Multiple Choice

Read the following scenario and answer the question below.
On a September day in 1999, folks began to notice that Lake Jackson in the panhandle region of northern Florida was shrinking. Within a few days, it was almost gone. A sinkhole had opened beneath the lake and drained it, along with all of the fish and alligators.
As aquifers lose water, their substrates can become weaker and less capable of supporting overlying strata and any human structures built upon them. In such cases, the land surface above may subside. Sometimes subsidence can occur locally and suddenly, in the form of sinkholes, areas where the ground gives way with little warning. Once the ground subsides, soil becomes compacted, losing the porosity that enabled it to hold water. Recharging a depleted aquifer may therefore become more difficult.
-One reasonable way to prevent sinkholes might be to ________________.

• A) pump sand and gravel into the aquifer to fill in the bottom levels, thus raising the water table
• B) install supports to maintain the shape of the underground aquifer
• C) pump wastewater and sewage directly into the aquifer to maintain the water table
• D) increase groundwater recharge by constructing artificial wetlands that use treated municipal wastewater
• E) have the local water company regularly transfer water from one local aquifer to the next, maintaining the average water level
