Water Notes Pages: 12 – 20 Water Quality Book
2
Groundwater Groundwater is stored underground It may be very young or very old water (put there recently or a long time ago) Aquifer: “Porous” rock that can hold water Porous: has tiny holes
3
Groundwater is finite: Limited Groundwater flows underground and can move quickly or slowly. (Inches per year – feet per day) When water falls on the surface of the earth it can seep into the ground. If the soil is polluted, then the groundwater will be polluted.
4
Acid Rain pH Scale: 1……Acids…….7…….Bases………14 Acids: Less than pH of 7 taste sour can dissolve metals pH less than 7 Neutral: 7 Bases: Greater than a pH of 7 taste bitter feel slippery pH greater than 7
5
Buffer A substance that will neutralize an acid or a base. Neutralization: When acids and bases cancel each other out. (make them a pH of 7 - Neutral) Acid Rain: pH less than 5.6 Can come from Car exhaust – Coal burning Factories
6
Strength of an Acid or Base Every time you move one number on the pH scale, it changes the strength of the acid or base by 10X. 7 8 9 10 10X 10X 10X
7
Dams Uses for Dams River travel – barges Electricity Dams can be harmful: *Impounded water: floods the land *Increases water temp.(harms fish) Anadramous Fish: fish need to swim upstream to lay eggs Fish can not get over the Dams. (Use Fish Ladders)
