The people in charge of making sure water companies don't pollute our lakes and oceans now have to think about making those companies earn more money too.
Some people worry that this means the water companies won't have to pay as much for polluting.
The government says doing this will help the whole country make more money, but other people say we need to protect the environment too.
Some companies that take care of our water are already having a hard time making enough money, and this could make it worse.
