How can seasonal changes affect water quality in small systems?

Seasonal changes can significantly impact water quality in small systems by introducing contaminants and altering the composition of water sources. For example, during warmer months, higher temperatures can promote the growth of algae and other microorganisms, leading to increased turbidity and the presence of harmful byproducts. Rainfall can lead to surface runoff, which might carry pollutants such as fertilizers, pesticides, and sediments into the water system, further contaminating the water supply. Additionally, seasonal transitions can affect the physical and chemical properties of water, such as pH and dissolved oxygen levels.

These variations in water quality necessitate vigilant monitoring and adjustments by water system operators to ensure that the water remains safe and meets regulatory standards for public health. Thus, understanding and managing the effects of seasonal changes is crucial for maintaining the integrity of water systems.
