California Beaches – 2005

California beachGBB conducted litter surveys using the Institute for Applied Research methodology at 75 beach sites along the California coast.  These surveys were conducted for a confidential client.  The standard IAR methodology was modified to include individual litter items with an area between one-half and one square inch.  (Note: The standard IAR methodology surveys litter with an area greater than one inch.)  This includes items such as cigarette butts.  These small items were found to contribute a significant portion to litter.  Other findings indicate that storm drain outfalls and off-shore sources, such as ships, also contribute significantly to beach litter.  Wood and other organic material were found in significant quantities as well.  Organics are of particular interest because of bioactivity in the ocean environment.
