I think we're mandated to protect the public and to make the public aware. You certainly need to tell them that there's a problem they may not be aware of. They didn't know about in Surrey, in all these schools. One of the teachers' rooms or staff rooms had six times the lead content.
I could go back in history to the Franklin expedition and what seems to be an exceedances of lead in their drinking water, not through the tin cans that they were using, but through the desalinating system for the steam boiler that was on board that ship. It all went through lead pipes, and the chef used that same water to cook all their meals in. They wandered around the Arctic half-crazed with huge amounts of lead in their systems.
