Dear Families and Staff:

This is a follow-up to my December 30, 2016 water test results notification letter. I am pleased to share we have successfully completed remediation work at P.S. 10 - Brooklyn ( Magnet School of Math, Science and Design Technology at 511 7 Avenue, Brooklyn, NY 11215) and on November 08, 2017 and March 28, 2018 and July 26, 2018, the remediated fixtures were tested and the final laboratory results indicate that all samples taken and tested were below the action level of 15 ppb.

On December 02, 2016, every operational source of water, including for drinking or preparing food, at P.S. 10 - Brooklyn was tested for lead. The laboratory results showed elevated levels of lead in 18 of the 99 samples of water taken and tested from outlets in the building. Each affected fixture at P.S. 10 - Brooklyn was taken out of service on December 30, 2016, and the remediation work was completed.

In any building where lead test results show even one water outlet above the action level of 15 parts per billion (ppb), the DOE implements its standard response protocol, under which it removes any drinking or food prep outlet from service, flushes all or part of the system to eliminate water sitting in pipes overnight, replaces equipment and re-tests after the equipment is replaced. As part of our remediation protocols, fixture(s) that were out of order or inaccessible at the time of the initial testing were repaired and tested. All drinking or food prep fixtures are only put back in service once results of laboratory tests are below the action level of 15 ppb.

Out of an abundance of caution, the custodial staff will continue to flush the P.S. 10 - Brooklyn water systems on Monday mornings before school starts in order to eliminate water that has been stagnant in pipes over the weekend and to ensure safe drinking water is available for students and staff.

A more detailed letter related to the testing for lead at P.S. 10 - Brooklyn is attached, and complete test results are posted on the DOE website at https://www.schools.nyc.gov/ schools/K010. Click Data and Reports and look for the Facilities Heading.

Please visit https://www.schools.nyc.gov/about-us/reports/water-safety to learn more about the robust protocol we use to ensure the safety of drinking water in each and every school, as well as to look up water test results for each school.

Thank you for your patience and support and we wish you and your students a wonderful semester.

Sincerely yours,

Elizabeth A. Rose
