The most recently available testing , from the second half of 2018, puts the lead in Flint’s water at 4 parts per billion. That’s well below the level, 15 ppb, that the federal government currently regards as dangerous for public health.

No amount of lead in water is safe, but the lower level in Flint represents a substantial improvement over the 27 ppb reported by the Virgina Tech Water Study at the peak of the crisis in April 2015.
