CONTENT SAMPLE:

A boom that is well-placed and doing its job can hold back and collect huge amounts of
oil in a thick pool, so long as the water is calm and the weather cooperates. This boom was
placed by a bridge across an inlet, making it accessible to a tank truck. The truck, owned by a
firm that specializes in cleaning up oil spills, is pumping up the trapped oil. Eventually much of
the oil will be salvaged.
