Water Quality Program

The goal of the Water Quality Program is to ensure safe water for drinking and recreational use. Unsafe drinking water can lead to a bacterial or viral infection, particularly in vulnerable populations such as young children. Maintaining safe conditions in recreational areas, such as swimming pools, helps prevent persons from drowning and the spread of infectious diseases.

  • Monitor sewage discharge to the ocean and bay.

  • Provide immediate support and response to events that raise health implications and concerns.
