There was a meeting between Facilities and Ms. Thompson this morning. Though I was not invited, I did exchange a few pleasantries when I passed by Claudio Bazzano. He was carrying a large binder with an image of gray-ish water in a cup, and a title: Mary Hooker Water Quality. The existence of this binder put me in mind of my FOIA request, as yet unanswered. I did ask Claudio if they had checked on potential copper problems at other schools, a question that he had not answered in my email request. He indicated that "we want to get this one right first."
I learned some things about water chemistry. It is important to know whether water is corrosive--meaning metals leach from the plumbing, or scale-forming--meaning that minerals deposit and prevent leaching. I had been puzzled by the fact that MDC's water is of neutral pH. So how could non-acidic water be corrosive? It has to do with two other variables: water hardness, and alkalinity. MDC's water is quite soft, and low in alkalinity, therefore corrosive even at neutral pH.

the guys testing the copper in are schools water did not respond...... is the copper in are schools good or is it bad? and that are water could be corrosive meaning that metal or copper leaks in from the pipes making are water unsafe to drink this happens along the (like through the pipes and others) BY KB AND PK
