Quarterly Groundwater Monitoring Report
May 2011— July 2011
Injection Well Permit #WI0700012
Tank Farm Remedial Action System
Beaufort Co.
Dear Qi:
Please find the subject groundwater monitoring report attached. This includes the sampling and reporting
requirements of the above referenced permit, Part V, Section B 1 as well as the reporting requirements of
the overall Tank Farm Remedial Action Plan. Enclosed are: a) Form GW-59 for injection well CIW7 and
monitor well MWTF 1 CR, b) piezometer level monitoring field sheet, and c) the summary operational and
maintenance report.
Note: Inadequate head was available in CIW7 during the sampling event. The injection well water was
sampled upstream from the WLCT. Historical sampling shows that data collected from CIW7 and WLCT
are identical.
Please do not hesitate to contact me at [phone] if you have any questions regarding this information.
Sincerely,
D. Daniel Winstead III
