National attention in the Flint water crisis has focused on how children were poisoned with lead-tainted drinking water.

Now questions are being raised about a new $285 million pipeline that is supposed to begin supplying the city's water after construction is completed later this year.

Without the pipeline, the Flint crisis probably would not have happened. The contamination occurred when the city temporarily switched from its longtime water supplier in Detroit to a temporary source, the Flint River, until it could connect to the new pipeline.

A Michigan governor's task force has recommended a review of the pipeline's approval. And the county official who led the pipeline project is coming under scrutiny. Pipeline supporters say the project will provide cheaper, more reliable service after years of steep rate hikes.
