-Runoff

-pH.

These are all factors That affect the quality of water.

What is pH??

pH stands for potential hydrogen the "p" stand for potential and the "H" stand for hydrogen. A pH scale is a scale used to rank the acidity of substances to other substances.

Runoff

Toxic runoff can pollute surface waters like rivers and lakes, as well as seep into underground ground supplies.

Runoff??

Thermal Pollution!!!!

Thermal Pollution is when the temperature of the water is changed by Humans. As a result of this the natural filters of water (Fish) can die which can make are water dirty and undrinkable. Warm water has less oxygen and that hurts the organisms that live in the water.

How much water on earth is actually drinkable??

70% of our Earth is made up of water even then only 2.5% is fresh and less than 1% of that 2.5% is already drinkable and ready to go to drink the rest of that fresh water is either Groundwater, Glaciers, or ice packs.
