Distinguish between renewable and nonrenewable groundwater resources. What are the consequences of overdrawing these two kinds of groundwater?
What will be an ideal response?
A nonrenewable groundwater resource is one "with a recharge rate of centuries or more." A renewable groundwater resource "is replenished by the percolation of precipitation water, so it is vulnerable to variations in precipitation."
The consequences of overdrawing groundwater include falling water tables, less surface water (e.g., wetlands, seeps, and springs dry up when water tables fall, thus decreasing water to streams), land subsidence, and saltwater intrusion.
