@oralloy,
water treatment is a "Batch science" . They had water corrosion treatment with the Detroit system, When Flint changed its source ater, did it assume that all those polymers and treatment schema happened "By themselves?".
It needs to be carefully monitored. As you recall, they water company was FAKING its routine sampling. Fortunately it was some EPA wag that saw the impossibility of the data that was being presented. (PH, alkalinity, and corrsion index numbers just didnt jive).
I was always amazed at how dumb the water dept was to think that they could get away with it. THEN , I was more amazed when they did get away with it for so long.
Have any indictments come forth ??
Ida fired the chemistry and engineering staff of the water dept as well as the public health officials (I feel that there hadda be criminal collusion somewhere, too much **** was covered over by Water Dept or DEQ)
The DEQ needed to clean house and the EPA regional "Safe Water Staff" needed to be punished or fired. ( Ever since Bush and Obama began cleaning house and not filling in retirement positions any longer, the EPA doesnt seem to inspire public health actions and nobody seems to give a **** what the EPA even is all about) We can always go back to the 1960's when ,with no environmental agencies, this was a common thing.
