Groundwater Depletion and Land Subsidence
Clarifies how excessive groundwater pumping can compact aquifer sediments, cause land subsidence, and damage infrastructure.

Aquifer Recharge Concepts
A collection of practical guides that explain aquifer recharge, groundwater planning, drought resilience, and long-term water supply decisions.
Aquifer Recharge Explainers
This collection explains aquifer recharge concepts that are often important in policy and planning discussions, including what aquifers are, how groundwater recharge works, how managed aquifer recharge stores water underground, why geology and water quality matter, and how governance shapes long-term project success.
Use these guides to support briefings, groundwater planning, drought-resilience discussions, stormwater and land-use decisions, infrastructure planning, and clearer communication about managed aquifer recharge.

How Geology Determines Whether MAR Will Work
Walks through why managed aquifer recharge depends on aquifer suitability, permeability, confinement, faults, and recovery potential.
How Groundwater Recharge Works
Discusses how water moves from the surface into groundwater and why only some precipitation or surface water becomes aquifer recharge.
How MAR Connects Water Supply, Flood Protection, and Land-Use Planning
Explains why managed aquifer recharge depends on coordinated planning across water supply, flood management, land use, stormwater systems, infrastructure, and groundwater governance.
Managed Aquifer Recharge in Practice: California Examples
Shows how four California managed aquifer recharge examples address different water-management problems.
Recharge and Saltwater Intrusion
Shows how groundwater pumping near the coast can allow saltwater to enter freshwater aquifers, and how recharge can help protect coastal groundwater supplies.
Surface Recharge vs. Injection Wells
Compares surface recharge and injection wells as two managed aquifer recharge approaches.
What an Aquifer Actually Is
Explains what aquifers are, how they store groundwater, and why geology determines whether underground water storage is possible.
What Managed Aquifer Recharge Means
Explores how managed aquifer recharge depends on suitable geology, source water, infrastructure, monitoring, and governance.
What Water Banking Means
Discusses water banking as storing water underground and managing deposits, withdrawals, ownership, recovery rights, and operating limits.
Where Recharge Water Comes From
Breaks down common water sources for managed aquifer recharge and the tradeoffs associated with river water, stormwater, and treated wastewater.
Why Aquifer Storage Can Help with Drought
Explores how managed aquifer recharge can support drought resilience by storing water underground when it is available and recovering it during dry periods.
Why Governance Matters as Much as Geology
Discusses why managed aquifer recharge success depends on suitable geology as well as regulation, management, funding, monitoring, water rights, and public trust.
Why Recharge Is Also Stormwater Policy
Describes how stormwater management and managed aquifer recharge can overlap when runoff is captured, treated, and directed into suitable aquifers.
Why Water Quality Monitoring Is Central to Recharge Projects
Explains why managed aquifer recharge projects need source-water assessment, treatment where needed, groundwater monitoring, and public communication.
