Surface Water and Underground Water Practice Test

An unconfined aquifer is more likely to contain pathogens and pollutants.

There are few sources for an unconfined aquifer to recharge and it is very easy to pump out more water than what replenishes the table naturally.

An unconfined aquifer is usually further below ground and can be very expensive to drill into and pump water out of the well.

An unconfined aquifer can be exhausted faster than a confined aquifer.

Sulfur deposits (which taste horrible) are more common in unconfined aquifers.
