Jacobs Engineering Group Inc. JEG has been contracted by Environmental Management Operations EMO to develop and implement a Groundwater Monitoring Well Assessment Plan for Canal Creek in the Edgewood Area of Aberdeen Proving Ground APG-EA. The task will be performed under the provisions of Master Agreement 071914-A-D7, Task Order 142133. The project consists of assessing the condition of existing groundwater monitoring wells in the Canal Creek Area prior to a groundwater sampling program. The following Work Plan describes the technical approach that will be used to conduct field work for the project. Integrity of some monitoring wells installed at APG-EA has come into question because of problems with well completions that were detected in wells at the O-field Study Area during a recent sampling event. Because of this, EPA and APG-DSHE officials have requested a well integrity assessment for a percentage of 168 monitoring wells installed at the Canal Creek Study Area14 by USATHAMA, 152 by USGS. Results of the well assessment will be used to determine if these wells were completed in a fashion that minimizes the potential for either cross-contamination of aquifers or leakage of water from the surface into the well.
