I am wondering about lead. I have no advance clues that ESM or HPS has a lead problem. In fact, recent data sent to me in a spreadsheet by Claudio Bazzano indicates "no exceedance" for lead tests at each HPS school. Further, he gave specific results for tests at 4 locations at ESM, none of which exceeded the 15 ppb standard. So why do I think it is even worth examining?
