225 wells provided water-level and pressure measurements to construct a map of the Upper Floridan aquifer's potentiometric surface for September 2000. The dataset, summarized by the USGS, represents the altitude of water in tightly cased wells. It documents a historical cone of depression in the Jesup, Wayne County area due to industrial pumping of approximately 63.9 million gallons per day.
Use Cases
- Model groundwater flow direction and gradient using the mapped potentiometric surface contours.
- Analyze the impact of industrial pumping, specifically the 63.9 Mgal/d withdrawal, on the cone of depression in the Jesup area.
- Compare water-level altitudes from the 225 measurement wells to historical maps for change detection.
- Estimate aquifer productivity and recharge rates based on the potentiometric surface configuration for September 2000.
Strengths
- Data from 225 individual well measurements provides a detailed spatial snapshot.
- Specific temporal focus on September 2000 allows for seasonal analysis.
Limitations
- Single temporal snapshot (September 2000) limits analysis of trends or seasonal variability.
- Spatial coverage is limited to the coastal area of Georgia, not the full Floridan aquifer system.
