What does Activated Carbon Remove other than chemicals
Odor and taste
What type of filter did we create?
A charcoal (carbon) water filter

Non-point-source pollution
Although the earth is covered with water, what percentage of water is not salt water?
3%
What does the activated carbon remove?
Chemicals, toxins and odors from the water.
What continent has the worst access to clean water and sanitation?

What helps the water move through our filter?
Gravity!
This human activity, which includes the removal of trees and vegetation, contributes to increased runoff and less groundwater replenishment, worsening water pollution and shortages.
Deforestation
This is the name of the action people take to clean dirty water, often using materials like sand, charcoal, and gravel.
