NOAA report offers little local data on BP spill's impact, Tri-Parish Times, February 2, 2011:
[NOAA spokesman Gary Petrae] said that NOAA began its direct investigation in August 2010 and that by Oct. 23, 2010, NOAA researchers had had taken a total of 39,000 samples that resulted in hundreds of thousands of data points and by the end of their study found no deposits of liquid MC252 oil in sediments beyond an unspecified area of Louisiana shoreline. Additionally, there were no benchmark levels of dispersants found.
"The findings were such that less than 1 percent of the water samples and approximately 1 percent of the sediment samples exceeded EPA aquatic life benchmarks," Petare said. Water samples that did exceed EPA limits, he claimed, were not from the BP Deepwater Horizon spill.
"There are about 3,000 natural seeps in oil and natural gas in the Gulf of Mexico and they put out about 12 million gallons of oil and natural gas in the Gulf annually..."
