Most of us are familiar with the oil spill off the coast of Louisiana.  There's now a web site to track the spill's dimensions.   Developed by NOAA with the EPA, U.S. Coast Guard, and the Department of Interior, the site, http://www.geoplatform.gov/gulfresponse/,  offers you a “one-stop shop” for spill response information.  The site integrates the latest data the federal responders have about the oil spill’s trajectory with fishery area closures, wildlife data and place-based Gulf Coast resources — such as pinpointed locations of oiled shoreline and current positions of deployed research ships — into one customizable interactive map.

The Center for Disease Control also has a page dedicated to the potential effects of the oil spill should it appear on your local coast line, here. The CDC mentions four possible categories that you may be exposed to hazardous substances related to the spill:

• Air
• Water
• Food
• Dispersants
