Thank you.

I'm asking you as well, Ms. Grenier. You put in a dollar figure of $1 trillion.

4:10 p.m.

Executive Director, Ontario Water Works Association

Michèle Grenier

Yes, in the U.S.

In the U.S., do they have programs or models? What have they done to start getting the lead out of the residences there?

4:10 p.m.

Executive Director, Ontario Water Works Association

Michèle Grenier

I'm not entirely familiar with the programs in the U.S. The model is often different when you have a privately owned utility in the U.S. The restrictions with those funds are different from what they are in municipal jurisdictions in Canada.

Thank you.

How much time do I have left?

The Chair Liberal Judy Sgro

You still have three minutes.

Graham, I have a quick question for you. You were saying that once the actual physical lead pipe is removed, the corrosive parts still lead to lead in the water.

November 23rd, 2017 / 4:10 p.m.

Prof. Graham Gagnon

Yes.

4:10 p.m.

Liberal

Gagan Sikand Liberal Mississauga—Streetsville, ON

Okay. It doesn't get eliminated fully when the lead pipe is gone. Basically, is it the parts that leach the lead in there? If we got rid of those parts, would it be 100% removed?

4:10 p.m.

Prof. Graham Gagnon

Yes, and I want to be clear. If you fully remove the lead service line, not partially remove it—

4:10 p.m.

Liberal

Gagan Sikand Liberal Mississauga—Streetsville, ON

No, you fully remove it—

4:10 p.m.

Prof. Graham Gagnon

If you fully remove it, you're in a much better spot. We've seen homes that have returned to much lower concentrations, with 80% removal of lead within three months. You can significantly lower your lead burden by fully removing the lead line.

4:10 p.m.

Liberal

Gagan Sikand Liberal Mississauga—Streetsville, ON

To fully eliminate it, then, you'd have to get rid of the smaller pieces that are left.

4:10 p.m.

Prof. Graham Gagnon

Well, what we talked about previously are the other components inside the home. There might be lead solder or there might be some kind of interesting fixture there, but to have a significant impact on the amount of lead, you have to fully remove the lead pipe.

4:10 p.m.

Thank you.

I'll give whatever remaining time I have to Mr. Hardie.

The Chair Liberal Judy Sgro

You have a minute and a half.

Ken Hardie Liberal Fleetwood—Port Kells, BC

Thank you for that.

Are the personal impacts different according to the age of the person? You're nodding, Michèle. Perhaps you can answer.

4:10 p.m.

Executive Director, Ontario Water Works Association

Michèle Grenier

Thank you.

Children are most at risk because they have the highest metabolic rate per unit mass of body weight, and the neurological effects are more pronounced on younger individuals than they are on older individuals.

4:10 p.m.

Liberal

Ken Hardie Liberal Fleetwood—Port Kells, BC

Is this a cumulative thing, so that the more exposure there is over time, the worse the situation is?

4:10 p.m.

Executive Director, Ontario Water Works Association

4:10 p.m.

Prof. Graham Gagnon

Yes.

4:10 p.m.

Liberal

Ken Hardie Liberal Fleetwood—Port Kells, BC

Speaking of time, you mentioned that lead solder was.... We understood from earlier discussions that they stopped using lead in houses back in the late 1920s. No?

4:10 p.m.

Executive Director, Ontario Water Works Association

4:10 p.m.

Prof. Graham Gagnon

No.
