Why is water quality important in an aquatic ecosystem?

It affects the amount of phytoplankton that are present in the surface water, which is critical because phytoplankton naturally take in and lock up large amounts of free carbon and release oxygen to the environment. Marine water quality also influences the ability of fish and marine mammals to grow and reproduce.

What does water quality depend on?

Background. Scientists measure a variety of properties to determine water quality. These include temperature, acidity (pH), dissolved solids (specific conductance), particulate matter (turbidity), dissolved oxygen, hardness and suspended sediment. Each reveals something different about the health of a water body.

What are the effects of water quality?

If drinking water contains unsafe levels of contaminants, it can cause health effects, such as gastrointestinal illnesses, nervous system or reproductive effects, and chronic diseases such as cancer.
