What is causing the odor? Will clean-up activities increase odor problems?
Volatile Organic Compounds (VOCs) found in the crude oil are causing the odors. You can smell most pollutants related to the oil spill well below levels that would cause health problems. During the clean-up process, more odors may be released into the air as the oil is stirred up. The odors will be strongest near locations where crude oil is present.
