3/10/2020 Heather called about a possible cyanide monthly average violation. On their in house spreadsheet the 4 samples are over their limit. However on the DMR it is below. I stated since the DMR is below their limit that is the official average. There were 2 of the 4 results that were no detect that are being averaged as 0. CARL BERG
