Water Testing Related to Martinez Refining Company Incidents
The City of Martinez Water Plant has been tracking recent events at the Martinez Refining Company.
The Water Plant uses multiple treatment processes to ensure its drinking water meets State standards. These processes include coagulation, flocculation, sedimentation, ozonation, filtration and chloramination. The City also recently completed a major infrastructure project, which significantly improved the efficiency and reliability of the ozonation process. The newly constructed ozonation facility provides reliable disinfection of the drinking water and removal of wide range of contaminants, including metals. If any significant release of metals makes its way into the drinking water supply, it would be readily removed by all of the above-mentioned treatment processes, in addition to being oxidized by ozonation.
To ensure that drinking water has not been affected by the refinery's major chemical release, we test the water at the treatment plant and distribution system for the contaminants (metals) of concern after incidents occur.

Improving Your Drinking Water
Ozone System Upgrades Project is Completed
On October 25, 2021 the Martinez Water System switched from Ozone to Chlorine disinfection of the City’s drinking water to allow for the completion of a capital investment project aimed at improving drinking water quality, increasing operational efficiency and reliability, and bringing the ozone treatment system up to current industry safety standards.
On June 16, 2022, Martinez Water Treatment Plant turned on the newly upgraded ozone facilities and is currently producing high quality drinking water for the community.
California enforces some of the strictest water standards in the country, ensuring our water quality to be among the highest in the world. The Martinez Ozone System Project upgraded the water plant facilities with the latest treatment technologies, increasing the operational reliability, efficiency, and the quality of City’s drinking water. All stages of the project have been coordinated with the regulatory officials to ensure full compliance with State and Federal water standards.
