth decay. Fluoride is generally considered to be safe and effective, but some people have concerns about the potential health effects of long-term exposure to high levels of fluoride.

Lime:

Lime is a chemical that can be used to adjust the pH of water and to remove hardness. Lime is generally considered to be safe, but it can produce a white precipitate that can make water less palatable.

Activated carbon:

Activated carbon is a material that can be used to remove organic matter and other contaminants from water. Activated carbon is generally considered to be safe, but it can be expensive to produce and use.

The decision of which chemicals to use in water treatment is a complex one. There are a number of factors to consider, including the potential risks and benefits, the availability of other water treatment chemicals, and the cost of treatment. It is important to weigh all of these factors carefully before making a decision.
