Thanks. I can agree with your conclusions regarding pilot shutdown of EW-15 and EW-16 and approve that action. Please let me know what your timeline is. I will add the corrections to the memo for the file.

Mavis,
1) I will produce a figure showing water levels/capture zone for EW-2 without pumping at EW-15 and EW-16 and will send in a later email;
2) The "-5" on the contour near EW-16 is a misprint -- should be "5" -- oops!;
3) EW-18 is a lower TSA well -- pilot shutdown of this well approved on 11/3/2009.

Charlie, I have reviewed the pilot shutdown proposal for EW-15 and EW-16 and had a couple of questions.
What would the capture zone for EW-2 look like if EW-15 were not pumping? The text indicates that it would encompass the area of >5 ug/l. I don’t have in front of me whether EW-18 is still pumping but I assume it is and is a also a lower TSA well.
The figure on page 5 shows the contours around EW-16 and the 5-contour looks like a -5. Is this just a misprint?
Thanks.
