Water QC

Water quality monitoring is defined as the sampling and analysis of water constituents and conditions. These may include:

• Introduced pollutants, such as pesticides, metals, and oil
• Constituents found naturally in water that can nevertheless be affected by human sources, such as dissolved oxygen, bacteria, and nutrients

The magnitude of their effects can be influenced by properties such as pH and temperature. For example, temperature influences the quantity of dissolved oxygen that water is able to contain, and pH affects the toxicity of ammonia.
