More Flint water samples show elevated levels of lead

FLINT, Michigan. – Recent water testing at the primary schools in Flint have found that an increase in the samples show lead levels above the federal action limit.

The Flint Journal reports the Michigan Department of Environmental Quality determined that the 28 samples tested in February were more than 15 parts per billion of lead. That compares to 20 such samples in January.

Department spokesman George Krisztian says the increase may be the result of changes in the testing conditions, such as the decision to collect samples for flushing lines. Samples collected for the coils tend to have higher lead levels, because the water has been in contact with the pipes for longer.

Krisztian says the overall results are encouraging because they meet the federal guidelines for lead if treated as samples collected by municipal water systems.

Flint’s water was contaminated with lead in 2014 and 2015, when the officials of the water in the river is that it was not good treated.
