Why Do Cities Have To Test For PAHs?

Cities must test for PAHs before they dredge their ponds, and there are thousands of ponds. Also, starting in around 2023, cities will be required to perform work to restore the water quality function of their ponds. Again, the cost of complying with these regulations will be higher because of the presence of PAHs in the sediment from coal tar sealant runoff.
