Through an initiative from the California Department of Education, the District and EBMUD have tested the drinking water in our schools.
The District is required to report any tested samples that reveal lead levels that are above 5 parts per billion (ppb). One ppb is equivalent to about one drop in an Olympic-sized swimming pool. If any readings are above 15 ppb, the District could be required to continue monitoring the lead levels, treat the water and pipes, educate the public and/or replace the water lines. This is the same level of lead that requires action if found in your home.
With the assistance of EBMUD, we tested all of our schools (except for Middle College High School and Gateway to College which are located at Contra Costa College) in 2017 and received the results, which are posted here.
Additional testing at 14 older schools was conducted in October 2019, and those results are being posted below as the District receives them.
Any fixtures that are found to have a lead level above 4.0 ppb have been taken out of service and will be replaced and retested before being put back into operation.
