USGS Columbia Environmental Research Center Project: Analysis of SPMDs Potentially Exposed to Oil Along the Florida Coast

Statement of Problem: In response to the Deepwater Horizon Oil Spill in the Gulf of Mexico, the USGS and NPS performed pre- and post-oil monitoring studies using SPMDs along the Florida Gulf coast. These monitoring studies will provide a measure of the bioavailable fraction of polycyclic aromatic hydrocarbons (PAHs) and other oil-related chemicals washing up along Florida's shores.

Objectives: The USGS and NPS will deploy the SPMD passive samplers at 18 sites along the Florida Gulf coast prior to and following arrival of oil on the shore. These samplers will be used for approximately 1 month afterwhich they will be returned to the laboratory for processing and analysis. SPMDs from each site will be analyzed for a series of polycyclic aromatic hydrocarbons (PAHs) which may be indicative of petroleum products. In addition, to the specific PAH analysis, a broad screen for "unknown" non-targeted chemicals will be performed.
