Westport Elementary School in the Ceres Unified School District has a filtration system on campus to remove uranium after high levels were discovered in the well water several years ago. It was one of the schools tested for other metals, including lead, arsenic, copper and zinc, and came up within acceptable levels on all and below detection level on the arsenic. Signs at the various drinking fountains on campus tell students the water is safe to drink. Jeff Jardine jjardine@modbee.com
