"If Columbia is able to test for DSS or DOSS, the chemical compound that proves Corexit 9500 is being used, then they have inside information that the rest of us don't have. There is no way to determine if Corexit 9500 is used unless you have a list of ALL the ingredients in Corexit. The Gov. which regulates the EPA has left off several of the chemicals that make up Corexit." I know this because all we have is the MSDS to go by. This leaves most research scientists in the dark."
Overall, the water sample contained a surprisingly high concentration of propylene glycol between 349 and 417 ppm (v/v) indicating the presence of an even higher level of Corexit (of which propylene glycol is only a part). These results are consistent with the evaporation of volatile components from oil to leave tarballs and an especially high concentration of the dispersant on the surface of the water. Toxicity tests have shown that a concentration of 25 ppm of Corexit 9500 in oil-free water can kill most fish and only 2.6 ppm of Corexit has the same effect in the presence of dispersed oil (which is the case with the analyzed sample). The considerably higher Corexit surface water concentrations implied by the propylene glycol concentrations in the analysis suggest that humans may receive a harmful exposure to these chemicals and dispersed oil by swimming in the water or inhaling the sea spray. Overall, this water analysis suggests high Corexit concentrations in surface water near New Orleans and suggests a public health hazard that should be taken seriously along the entire Gulf Coast.
News Five collected samples of water and sand from Orange Beach, Gulf Shores, Katrina Key and Dauphin Island. To our eyes, the samples appeared normal, until we took them to a local lab to be tested.
Water and sand along Alabama's coast should contain no more than five parts per million of oil or petroleum, according to Bob Naman, an analytical chemist. But, the samples we collected tested much higher.
From 16 ppm to 221 ppm, our results are concerning. Even more disturbing is what happened to a sample collected from the Dauphin Island Marina near oil containment boom.

Here in Canada we do not allow our governments to messwith our environement. We may only have 30+ million people but at least when we discover the PTB lying to us we can throw their sorry arses out.
