As wastes are added to water, why does the pH levels drop (becoming more acidic)?

As bacteria feeding on the wastes increase, they take in O2 which causes more O2 to be available to bond with the decreased H+ ions.

As bacteria feeding on the wastes increases their CO2 output; it reduces the pH.

The “trash fish” releases ammonia into the water increasing the pH.

Dissolved oxygen and carbon dioxide has no affect on a river’s pH.

Oxygen-depleted (hypoxia) zones of the oceans, such as the one at the mouth of the Mississippi River, are most likely caused by

large numbers of fish that are using up all the oxygen in the water

a reduction in the plant life in rivers that empty into the ocean near the dead zone

Why does the DO bottom out at D?

D is where the waste entered the river

It’s a natural occurrence since the nutrients in a river fluctuates every mile

Bacteria feeding on the bacteria was putting O3 back into the water

Bacteria feeding on the wastes used up the oxygen in the water

So that recovery could start at E
