LANSING, Mich. -- Michigan lawmakers directed another $28 million on Thursday to address Flint's lead-contaminated water supply, allocating money for bottled water, medical assessments and other costs for the financially struggling city.

The quick and unanimous approval by the House and Senate came just over a week after the funding was proposed by Gov. Rick Snyder, who is expected to sign it quickly.

"We obviously have a number of issues that we have to deal with, whether it's infrastructure, whether it's folks having to pay for water that obviously is undrinkable," said Senate Minority Leader Jim Ananich, D-Flint. "But the most important I think right now ... is to start the focus on the assessment and the providing of services."

This is the second round of funding enacted since the crisis was confirmed in the fall, bringing the total allocated to nearly $39 million. Snyder has promised to put forward more funding for Flint in his upcoming annual budget proposal -- when he also will detail plans for a one-time $575 million surplus -- but has not said how much.

It is unlikely to be as high as the up to $400 million figure mentioned in Congress on Thursday. Senate Democrats proposed that amount in emergency federal aid to Flint, with a requirement the state match the spending on Flint pipes, dollar for dollar.

"This is a state responsibility," Michigan Sen. Gary Peters said at a news conference at the Capitol. "The state broke it. They need to fix it."

Flint's water became contaminated when the city, under emergency state management, switched from the Detroit municipal system and began drawing from the Flint River in April 2014 to save money.

State regulators failed to ensure the new water was treated properly, and lead from pipes leached into the water supply. Some children's blood has tested positive for lead, which has been linked to learning disabilities, lower IQ and behavioral problems.

The Board of State Canvassers rejected petitions Thursday to recall the Republican governor over his handling of Flint's water. Meanwhile, Progress Michigan, a liberal group critical of Snyder, released emails showing the state was sending water coolers a year ago to employees at a state office building in Flint.

That occurred after Flint announced it briefly had flunked some drinking water standards apart from the current lead contamination.
