QUESTION 12

1. Safe yield is the amount of natural recharge to the aquifer.

   True

   False

2. Gasoline has lower vapor pressure than water at room temperature.

   True

   False

3. Injection of surface water to aquifer can decrease safe yield of the aquifer.

   True

   False

4. Groundwater replenishment system in Orange County, CA uses microfiltration, reverse osmosis, and UV light/hydrogen peroxide to treat fresh water brought from the Colorado River. The treated water is then injected into an aquifer via injection wells.

   True

   False

5. When water vapor (clouds) rise over high mountains, precipitation can occur because vapor pressure increases.

   True

   False

6. Wet soils warm up faster than drier soils in the sun because water has higher heat conductivity than air.

   True

   False

Answer 1

12.

Safe yield is the amount of groundwater that can safely be withdrawn. So the statement is false.

The vapour pressure of water is much lower than gasoline at room temperature. So the statement is false.

Safe yield increases with water injection. So the statement is false.

The water is not treated to that extent before injection. So the statement is false.
