# Aquitardifer: A New Hydrogeologic Term for Geologic Materials with both Aquitard and Aquifer Properties

## TL;DR

The paper introduces 'aquitardifer' as a new term for geologic materials that act as both aquifers and aquitards.

## Contribution

The novelty is the introduction of a new hydrogeologic term to describe materials with dual aquifer and aquitard properties.

## Key findings

- The term 'aquitardifer' is proposed to describe geologic materials with both aquitard and aquifer properties.
- Examples and justification for the term's use in hydrogeology are provided.

## Abstract

We propose that a new term, aquitardifer, be added to the hydrogeologic nomenclature. Aquitardifer, a blend of the terms aquitard and aquifer, accounts for geologic materials that have properties of both as traditionally defined. Several examples of aquitardifers are provided, as is justification for and applicability of the term.
