Just talked to my sister, and they think it will still be days before they get the all clear for water. Huge impact on businesses, schools, hospitals. The ban on using the water supply to water livestock has been lifted, but she thinks it is probably still unknown if it is actually safe for livestock. Also says there is a lot of conflicting information and it is impossible to know what might be accurate and what is not. Essentially, no one knows if there is a safe dilution level for this chemical, and there is no way to remove it from the water supply through water treatment.

She's a water resource engineer - spent her career designing water treatment and waste water treatment plants. Some people are starting to use the water for bathing in spite of the ban, but she considers that pretty stupid, given that no one knows. She says in the absence of any good science, they won't be using the water until the chemical is completely out of the water system. I'm glad she's up there at Mom's. Mom would be in a real pickle post surgery without her just now.

The following article is an eye opener, pointing out that little is actually known about many chemicals manufactured and stored along our rivers that may enter the water supply.

What is 'Crude MCHM'? Few know.
