Proof reading is a dead art

According to the 2016 Charlotte, Michigan water quality report published in one of the local paper, more than 10% of the water samples taken in Charlotte, Michigan tested above the action level for copper.

The 2016 report is not available on-line!?!?  The 2015 report is on-line and shows that 90% of the samples are below the action level.  Still, the 90th percentile number is 890, a number that sampling variation could easily tip into non-compliance.  They could have seen this coming.
