RemScan used in Rapid Response to Diesel Spill

A significant amount of diesel leaked from a
storage facility in Western Australia and was
captured in an emergency bund area.
RemScan was used to rapidly quantify the
amount of diesel in the bund area, and later
to validate the site remediation works.
During the emergency response, Ziltek
collected soil samples and built a site-specific
calibration model in the instrument to allow
a rapid and accurate determination of Total
Petroleum Hydrocarbons (TPH) C10 to C36.
During subsequent remediation works,
RemScan was used to measure more than
200 samples per day - this allowed the
validation work to be completed in less than
4 days, without the constraints of standard
laboratory analysis turnaround times.
During wet weather, samples were taken to
the site hut for continuous high throughput
processing.
To independently verify the instrument’s
performance, 19 ‘blind’ soil samples were
sent to a NATA-accredited laboratory for
analysis. A very close correlation was
observed between the TPH values predicted
by RemScan and the laboratory data with an
R2 value of 0.997.
Without RemScan, the validation works would
have been extended by several weeks.
The cost savings due to accelerated project
closure and reduced laboratory analysis were
estimated at more than $30,000.
