By any normal examination, nothing seemed off. The oil couldn’t be seen or smelled, but lab tests on the oysters and soil showed the contaminant levels were through the roof. “We didn’t see anything unusual. That was kind of the disturbing part when we got the results back,” said Lower Mississippi River Keeper Paul Orr, from the Water Keeper Alliance.
Orr went to several sites in the Gulf of Mexico with a team of researchers to take samples of the soil, plants, and sea life. The team has results from two locations and is still waiting on the rest. “When the numbers came back, I was quite surprised they were so high,” Orr said.
What they were looking for were polynuclear aromatic hydrocarbons (PAHs)—carcinogenic contaminants from the BP oil spill. Since PAHs carry a kind of fingerprint, BP can be traced as the source of some of the contaminated areas. “We did find it in large quantities in the soil sediment, as well as in vegetation and organisms—oysters and some in the crabs,” said Wilma Subra, a MacArthur Award-winning chemist who conducted the tests.
Subra said that other contaminants were found along with the PAHs, and “we’re not talking parts-per-million or parts-per-billion.” “It was there in substantial concentrations. If you had to test it to determine whether or not that area would be applicable to being harvested, those concentrations were way over the concentration you would ever even consider.”
