All water is recycled. If harmful chemicals go down the drain, they go into the streams and rivers and eventually through water treatment plants into city water supplies.
The water cycle shows that water continually evaporates, condenses, precipitates and runs off. The cheicals stay.

Not as bad as u think . If u put in HCL very bad acid . Then your neighbor dumps caustic sods very bad basic ,now what do u have. U check it and the PH 7 now what u have . Nothing but table salt and water. All the chemicals can be canceled out ,that is why the ocean's are salty.

Because they can corrode the plumbing, and they can mix with someone else's waste chemicals to create a dangerous substance tike poison or explosives.
