Extremely doubtful. If the test was accurate, I would be looking at other sources. Did they repeat the test to make sure it was correct. Is you daughter staying in a daycare or pre-school in an older building? If you are really concerned about the pinball, you could have yourself checked for lead. It is doubtful that it is the problem that they had in Flint. There, the problem arose from the older pipes in the homes with lead in them that leached the lead into the water when the acidity of the water changed when the source of the water changed. The city itself was not putting out lead-laden water.
Things to look for are are sources of peeling older paint and toys, etc from questionable sources.
Best of luck. Hope you can get to the bottom of it.
