A judge in Michigan found enough evidence to charge three officials in connection with the scandal related to high levels of lead in Flint’s water supply.

Busch is a district supervisor in Michigan’s Department of Environment Quality, Prysby an engineer at the DEQ, and Glasgow a Flint utilities administrator.

Here’s more from the Detroit Free Press, which reported on the charges on Tuesday:

Officials believe the city got artificially low lead readings because they didn't test the homes most at risk — those with lead service lines or other features putting them at high risk for lead. Among those to be charged is a City of Flint official who signed a document saying the homes Flint used to test tap water under the federal Lead and Copper Rule all had lead service lines — a statement investigators allege was false.

[Attorney General Bill] Schuette is to announce felony and misdemeanor charges against at least two, and possibly as many as four people, according to two other sources familiar with the investigation. The investigation is ongoing and more charges are expected, sources said.

Flint is under a state of emergency after elevated levels of lead were discovered in its water supply after the source of the city’s drinking water was switched in 2014 from Lake Huron to the Flint River. In the meantime, the city’s residents are using filters and bottled water. Governor Rick Snyder is trying to assuage concerns over the quality of Flint’s water, saying on Tuesday that he’d drink filtered water from the city for a month.
