Department of National Defence, CFB Rivers, Manitoba
NOTRA conducted a Geophysical Survey and UXO Clearance and the
former CFB Rivers, Manitoba. The overall project goal was to
extend the clearance operations conducted in 2007 and remove
the risk of EO/UXO encounters for the general public while
providing defendable documentation detailing the measures
taken to remove all EO/UXO to a depth of no less than half
(0.5) meter.
NOTRA provided personnel, equipment/materials, expertise and
consulting services to carry out a UXO Survey and Clearance
which included: mobilization, soft prove out (SPO), a 100%
coverage geophysical survey of approximately 21 ha piece of
property (using a 0.5m Depth of Exploration), geophysical data
analysis, anomaly reacquisition, subsurface clearance of
potential MEC, hard prove out (HPO) and removal of MD and
N-MD.
With the overall project goal in mind, NOTRA mobilized
equipment and personnel to the site to undertake investigation
and clearance operations. NOTRA combined the use of hand held
detectors with EM61 survey techniques to complete the project
on schedule, budget and to the requisite standard of quality
required by the Department of National Defence
(DND) and Defence Construction Canada (DCC).
The NOTRA team selected an approach based on our experience
and understanding of the former CFB Rivers, UXO survey and
clearance requirements. The company designed an approach
focused on quality and transparency that provides DCC and DND
with defendable processes and procedures for demonstrating
that data quality objectives (DQO) were met.
The
geophysical survey and UXO clearance conducted on the site has
allowed DCC/DND to more clearly define the extent of the
property which was impacted by munitions debris. While the
highest concentration of munitions debris was located in the
center of the surveyed area, numerous munitions debris items
were recovered right up to the fence line (property limit) at
the north end boundary of the surveyed area. No live EO/UXO
were ever recovered during the 2008 or 2007 geophysical survey
and UXO clearance projects, however, approximately 90 MD items
were removed from the site.
