Recycled water production is strictly reviewed and monitored by federal and state regulators. Every day, Monterey One Water tests its recycled water to ensure water quality meets the high standards for food crop irrigation. Laboratory analysis monitors for both process control and compliance assessment.

The permit required to produce recycled water for crop irrigation includes continuous water quality sampling and monitoring. This testing is conducted by certified laboratory and operational personnel and is defined in the Waste Discharge Requirements Order No. R3-2018-0017 (PDF) issued by the California Regional Water Quality Control Board, Central Coast Region for NPDES No. CA0048551.*

Laboratory analysis requires looking for more than 100 substances in the water including microorganisms, pesticides, herbicides, asbestos, lead, copper, petroleum products, and by-products of industrial and water treatment processes. More than 20,000 annual laboratory tests ensure the safety of this important water supply for vital agriculture land.
