"Tap water" is the water that comes out of your faucets. It is provided by whatever local water source you are connected to. This can be municipal water lines, springs, artesian wells, or even cisterns. The exact minerals and chemicals found in tap water will vary due to the many different methods in which water is treated to make it safe for human consumption.
Water treatment methods include filters, precipitants, reverse osmosis, ultraviolet light (UV), chlorination, ozonation, and exposure to bactericides such as metallic silver or iodine.
The taste of tap water will depend on the minerals remaining after treatment, including carbonates, silicates, and salts. "Hard" water includes substantial minerals, while "soft" water contains compartively few. City water supplies frequently add the same sort of minerals to their systems as are found in some bottled water. This, along with aeration, improves the taste of tap water. (Although obviously most of it is being used for other than drinking purposes.)

City tap water will differ from a tap in the country, because city tap water is "recycled" (usually from a river or lake), while sources outside a city are wells.
Another factor is that different pipes kinds of pipes are used. Alhough iron levels vary, there is generally more iron in well water.
Water used over and over, often by several areas that are downstream. Everything you flush (waste, prescription medicines, shampoos) all can end up in a public water supply, and it receives varying amounts of treatment before going back into the environment. Many treat water with chlorine on its release as well as on its intake to a water sysytem.
Tap water can be full of chemicals including chlorine and aluminum. These chemicals are not meant for human consumption but occur either naturally in water sources (due to the composition of the surrounding soil), or are added by cities and town to remove harmful bacteria or unpleasant tastes. In order to drink "pure" water, you need to either filter it or buy pure spring water.
What else can I help you with?
Is city tap water a substance or a mixture?
City tap water contains many substances dissolved in it. So city tap water is a mixture. Different types of gasses, substances can be dissolved in this water.
How do certain substances affect the pH level of tap water?
Substances like acids (e.g. lemon juice) can lower the pH level of tap water, making it more acidic. Conversely, substances like baking soda can raise the pH level of tap water, making it more alkaline. The pH level of tap water can be altered by adding these substances in small quantities.
is tap water in a glass pure substances or mixture?
Tap water is not a pure substance. Water has particles in it. Some tap water also contains fluoride. Distilled water has all of the particles taken out of it and is considered pure water.
What are some chlorine substances?
chlorine bleach, tap water, salt, swimming pool water.
Is Tap water element compound or mixture?
Tap water is a mixture. It is water with some impurities.
What microorganisms can be found in tap water?
Protozoa.
What type of mixture is tap water?
Unfiltered tap water is a pure substance
Why is tap water dangerous?
Tap water becomes dangerous if the amount of chemicals in it gets too high. Metals such as lead, iron, cadmium, and arsenic can be found in tap water. Chemicals such as nitrate, mercury, and fluoride can also be found. Tap water can contain microorganisms like bacteria or parasites that make you sick.
Which will freeze the faster between salt water sugar water and tap water?
Tap Water because adding substances to the water (salt or sugar) reduce the rate at which water will form ice crystals, making it freeze at a lower temperature.
Is tap water a solution colloid or suspension?
Tap water is a solution because it is a homogenous mixture where the solute (dissolved substances) is evenly distributed in the solvent (water). Unlike colloids or suspensions, the particles in tap water are molecular in size and do not settle out over time.
Does sea water boil at higher temperature than tap water and why?
Yes. Dissolved substances increased the boiling point.
Who has a high proficiency system for tap water cleaning?
Tap water cleaning can be found easily by the use of a Brita filter. In addition, tap water cleaning can be had by contacting the local environmental agency.
