FLINT, Mich. (AP) — The election of new City Council members might break an impasse and lead to a long-term deal over drinking water in Flint, Michigan.

The state has been asking a federal judge to allow Flint's mayor to bypass the council and approve a 30-year agreement with the Great Lakes Water Authority. It's part of a strategy to get the city past a lead contamination crisis.

Judge David Lawson said Thursday he'll postpone a hearing until Nov. 20, a week after five new council members take office.

Lawson had ordered the former council to come up with a long-term water source by Oct. 23. Instead, the council asked for more time.

Flint used the Flint River for 18 months until fall 2015. The water wasn't properly treated, causing elevated lead levels.
