Optional Sampling Equipment
An advanced sampling kit may include the
following means to cool samples while still in
the field.

• Small Ice Chest/Cooler
• Expendable Cooling Pack

Sampling Collection Objective

• Obtain a sample for analysis that is
• representative of the spilled oil.

Sampling Plan
COMDTINST M16201.1

• Procedures for taking samples from the
  surface of the water will vary with the sheen
  size and thickness, on-scene weather and sea
  state, the type of petroleum product, and all
  necessary safety precautions. Shipboard
  sample procedures will depend on the number of
  tanks and bilges requiring sampling, and the
  access of those tanks and bilges.

Sampling Procedures
Grab Sampling
Sheen Net Sampling
11
Grab Sampling

• Applicable for thick layers of waterborne films,
  viscous oils, oil globules, and tar balls.
• Also applicable to sampling oil stranded on
  shorelines or oil soaked debris.
• The sample container serves as the sampling
  device.

12
Grab Sampling Procedures

• Procedures for Floating Sample
• 1. Select a sampling site.
• 2. Lower the sample jar into the water and skim
  the oil layer or globules from the water surface
  into the sample jar. Continue the process until
  the sample container is approximately ¾ full.
  Decant if necessary, repeat until oil collection
  is complete.
• 3. Attach sample identification label to cleaned
  jar.

13
Grab Sampling Procedures

• Procedures for Shoreline Sample
• Select a sampling site.
• Using either the lid, tongue depressor, or sample
  jar as a scoop, fill the jar 3/4 full with
  oil-saturated material.
• Attach sample identification label to cleaned jar.

14
Sheen Net Sampling Procedures
TFE-fluorocarbon polymer net

• Sampling is accomplished by slowly dragging the
  sheen net through the sheen and using its natural
  affinity to collect the oil.
• Deposit oiled net into jar.
• Attach sample identification label to cleaned
  jar.

15
Labels

• Use indelible ink, and print legibly.
• Seal sample with oil-resistant tape.
• Electrical tape works very well.
• Do not tape over label.
• Do not seal jar with the label.

Chain of Custody

• MSL recommends using COC labels for criminal
  cases, or when samples are transferred in the
  field from one agency to another (e.g. EPA
  takes sample and transfers it to USCG).
• COC must be continuously maintained from the
  time
• samples are taken.
• If used, ensure COC label data on jars matches
  data on the COC record.

20
Preservation of Samples

• ASTM Standard D 3325

21
Things to Remember

• Quality of samples depends upon sampler.
• Use of Tool Bag for Collecting Samples Be
  Prepared
• Timely turnaround of samples.
• Review All Paperwork and MISLE Activity entries.
