Thank you.
My next question is likely for the municipal officials.
Most major municipalities treat the water before it goes into the drinking water system. When that is so, the water contains no lead when it comes out of the filtration plant.
If owners of private systems do not change their part of their pipes and they let the water flow from the taps in the bathroom, from the shower, or from anywhere else in the house, they are returning water containing lead to the public system. But over the years, have you seen a drop in the concentration of lead in the water to be treated before it is put into the drinking water system?
Mr. Craik, can you answer that?
