'Mostly low' lead levels found in testing, governor's office says

DIMONDALE, Mich. – Results from initial water samples collected last week from so-called “sentinel sites” across Flint revealed mostly low lead levels, according to Gov. Rick Snyder’s office.

Sentinel sites are locations that are continuously tested to gather data needed to determine the safety of the water. The sites are determined by the Michigan Department of Environmental Quality, the Environmental Protection Agency and the participation of residents.

Data from the sites -- there are 402 of them --- is being collected over the next seven weeks in two groupings.

Initial testing took place Feb. 10 - 14 in 175 Flint homes. The next round will start this week.

According to the governor's office, the first tests for Group A included 175 samples that were tested for lead and copper. Nearly 90 percent (156) of the samples were below the action level (15 parts per billion). 19 of the samples exceeded the action level. Five homes exceeded 100 parts per billion and were notified and scheduled for a home visit/inspection. Only one home exceeded the action level for copper.

"While initial results are encouraging, we remain concerned about any high levels of lead or copper," Snyder said.

Testing will continue in two-week intervals for each testing group with sample results posted the week following. Homeowners can see results posted online within four to five days, and will receive hard copies within one week.
