It doesn't. They meant that their plan to take action if the lead levels rose was a workable one, i.e. they were able to execute the plan. They also said that lead levels in their children never rose. The sentence might have been more clear with an 'and' after the comma, although it was clear enough in context (IMO) without it.

- _dark_matter_ 5y agoI don't remember all the details now, but the test we were using was extremely sensitive. I believe it was detectable within 1/20 of maximum allowable levels in children.
