The BP oil spill was a tragedy. Eleven people died and untold damage was done to the environment.
But investing is a cold-hearted endeavor, and as the response to the spill evolved, investors tried to find ways to profit from it.
Early last May, we reported that a majority of the chemical dispersant used to break up the oil was coming from a little-known company called Nalco.
On May 3, the stock popped about 11 percent, and it was discussed as an interesting secondary play on the spill. One year later, the stock hasn't budged from that May 3 pop, and now the company is dealing with both a perception and a legal problem.
The perception nationally is that the dispersant is contributing to some of the problems with the Gulf's ecosystem. Some say it might be more harmful than the oil.
"What I am worried about down the line is the dispersant and the oil," said shrimper Glenn Poche. "We are worried about the reproduction of our seafood."
