Field Sampling

Conduct field sampling in accordance with procedures defined in the project work plan, SAP, QAPP, and HSP.

All sampling was conducted in accordance with the procedures described in the project plans.

Contamination Characterization (Groundwater Contamination)

Determine the potential extent of off-post contamination (�2.3.1 of the DQOs for the Groundwater Contamination Investigation, revised November 2003).

Samples for laboratory analysis were collected from selected off-post public and private wells, which are located within a � mile radius of CSSA.

Partially

Replace wells where no VOCs were detected with wells that may be identified in the future, located to the west and southwest of AOC-65 to provide better definition of plume 2.  Continue sampling of wells to the west of plume 1 (Fair Oaks and Jackson Woods) to confirm any detections possibly related to plume 1.

Meet CSSA QAPP quality assurance requirements.

Samples were analyzed in accordance with the CSSA QAPP, and approved variances. A chemist verified all data.

Yes

NA

All data flagged with a �U� and �J� are usable for characterizing contamination.

Yes

NA

Evaluate CSSA monitoring program and expand as necessary (�2.3.1 of the DQOs for the Groundwater Contamination Investigation, revised November 2003).  Determine locations of future monitoring locations.

Evaluation of data collected is ongoing and is reported in this quarterly groundwater report and will be reported in future quarterly groundwater reports.  Additional information covering the CSSA monitoring program is available in Volume 5, CSSA Environmental Encyclopedia.

Yes

Continue data evaluation and quarterly teleconferences for evaluation of the monitoring program.  Each teleconference/planning session covers expansion of the quarterly monitoring program, if necessary.

Project schedule/ Reporting

The quarterly monitoring project schedule shall provide a schedule for sampling, analysis, validation, verification, reviews, and reports for monitoring events off-post.

A schedule for sampling, analysis, validation, and verification and data review and reports is provided in this quarterly groundwater report and will be reported in future quarterly groundwater reports.  Additional information covering the CSSA monitoring program is available in Volume 5, CSSA Environmental Encyclopedia.

Yes

Continue quarterly reporting to include a schedule for sampling, analysis, validation, and verification and data review and data reports.

Remediation

Evaluate the effectiveness of GACs (�3.2.3) and install as needed (�3.2.5 both of the DQOs for the Groundwater Contamination Investigation, revised November 2003).

Perform maintenance as needed.  Install new GACs as needed.

Yes

Monthly maintenance to the off-post GAC systems to be continued by Parsons� personnel.  Quarterly (or as needed) maintenance to the off-post GAC systems by additional subcontractors to continue.  Evaluations of future sampling results for installation of new GAC systems will occur as needed.
