Calculations and
Methodology
A site contamination assessment protocol must be followed to evaluate hazardous
material pollution.
An example of such a protocol is the ASTM Environmental Site Analysis Process, which
includes E 1903 – 97 Phase II Environmental Site Assessment.
A Phase I analysis includes the identification of the potential for contamination through
former land uses and / or through preliminary site analysis
A Phase II analysis includes the completion of site surveys to determine the presence
and extent of contamination on a site.
A Phase III assessment demonstrates the remedial steps to be taken to decontaminate,
or safely encapsulate, the site prior to construction.
Asbestos qualifies as contamination where it occurs in the ground.
A remediation strategy must be developed specific to the contaminated site; guidance
can be found in the Model Procedures for the Management of Land Contamination (CRL
11).
A suitably qualified professional in the context of this credit must be an individual with
a degree covering contaminated land remediation, a minimum of five years work
experience and regular practice in the field.
