Description:"Sample collection in the field faces many challenges including, but not limited to, the equipment and materials that can be brought safely into the field. Field teams will often reuse sample collection gear by cleaning it between sampling sites to prevent cross-contamination. Decontamination protocols for equipment used to collect samples for organic contaminant analysis range from a simple water rinse with scrub brush application to more involved measures that include soap and/or the use of various organic solvents. The efficacy of six different field cleaning protocols for sediment sampling tools was evaluated in a controlled laboratory setting using two different sediments (predominantly sand and silt) that were dosed with weathered Deepwater Horizon oil (i.e. "Slick B oil"; collected from surface slicks on June 19, 2010). Percent (%) residual total extractable hydrocarbons (TEH) and percent residual polycyclic aromatic hydrocarbons (PAH) were measured to evaluate the relative effectiveness of the various protocols in removing oiled sediment from the stainless steel materials. Cleaning protocols encompass scenarios where decontamination is limited by resources, supplies, and time, as well as scenarios where resources, supplies, and time are not a factor"--Executive summary.
