Water Quality Monitoring

We have conducted lead and copper monitoring for decades, resulting in the collection of thousands of samples. Monitoring programs allow us to look for and document lead in drinking water. We have implemented various monitoring programs to address regulatory requirements or other concerns. A summary of these programs with links to data and additional forms/information is provided below. 

Lead and Copper Rule
The State Water Resources Control Board uses results of water quality monitoring to determine if additional studies or treatment are necessary.  Results of the Lead and Copper Rule monitoring program in the City and County of San Francisco can be found here for the years 2009, 2012 and 2015.

Residential and Commercial Building Testing
San Francisco residents and businesses may request a sampling kit and analysis for $25.00 per tap. WIC participants can request a free lead test.

Lead Tests at K-12 School Campuses in San Francisco
Testing began in April 2017, and will continue until we have completed the testing of fixtures in all San Francisco Unified School District K-12 campus locations and sites. In addition, we have begun testing fixtures, by request, at private, parochial and non-affiliated schools throughout the City. SFPUC test results for schools in San Francisco can be found here.

This template letter is provided to assist you in requesting lead testing at your school site. Please copy and paste this template onto your letterhead, fill in the necessary information, have it signed by the superintendent or head administrator, and return it to our Water Quality Division Director. The completed and signed letter can be submitted via email to adegraca@sfwater.org.
