Chris McMeen, a Deputy Water Superintendent with Tacoma Water, was just trying to find new ways to test for lead. The utility tested water in four homes at the service pipes before the meter and not in the home.
”We did that with the intent of finding out if that water quality testing approach would identify if there was lead in the pipe. We sampled it in a way to purposely find lead,” explained McMeen.
Tacoma Water found lead, lots of it. Test results showed some lead levels 25 times higher than the allowable amount. However, KIRO 7 has learned the state Department of Health was not directly involved in the details of the initial four home sampling protocol.
Now the state is asking, did busting into the water line to collect samples actually create the contamination? The utility said it’s seeking that answer. It did speak to an engineer with the Department of Health to provide technical help.
“So if this would be the kind of thing that would be communicated throughout the entire department, I would doubt. It was a technical communication and conversation,” said McMeen.
Federal standards require Tacoma and Seattle to test for lead every three years. But utilities also go above and beyond, like in this situation, testing whenever they feel necessary. Sometimes it’s without direct guidance from state agencies. The Department of Health told me it does not have to be involved with testing beyond federal and state requirements.
”I think it’s important for all utilities to be examining the question is there lead in our systems that we didn’t know about that we haven’t addressed and that’s what we are trying to do here,” said McMeen.
Tacoma Water is testing 10 more homes with the Department of Health directly involved. In the meantime, the follow-up testing of the four original homes is encouraging, showing the water flowing to the homes is safe.
