Maintenance and Operations


The safety and health of our students and staff across Alpine Union School District (AUSD) is one of our top priorities. With this in mind, we wanted to notify you that the lead testing of our schools’ water supplies has been conducted and completed.

The drinking water at all of our schools has been found to be safe. All of our schools met the EPA guidelines for safe drinking water.

The process began on June 23, 2017 when AUSD officially requested that testing be completed at all AUSD school sites. On September 13, 2017, the Padre Dam Municipal Water District began taking water samples from each school site which included outdoor drinking fountains and indoor kitchen areas

On October 24, 2017, Padre Dam Municipal Water District reported that the results for all of our schools were complete and that all values tested were less than the State’s 15 parts per billion (ppb), therefore requiring no further testing.

Copies of each site’s results can be found by clicking the links below.

Who is the water provider for Alpine Union?
Water for Alpine Union Schools is provided by the Padre Dam Municipal Water District. As the water provider, they are required to comply with state and federal regulations and, as such, conduct numerous water quality tests and produce related reports.

Who conducted the testing?
A water specialist from the Padre Dam Municipal Water District conducted the testing at all our sites.

Were all school sites tested?
Although there are no regulations that require public schools to test drinking water, we developed a plan with our water providers to test all school sites throughout the District to ensure we are continuing to provide safe drinking water to our students and staff.

The water testing in AUSD began on September 13, 2017.

What is considered allowable test results?
The current standards were developed and implemented by the United States EPA in 1991. The standards state that the Action Level (AL) for lead is 15 ug/L. This is defined to mean "micrograms per liter" or "parts per billion". One part per billion is equivalent to about one drop in an Olympic-sized swimming pool. The Department of Drinking Water regulations state that any results at 15 ug/L or less are below Action Level.
