BP has stopped using dispersants in the Gulf – for now

We’ve crunched the numbers from the Deepwater Horizon Unified Command press shop, compiling their daily stats for dispersants used in the Gulf of Mexico so far – and the official dispersant numbers for the past week are surprising:

According to official releases, a “very small” amount of  dispersants have been used in the oil spill response since July 16 – and none sub-sea. The statements released by Unified Command on each day since July 15 is exactly the same:

“Approximately 1.84 million gallons of total dispersant have been applied—1.07 million on the surface and 771,000 sub-sea.”

A call to Unified Command’s press center today yielded this comment – “In the last 24 hours, no dispersants have been used.” The staffer then called back and stated “No dispersant has been used sub-sea since the cap went on. A very small amount of surface dispersant has been used since then.” The cap went on the well on July 15th.

This revelation should no doubt please Drs. Sylvia Earle, David Gallo, Susan Shaw, David Guggenheim and the countless other marine scientists and advocates who have been asking the Obama administration to order BP to halt its use of dispersants in the Gulf – issuing a ‘consensus statement’ urging a halt to any further use of dispersants in the Gulf.

It remains critical that the scientists and advocates continue to monitor the dispersant situation – while BP has drastically reduced dispersant use this past week, the oil giant could ramp it back up at any time.

gushing oil, chemical dispersants and sealife

Video released by the Deepwater Horizon Response team from the oil leak site shows the sheer volume of crude spraying into the deep sea 24/7 (visible especially starting at 1:58)

And we got word from the EPA yesterday that it has approved further use of chemical dispersants, both on the surface and underwater, even though EPA notes

“The effects of underwater dispersant use on the environment are still widely unknown, which is why we are testing to determine its effectiveness first and foremost. If it is determined that the use of this dispersant underwater is effective and that BP may continue its use, the Federal government will require regular analysis of its impact on the environment, water and air quality, and human health. We reserve the right to discontinue the use of this dispersant method if any negative impacts on the environment outweigh the benefits.”

Testing on a grand scale and then deciding over time if the negative impacts might outweigh the benefits? Of course, the relatively slow pace of scientific research means the determination of negative impacts will lag far behind any immediate ‘benefits’ of the chemicals breaking up oil slicks.

Countless known and little-known sea creatures in the waters of the Mississippi Canyon and beyond are being inundated with the gushing oil. Adding a brew of mystery chemicals to the mix is irresponsible at best – our government can do much better by us and by our environment than sanction wild and desperate use of untested chemicals.

Among the many creatures in the Gulf’s deep waters? Bioluminescent sea creatures like jellyfish – scientists have been working for years to unlock the secrets of this phenomenon.
