a. Wyoming

b. Pennsylvania

c. Texas

d. California

e. Colorado

2. Before 2008 Oklahoma averaged 1.5 earthquakes per year. Now they are experiencing 2.5 earthquakes PER DAY! This dramatic increase is due to injecting hydraulic fracturing production water into the subsurface.

Select one:

True

False

3. At the beginning of the film, President Obama stated the U.S. had 100 years worth of natural gas supplies. That estimate was incorrect. What is the new estimate?

Select one:

a. 0-10 years

b. 10-20 years

Select one:

True

False

5. Some of the fracking wastewater is reused in California. What is that wastewater used for?

Select one:

a. Habitat restoration

b. Hydroelectric power production

c. Irrigation

d. Thermoelectric power production

e. Drinking water

Explanation / Answer

1. a. Wyoming.

b. Pennsylvania.

e. Colorado.

Reason : Studies have revealed that the contamination of drinking water was a result of fracking operation in Wyoming, Pennsylvania and Colorado. The contamination even includes the migration of methane into some people's drinking water.

2. True.

Reason : Oil production in Oklahoma has more than doubled in the past five years and in oilfields where there is a lot of production, the water is re-injected into the subsurface that in turn trigger earthquakes.

3. d) 80-90 years.

Reason : It has been estimated that there is about 1898 tcf of recoverable natural gas resources inthe U.S. and the nation's gas producers, on an average, pump out 23 tcf of gas per year. Thus, dividing 1898 by 23 we get 82.5 years of supply approximately.

4. False.

Reason : California is the fourth largest oil and gas producing state in the U.S while Texas ranks the first.

5. c) Irrigation.

Reason : In California, wastewater from fracking is used for irrigation purposes in the local districts.
