WASHINGTON — Two years after problems began with the drinking water in Flint, Michigan, and nearly six months after officials declared a public health emergency, a bipartisan congressional effort to aid the predominantly African-American city is idling in the Senate — stalled by the objections of a single senator from Utah.

Rep. Dan Kildee, a Michigan Democrat who represents Flint, says his hometown is struggling while Congress bickers.

“This is not an abstraction. This is 100,000 kids and adults all suffering every single day and it’s pretty frustrating,” Kildee said in an interview. “We will not give up, that’s for sure,” he added, vowing that congressional Republicans “are not going to run out the clock on Flint, Michigan.”

In fact, support for Flint is bipartisan. Michigan’s congressional delegation has unanimously pushed for Flint aid, and Republican Gov. Rick Snyder urged Congress to pass the bipartisan Senate bill “immediately” at an otherwise contentious congressional hearing last week.

Michigan Democratic Sens. Debbie Stabenow and Gary Peters reached agreement with key Republicans last month on a $220 million package to fix and replace lead-contaminated pipes in Flint and other cities.

But the bill remains on hold after Republican Sen. Mike Lee of Utah objected in late February. Lee said Michigan has a budget surplus and does not need federal money to fix the problem.

Stabenow’s frustration has been evident. In an impassioned speech on the Senate floor, she said that as a mother and grandmother, she “can’t imagine the fear and horror” Flint families feel as they are forced — month after month — to use bottled water to drink and bathe.

Like other Americans, Flint residents “assumed that when you get up in the morning and turn on the faucet, when you take a shower or you feed your children, clean water is going to come out of the pipes,” Stabenow said in a March 17 speech. “We all assume that. That is pretty much a basic human right.”

But not in Flint, where the water is tainted with lead.

Flint’s drinking water became tainted when the city switched from the Detroit water system and began drawing from the Flint River in April 2014 to save money. The impoverished city was under state control at the time.

Regulators failed to ensure the water was treated properly and lead from aging pipes leached into the water supply.
