In 1988 and 1999, OEHS conducted studies of lead in drinking
water. Both studies concluded that daily flushing of drinking
fountains for 30 seconds would reduce lead concentrations below
the Environmental Protection Agency’s (EPA) recommended
guidelines. To implement these recommendations, the District
developed a policy for flushing drinking fountains (Reference
Guide 3930.3 Daily Flushing Requirements for
Non-Refrigerated Drinking Fountains).
In 2008, the District initiated a comprehensive study to sample
all drinking water sources at all schools. The U.S. EPA
estimates 15.5% of California schools have drinking fountains
that exceed the action level of 15 PPB (parts per billion) for
lead in drinking water on the initial draw and 6.5% of schools
exceed the action level on the second draw.
Drinking water fixtures that exceeded the action level of 15 PPB
on the first draw were retested after flushing for 30
seconds. If the results were still above 15 PPB the fixture was
shut off until corrective actions to reduce lead levels had
been implemented.
Drinking water testing results will be posted on the OEHS
website as they become available. Copies of reports may also be
requested from OEHS at (213) 241-3199.
