Hi Blake,

For the proposed groundwater monitoring well sampling described in the Work Plan for the ATI East Shop, the Division did
approve sampling for dissolved metals.
However, as you mentioned, the Division would prefer sampling for total metals.
If you are able to sample for total metals, please let me know.

Thank you,

Team,

Paige recently mentioned that we want total metals for groundwater samples now. However, the DWRMC-approved
work plan states we will filter those samples. Should I filter the metals groundwater samples or not?
