Last week I posted a chart showing the average lead levels in Flint’s water since the beginning of the year. This is an easy chart to update, so I figure I’ll make it a weekly feature on Monday morning for a while. As usual, I’ve eliminated outlier readings above 2,000 parts per billion, since there are very few of them and they can affect the averages in misleading ways. The average for the past week was 8.08. The average since mid-January is 10.07.
