Water quality trends refer to long-term changes or patterns observed in the physical, chemical, biological, or radiological characteristics of water bodies. These trends can indicate improvements or deterioration in water quality over time.
Eutrophication: Eutrophication is an increase in nutrient levels (such as nitrogen and phosphorus) in a water body, leading to excessive growth of algae and other aquatic plants. This can result in oxygen depletion and harm the ecosystem.
Dissolved Oxygen: Dissolved oxygen refers to the amount of oxygen gas dissolved in water. It is an important indicator of water quality because aquatic organisms rely on dissolved oxygen for respiration.
pH: pH is a measure of how acidic or basic a substance (in this case, water) is. Changes in pH can affect the health and survival of aquatic organisms.
