Environmental Hazards On the Bottom of the Gulf of Mexico

Now that it seems the explosion and the resulting gigantic oil spill from the Deepwater Horizon oil well of British Petroleum Corporation (BP) are under control, one would think that perhaps we could relax with the hopes that nothing like that would happen again. But due to the publicity and numerous investigations which have been conducted, lo, another worry raises it's head.
There are two sets of regulations for the sealing of abandoned wells. One is a temporary fix which is required if the well is planned to be reopened. To leave one in this condition, the company must supply their plans to reopen the well within a year or to permanently re-plug it.
There are presently about 3,500 wells which have been "temporarily abandoned" and about three-fourths of those have been abandoned for more than one year with some for more than fifty years. In fact, it is reported that more than 1,000 have been left more than a decade. An AP investigator called the gulf floor, "...an environmental minefield".
No one is sure how many, if any, of these wells are leaking crude into the gulf waters. The numbers are so staggering that to reseal all which are in the "temporary" category would now be cost prohibitive without sending petroleum products prices through the ceiling. For the states and/or federal governments to undertake it, would place tremendous strains on their budgets.
Not only is there a possibility that some wells will begin leaking, some have well pipes and other structures which come to within 12 feet of the gulf surface. In late July, a tug boat pushing a barge struck one oil well some 65 miles south of New Orleans, sending a geyser-like spout of gas and oil 100 feet high. Fortunately it was in only about 20 feet of water and a well-control company was able to reseal the well in a reasonable time.
Even small leaks and small accidents such as the tugboat above, all add to the hazards towards the gulf's ecosystem. More strenuous regulations need to be implemented, or at least our present ones need to be strictly enforced. BP was in the process of temporarily sealing off the Deepwater Horizon well when the explosion and fire occurred. Some rule or act had to have been bypassed or poorly followed to have caused the accident. With all the 27,000 abandoned wells, and never such a catastrophe before, there had to be a reason.
