NORM is the norm in Louisiana waters

AZ:
There are three basic classes of pollutants in the waste stream: benzene elements, heavy metals, and NORM (Normally Occurring Radioactive Material). The benzene properties tend to stay on the ocean's surface and are burned off by sunlight but the heavy metals and NORM "fall out" over large areas around the rigs where they are consumed by benthic (bottom feeders) organisms and work their way back up through the food chain. Eventually the toxins enter the human food chain through seafood consumption.

Mercury, thallium, lead, arsenic, are just some of the heavy metals in produced water but the real danger comes from NORM, radium-236 and radium-238. The sheer amount of NORM pumped into the Gulf from produced waters since off shore drilling began is mind boggling. In fact, all we can do is estimate because the EPA or LDEQ (Louisiana Dept. of Environmental Quality) has not done a comprehensive study on the effects of produced waters in the Gulf of Mexico. In 2003, the EPA was supposed to have conducted a comprehensive EIS (Environmental Impact Study) on the effects of the produced water discharge in the Gulf of Mexico but the EIS was never executed (under W. Bush admin.) and the permitting process was turned over to the LDEQ. The LDEQ then eased the restrictions on rig owners allowing them to actually increase the amount of produced water they were discharging into the waters of the Gulf of Mexico.
More here, including a video interview I can't view at the moment.
