You have arrived on the scene of an overturned gasoline tanker. Gasoline is leaking over an
embankment and into a nearby creek. What would be an efficient means of reducing the effects of
gasoline in the waterway?
A. Install spill booms downstream to absorb gasoline as it floats across the top of the water.
B. Build an underflow dam so that the heavier gasoline particles can sink and fresh water can flow
through the dam.
