From The Lakewood Sentinel (Glenn Wallace):
A recent sunrise saw Joe Centeno, a maintenance plumber with Jefferson County schools, already busy at work at Arvada’s Peck Elementary, changing out water cutoffs, connector lines and fixtures in hopes of improving the water quality.
The district’s effort to test water outlets at all 158 schools for high lead levels found 10 elevated level sites at the 50-year-old school — a sink in the teachers’ lounge, three sinks in the kitchen and six classroom sinks, some of which had bubbler drinking attachments.
“This is the guinea pig,” Centeno said. “We’ll see if this works.”
His best guess as a plumber was that the repairs should fix the problem, based on the scattered lead readings, as opposed to schoolwide contamination that would have required more extensive and expensive replumbing.
