Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage. [1][2] It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed.
What is Water Quality? What is in that water that you just drank? Is it just hydrogen and oxygen atoms? Is it safe for drinking? All water is of a certain "quality" (and you can't tell by just looking), but what does "water quality" really mean? Water full of dirt and grime might work fine for a tomato plant but would you want to drink it?
All water is of a certain "quality" (and you can't tell by just looking), but what does "water quality" really mean? It can be thought of as a measure of the suitability of water for a particular use based on selected physical, chemical, and biological characteristics.
Key points. The better your water quality, the less likely your water is to make you sick. The quality of your tap water depends on where it came from and how it has been treated. Water utilities must monitor water quality and meet safe drinking water standards.
Monitoring water quality is thus complex and expensive; testing for nutrients, turbidity, or bacteria gives you no information on metals, organic pollutants, or pH. This section provides a brief introduction to the most important water-quality parameters.
Water quality can be classified into four types—potable water, palatable water, contaminated (polluted) water, and infected water. What are the 5 core parameters of ambient water quality?
WHO produces a series of water quality guidelines, including on drinking-water, safe use of wastewater, and recreational water quality. The water quality guidelines are based on managing risks, and since 2004 the Guidelines for drinking-water quality promote the Framework for safe drinking-water.
Water safety and quality are fundamental to human development and well-being. Providing access to safe water is one of the most effective instruments in promoting health and reducing poverty.

Water quality is a measurement of how suitable water is for a particular use, like drinking or irrigation. Drinking water quality standards are based on the health effects that are likely to occur if a person is exposed to poor water. Industrial or agricultural water supplies will require different water standards.
