San Diego Unified School District is expected to announce new water testing policies Thursday in connection to the lead-tainted water found on several local campuses. The three-year program will involve testing all water outlets used for human consumption at district facilities. The sampling project will include early childhood education facilities and central offices, which were excluded from testing earlier this year. Water was at tested at 207 schools on district property beginning in April. Results showed 19 percent of the schools had some level of lead in the water.
