District Completes Lead Testing
Testing, and follow-up testing on the only faucet that exceeded levels in its initial test, did not find any instances of lead levels exceeding the District’s 10 ppb action limit. However, there were four locations where levels fell between 5 – 10 ppb. Even though samples in those locations did not exceed the District’s action limit, maintenance staff still took steps to replace the fixtures in those locations, which included:
- The Family Center – A faucet and supply lines were replaced in a non-drinking sink in the Red Room that tested at a level of 8.29 pbb.
- Captain Elementary School - A faucet and supply lines were replaced in a non-drinking sink Room 68 that tested at a level of 5.06 pbb.
- Meramec Elementary School – An existing drinking fountain outside Room 4 was replaced with a new model (with filter cartridge). The existing fixture tested at a level of 6.81 pbb.
- Clayton High School - A faucet and supply lines were replaced in a non-drinking sink in Room 118E (library work room) that tested at a level of 9.84 pbb.
