This paper tracks lead blood levels of Flint kids from 2005-2016: https://www.jpeds.com/pb/assets/raw/Health%20Advance/journals/ympd/S0022-3476(18)30062-3.pdf https://www.jpeds.com/pb/assets/raw/Health%20Advance/journal... Over this time range lead levels steadily declined with the exception of increases in 2011 and 2015. The 2015 increase brought lead levels back up to where they were in .... 2012 (and still 1/3 of the 2005 level). I'm guessing people just don't drink much tap water. It's hard to reconcile this relatively small change with the calls for intense punishment for those responsible.
