14 October 2010 NEW ORLEANS — Dead birds are wrapped in foil or paper, then sealed in plastic bags to avoid cross contamination. Dolphin tissue samples and dead sea turtles are kept in locked freezers. Field notebooks are collected and secured. Scientists examining dead animals that were discovered along the Gulf Coast in the wake of the BP oil spill are observing strict laboratory protocols, knowing everything they touch could become evidence in what may prove to be the biggest environmental case in U.S. history. Like detectives on a murder case, government scientists — and outside experts under contract to the government — are using CSI-style techniques to determine whether the oil is to blame for the wildlife deaths. The U.S. Justice Department is investigating whether those responsible for the spill violated environmental laws that carry civil and sometimes criminal penalties, and the scientists are taking extraordinary steps to make sure their findings hold up in court. “What we want to do is to make sure that the findings and the results we get aren’t called into question in court based on chain of custody or other legal issues,” said Dr. Michael Ziccardi, a veterinarian. “We’re treating oiled wildlife response like a crime scene.” Attorney General Eric Holder said in June that the government will prosecute violations of such laws as the Clean Water Act, the Migratory Bird Treaty Act and the Endangered Species Act. The number of dead creatures will help determine the fines and penalties levied against BP and other companies involved. …
