Description
|
|
In
this course, students learn the correct way to implement low-flow
purging and sampling using both a dedicated pump and, as seen here,
a portable pump.
|
Students
learn how to successfully deploy a PDBs in a ground-water monitoring
well used for no-purge sampling during a field session
|
|
This is an intensive
one-day course on the U.S. EPA-approved purging and sampling procedure
referred to as low-flow purging, low-stress purging, Micropurging
or minimal drawdown purging, AND the new methodology referred to
as No-Purge or Passive Sampling. This field course explains why
and how low-flow procedures and no-purge sampling produce dramatically
improved and more consistent sampling results and significant cost
savings. Students learn what low-flow purging and no-purge sampling
are; what types of sampling equipment are compatible with low-flow
purging and no-purge sampling; what critical parameters must be
measured in the field; how to determine if low-flow purging or no-purge
sampling will work for a specific site; and the economics of low-flow
purging and no-purge sampling. A 2-hour field session allows students
to apply all of the techniques involved in low-flow purging and
no-purge sampling.
