Water Testing Results

About water testing

Fixtures were tested at each school sites below. Each table displays the frequency of use for fixtures that had lead test results that were above the regulatory action level of 15 parts per billion (ppb) by San Francisco Public Utilities Commission (SFPUC). Learn more about action levels.

The California Water Board testing protocol is that when a water test level from a fixture comes back at or above 15 parts per billion (ppb), the fixture is considered to be “above the EPA action level” and retested. If the second test comes back lower than the EPA action level, then a third test is performed to determine whether or not the fixture needs to be shut down and remedied.

Actions taken

When testing reveals that a school has one or more fixtures with lead test results that are above the regulatory action level, SFUSD responds with the following actions:

  • Fixtures with test results above regulatory action level are taken out of use.
  • SFUSD ensures sufficient water supply for the school, including providing bottled water if needed.
  • SFUSD develops a remediation plan for the school, which may include replacing the fixture(s) in question.

Frequency of use for water sources as rated by school administrators

  • High: likely used by many at least once per day
  • Moderate: possibly used once or twice a week by a small number of students
  • Low: this is not a highly trafficked area; few if any drink from this fixture

About Action Levels

The U.S. Environmental Protection Agency sets an action level of 15 ppb for lead in drinking water. According to State Water Resources Control Board recommendations, If the lead level in a first-draw drinking water sample collected on a drinking water outlet at the school campus after stagnations is:

  • Higher than 15 ppb
    The corresponding drinking water outlet should be re-tested to confirm the initial result. Upon confirmation of the initial result, the drinking water outlet should be either addressed to mitigate the lead problem or permanently removed from service. Any corrective actions implemented by the school for that drinking water outlet should be re-tested to confirm the lead level in water is not higher than the action level.

  • Not higher than 15 ppb
    There is a strong indication of insignificant exposure to lead at that particular sample location and the corresponding drinking water outlet can be returned to use with no further water testing.
