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 Governor Rick Snyder.

‘‘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. ‘‘But the most important I think right now is to start the focus on the assessment and providing 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, but has not said how much.
