Verification
Verification is a series of activities and measurements 
that enable the effectiveness of a particular operation
on site to be assesssed, and hopefully confirmed.

Verification and validation have slightly different
meanings. Verification is a series of activities and measurements
that enable the effectiveness of a particular operation
on site to be assessed, and hopefully confirmed. Validation
is a series of activities and measurements that have been
carried out to ensure a particular technique is fit for its
general purpose. Verification and validation typically
encompass a range of information, matching actual to predicted
findings: the remediation effectiveness; cost; use of
resources (personnel, reagents, energy etc.); generation
of wastes and emissions; impact on soil/water properties
(e.g. pH, redox).

Typically a remediation technique
will need to have some validation for a potential user to
take it seriously. For any given remediation project the
site owner and regulator will want to have the effectiveness
of the remediation verified.
