What is infiltration in the context of water systems?

In the context of water systems, infiltration refers to the unwanted entry of contaminants into a water system. This phenomenon occurs when water from the surrounding environment, which may carry pollutants, enters into water systems such as aquifers, pipes, or treatment facilities. The presence of contaminants can compromise water quality and pose risks to public health.

Understanding infiltration is critical for environmental health specialists, as it highlights the importance of safeguarding water systems against pollutants and ensuring that measures are in place to prevent such unwanted entries. This concept underscores the need for proper design, maintenance, and monitoring of water infrastructure to mitigate the risk of contamination.
