BACWA is dedicated to working with our member agencies, the state and federal governments, as well as non-governmental organizations to deliver the best information about the water quality of the San Francisco Bay. BACWA works to ensure that water quality information is fully utilized to determine the health and needed protection of the San Francisco Bay. BACWA supports its public utility members understanding of the water quality protection and enhancement needs and requirements.
