What is an aquifer?

An aquifer is a layer of rock, sand, gravel, or sediment that has enough connected pores, cracks, or spaces to store and transmit groundwater.[1]
From a natural perspective, aquifers are imperative to maintaining life. Groundwater-dependent ecosystems are ecosystems that are supported by groundwater.
These places include springs and seeps, caves and karst systems, and deep-rooted plant communities (phreatophytes). In many cases, rivers, wetlands, and lakes are also included. Where groundwater meets the surface, a unique community of plants and animals flourish. A wide variety of rare, threatened, and endangered species call these places home.[2]
How Do Humans Use Aquifers?
While the natural world relies on aquifers to flourish, human civilization similarly depends on the constant replenishment of these underground stores.
Much of the water we use for domestic, industrial, or agricultural purposes is groundwater. Most groundwater, including a significant amount of our drinking water, comes from aquifers. In order to access this water, a well must be created by drilling a hole that reaches the aquifer.[3]
As the most densely populated state, New Jersey faces unique problems with maintaining a healthy aquifer level while simultaneously supporting the population.
Why Is This A Problem?
Groundwater can become depleted if we use it at a faster rate than it can replenish itself. The replenishment of aquifers by precipitation is called recharging. Depletion of aquifers has increased primarily due to expanding agricultural irrigation.[3]
On top of overuse, climate change has had negative effects on aquifer levels, as well. More frequent and intense climate extremes (droughts and floods) increase variability in precipitation, soil moisture and surface water.[4]
As more natural lands that absorb rainfall are paved over for roads and parking lots, excess water from heavier storms runs into storm drains before it can be absorbed into the ground to replenish the aquifers that are critical to drinking water.[5]
Design a solution to the problem, based on science: There are several ways in which students can design solutions to tackle aquifers in New Jersey
Mitigation of current low levels
This finding ways to stop the further draining of aquifers and increasing the refill rate.
Planning for the future
This involves proposing ways to avoid this becoming an issue again in future years.
Alerting the public
This involves creating an information campaign to alert the public of the issue and what is being done to address it.
