Instant lead testing debunked by Virginia Tech professor

FLINT, MI (WNEM) -

A man’s video has been shared 2,039 times and has nearly 200,000 views.

In the video, he uses a digital water tester, testing the water coming from his Flint home, a water filter, and water bottles.

When he tests the water coming from his tap, using a digital reader, and compares it to his filter, it appears the filter is worse.

But according to Dr. Marc Edwards, the Virginia Tech researcher who help bring attention to the lead issue in Flint’s water, those digital readers can’t be trusted for accurate readings.

“There’s no real reliable way to test for lead that is simple and easy,” Edwards said. “You have to use a very expensive instrument such as those that the EPA have, the state has and we have at Virginia Tech.”

Edwards said those tests provide false negatives and false positives for lead.

Concerns over filters aren’t new, especially in the Flint water crisis. But Edwards said as long as they are NSF certified filters, they will remove 99.3 percent of lead from water.

“We tested them at Virginia Tech – we tried everything imaginable to really challenge those, to get lead through the filters and they just work,” Edwards said. “As long as you’re drinking water from those filters, you can be sure you’re protected.”
