Quote of the Day - Fish is the only food that is considered spoiled once it smells like what it is.
You would hardly know it looking off the coast. But, what settled to the sea floor has now moved up the food chain. And perhaps most important, it has gotten into the fish, which we eat.
The government is in the process of cleaning it up. Rather than remove the DDT, however, the plan is to cap it and leave it in place.
Perhaps they're making progress. You can see the sea floor the way it was, with part of the cap in place (that red line is a worm), and also part way. This pilot project covered only about 1% of the affected area, and took over 100 barge loads of sand.
I thought that sand moved around pretty quickly on the ocean floor, but then again, I'm only a scuba diver, not a scientist. What do I know?
