Abstract
The work contained in this report is a follow-up and confirmation of the data collected during Part I of this campaign in 2001. Part I involved the sampling of 42 wells in the northern half of CFB Gagetown to characterize the underlying groundwater flow dynamics as well as the chemical characterization of the groundwater quality. This early work, which is to be found in DRDC Valcartier technical report TR 2003-016, identified a possible low-level contamination of some areas of CFB Gagetown by energetic materials. As well, seven elements in thirty-two wells were found to be higher than specified in the Canadian Council of Ministers of the Environment (CCME) guidelines. Part II of this campaign was performed in October 2002 at CFB Gagetown, and is the focus of this report. Eighteen monitoring wells were installed, developed and sampled during Part II, largely in the southern area of the Base. In addition, 33 of the wells installed during Part I were re-sampled, and fourteen bivouac wells sampled. The data collected was used to confirm and expand the piezometric map of the aquifer underlying the Base, and to confirm and expand the analytical results of Part I. Aluminium, manganese and iron were again found in concentrations above the CCME guidelines, confirming the findings of Part I. However, energetic materials were not detected in any of the ground or surface water samples, contrary to results from Part I. Perchlorates, which have been detected in the groundwater on American
