Water quality refers to the chemical, physical, and biological characteristics of water that determine its suitability for various uses, such as drinking, swimming, and aquatic life. Water quality parameters are measurements used to evaluate the conditions of the water. Common water quality parameters include:

Measures the acidity of alkalinity of water

DO is the amount of oxygen dissolved in water. It supports the respiration of fish and other organisms.

Turbidity refers to the clarity or cloudiness of the water. High turbidity can affect the aesthetic quality of water and may indicate the presence of pollutants.

Temperature

Water temperature can affect the health of aquatic organisms and the overall ecosystem. Different species have specific temperature requirements for survival and reproduction.

TDS is a measure of the total amount of dissolved substances in water, including minerals, salts, and organic matter.

Nutrient levels, such as nitrate and phosphate

Nutrients are essential for the growth of aquatic plants and algae. However, excessive nutrient levels can lead to eutrophication, which can harm aquatic life and degrade water quality.

Presence of contaminants

Water quality can be affected by various contaminants, including heavy metals, pesticides, bacteria, and viruses.


Since private wells are not regulated, it is important for a well owner to regularly test the water quality of private wells to ensure that it is safe for consumption. Testing the water quality can help identify any contaminants or issues that may affect its safety.
