Water Quality Data

Our primary responsibility is to process wastewater so it is safe for reintroduction into the environment. Our state-certified laboratory is staffed with an experienced team of water quality specialists who monitor the integrity of our treatment processes and final effluent of our three types of discharge. Regulations help safeguard public health and the environment by setting strict operational and water quality standards.Monterey One Water staff prepare and submit monthly, quarterly, semi-annual, and annual water quality reports to regulators at the California Water Boards.
