The Howard County School System has released updates regarding lead levels in the water of schools across the county, including Centennial High School.
Since September 2018, the HCPSS Office of Environment has tested the water in all Howard County schools for lead.
In Centennial’s initial testing, which was done in November 2018, ten water sources tested positive for lead levels above 20 parts per billion (ppb).
The board quickly took action, assessing the problems within the fixtures and deciding how to proceed.
On January 31, 2019, Centennial High School released their first two reports, which laid out the remedial action taken against two of the affected outlets.
An additional six reports were released on March 27.
Of the eight faucets the county fixed to improve the lead levels, four of them were replaced, as the outlet itself was the cause of the lead.
For the other four, more drastic measures were taken, including three being totally removed from the water system in Centennial.
The last outlet was left alone due to the levels dropping to 5.3 ppb and 1.7 ppb in separate additional tests.
The HCPSS Office of Environment is still working to fix the remaining two water outlets, which, as of now, are not in use.
