Draw the graphs for the markets for the chemical industry and the bottled water industry. Assume the chemical companies operate upstream of a river, while the bottled water companies operate downstream. Also assume the neither industry initially pollutes. Now suppose that the chemical industry decides that it is cheaper to dump their waste into the river, rather than treat it to avoid pollution. As a result of this decision, what happens to the price and quantity of bottled water produced? What happens to the price of goods sold in the chemical industry?
