Quizplus · Accepted Answer

An aquifer needs to be porous (allow water to flow through) and permeable (allow water to infiltrate). Uncemented sand that is loosely compacted meets both of these criteria, allowing for easy movement and storage of groundwater. Cemented sand or gravel, even if loosely compacted, restricts the movement and storage of groundwater. Uncemented, loosely compacted clay is not very porous or permeable, and is more likely to act as an aquitard (a layer that restricts or prevents the flow of groundwater) rather than an aquifer.
