I disagree. The scrap metal yard next to a river that discharges metals, solvents, and O&G into the river every time it rains and never even bothered to apply for a CWA discharge permit is not "doing what the consumer tells them to." They are violating federal law in the hopes that no one catches them and brings them to court. The scrap metal yard is not doing it "for us." It sits on tons of copper etc until volatile world spot market prices hit a high note and then unloads the scrap for a big profit. And there is a ton of similar industries.
The pisser is that there are some good industrial actors that take the time and spend the money to comply with the CWA, and those good actors are at a competitive disadvantage to the bad actors if no one prosecutes the bad actors. Thankfully, "any person" can sue a violator of the CWA (so long as that person or a group's members use and enjoy the receiving water).
