What type of waste products may be discharged into u. s. waters?

None.

Explanation:

Disposal of waste products in waterways is done by people who, in general, ignore its negative impact on the environment. Waste products accumulates on the banks or at the bottom of rivers and other sources. When it rains, they hinder or impede the flow of water, causing floods and eventually tragedies. In addition, they can be ingested by animals.

When they arrive at sea, the waste products is carried to every corner of the planet, interfering negatively in marine life. This also causes them to accumulate on different surfaces, such as corals, ice, islands or the bottom of the oceans. Fish, turtles, birds and all marine fauna can be seriously hit by the waste and contaminated by toxic substances.

For this reason, a ban on the unloading of any type of waste products in US waters has been established. That is, no type of waste products can be discharged into US waters.
