Groundwater Assessment Program Research Projects

The Groundwater Assessment Program conducts groundwater and surface water-related research projects. In addition to these ongoing research projects, the Groundwater Assessment Program maintains a real-time system that monitors water levels in wells and springs in Alabama.

Statewide Groundwater Assessment

The Groundwater Assessment Program division of the Geological Survey of Alabama, in conjunction with the Alabama Department of Economic and Community Affairs Office of Water Resources (OWR) is conducting a comprehensive statewide water assessment. Both the groundwater and surface water assessments were mandated as part of an initiative by Governor Robert Bentley and the Permanent Joint Legislative Committee on Water Policy and Management in an effort to develop a statewide water resource management plan and future water policy legislation.

The groundwater assessment includes data concerning stratigraphy, hydrogeological characteristics, current groundwater development and future groundwater development potential, production impacts, and groundwater availability and recharge, which will provide comprehensive knowledge of groundwater resources, which in turn will provide a foundation in support of future water management and policy decisions.

The initial groundwater assessment began in southeast Alabama and has been published as Open File Report 1406. Alabama Water Resource Assessment: Groundwater availability in Southeast Alabama: Scientific Data for Water Resource Development, Protection, Policy, and Management; A Demonstration Assessment for Gov. Robert Bentley and the Permanent Joint Legislative Committee on Water Policy and Management.

 

Research is currently being conducted throughout the state to complete the statewide assessment.


Real-Time Monitoring Program

The Real-Time Monitoring Program monitors groundwater conditions throughout the state. Currently the program is comprised of 24 wells and 2 springs, located at varying depths in both semi-confined and confined aquifers.

The monitoring systems are equipped with automatic digital recording equipment and a telemetry interface system, which transmits data by cellular signal directly to the GAP office, where it is uploaded graphically to the GAP website daily.

Long-term hydrographs from monitoring wells provide an indicator of water level fluctuations affected by groundwater withdrawals, land use, and climatic changes. The period of record for some of the wells continuously monitored by the GSA is longer than 60 years, providing excellent data trend analysis. The response of groundwater levels to meteorological drought is generally slower than other drought indicators, such as soil moisture and stream flow, and can provide information related to drought intensity and duration. Percentiles are included with the real-time hydrographs to allow comparison of recent water levels with levels collected during the period of record.

Periodic Monitoring Program

Periodic Monitoring WellThe GAP monitors groundwater levels in 369 water wells and discharges for 49 springs throughout the state. The wells are both publicly and privately owned and have a variety of purposes including unused, public, industrial, private water supply, stock, and irrigation. Some of the records in this program are older than 30 years and reflect the changing climatic conditions and water use patterns in the state.


Public Water Supply Systems

Water TankThe Groundwater Assessment Program actively provides assistance and information to public water supply systems. Assistance includes new source development and protection of water sources.
