The state regulatory agency finds the industry out of compliance because the minimum dissolved oxygen violates state standards, and wants to impose a fine. A wastewater treatment plant is too expensive, so the industry looks around for another solution. A salesman suggests that a special kind of freeze-dried bacteria, particularly adapted to the plant's organic waste, be dumped into the river at the point of discharge: the freeze-dried bacteria will come to life, break down the organic material, and solve the problem. Will this approach work? Why or why not? Draw the dissolved
