What are the characteristics of source water that must be considered in treatment planning?

The concentrations of pollutants are critical characteristics of source water that must be considered in treatment planning because they directly impact the design and operation of water treatment processes. Understanding the types and levels of contaminants present in the source water allows water treatment professionals to select appropriate treatment technologies and ensure that the water being supplied meets health and safety standards.

If the concentrations of pollutants are high, certain advanced treatment methods may be required to effectively remove those contaminants. Conversely, if pollutant levels are low, less complex treatment methods may suffice. Additionally, knowledge of pollutant concentrations can help in assessing the overall feasibility, cost, and environmental impact of the treatment options.

Considering just temperature, seasonal variations, or public perception alone would not provide a comprehensive understanding of the source water's quality. Temperature can affect various aspects of water treatment, but it is not a pollutant itself. Seasonal variations may influence the water quality temporarily, but they do not give a complete picture of the overall quality issues that may require treatment. Public perception is important for community acceptance and satisfaction, but it is based on the actual quality of the water and does not affect the technical requirements of treatment processes.
