Why is only a small portion of Earth's freshwater available to drink?

• Most is polluted.
• Most is frozen.
• Most is too salty.
• Most is underground.

Increased nitrates (nitrogen fertilizer) in water will:

• decrease turbidity.

• increase algal bloom.

• increase D.O.

• increase pH.

What is the major difference between porosity and permeability?

• Permeability describes the amount of water a rock or sediment layer can hold, and porosity is the ability of the rock or sediment layer to allow water to pass through it.

• Its depth has the best potential for a good supply of water.

• Porosity describes the amount of water a rock or sediment layer can hold, and permeability is the ability of the rock or sediment layer to allow water to pass through it.

• Porosity describes groundwater and permeability describes underground oil and natural gas.

How would several wells in a given area affect the balance of groundwater recharge and discharge?

• The wells would provide dissolved oxygen.

• The wells would increase the water table level by adding water from runoff.

• The wells would deplete the groundwater which is usually supplied by percolation from rain.

• The wells would provide storage areas for groundwater to maintain the water level.
