The "15ppb standard" isn't exactly what you think it is. The EPA "action level" (at which point they intervene, and the city is required to fix it) is if 10% of homes have more than 15ppb of lead. So if 10% of homes in Flint had 25ppb that's way above that action level. But, to be clear, being under that action level doesn't mean you are fine. The EPA and CDC explicitly say that no amount of lead in drinking water is safe.
