<br /> Hi Vicki,
<br /> This was the well configuration proposed in GTI's letter dated October 12, 2012 and approved in your letter
<br /> dated October 19, 2012. However; MW-106, SW-101 and DW-31448 Hwy-333 were removed from the rotation,
<br /> as we no longer have access to these wells. I did see I left a well out and I've corrected that. I also changed the
<br /> wording to make it clearer. Here is the edited protocol. If approved,would you like me to submit an amended
<br /> work plan?
<br /> Current Quarterly Groundwater Monitoring and Sampling
<br /> The current groundwater monitoring regime is summarized below. Ground Zero recommends continuing
<br /> this protocol.
<br /> First and Third Quarters
<br /> • Quarterly performance monitoring: MW-1, MW-2,MW-7, MW-101, OW-1 and OW-2 "z
<br /> • Groundwater analysis and DTW measurements: MW-1, MW-2, OW-1 and OW-2 (TPHg, BTEX,
<br /> MTBE and 1,2-DCA by EPA method 8260B)
<br /> Second Ouarter r
<br /> • Quarterly performance monitoring: MW-1, MW-2,MW-7, MW-101, OW-1 and OW-2
<br /> • Groundwater analysis and DTW measurements: MW-1, MW-2, MW-4, MW-5, MW-7, OK
<br /> 1 ' 0 , OW-1, O ` 'and domestic well 1697 Durhfn Ferry Road (TPHg, BTEX, MTBE and

<br /> Hi Eric,
<br /> Thank you for informing me that AS-7 has not been installed.
<br /> I still have questions about the wells that are being checked for depth-to-water. What is the rationale for choosing
<br /> these wells each quarter?
