Groundwater modeling

Find information about the modeling work the District does and the models for observing groundwater flow.

Groundwater recharge

Read about how the underground aquifers that provide our drinking water are refilled, or recharged, and how that is tracked.

Groundwater monitoring networks

The District monitors a variety of wells throughout the District’s 18-county service area to determine changes in groundwater supplies.

Hydrogeologic Information System

Use this tool to explore the dynamics of the aquifer system by creating maps, charts and graphs based on a database of well information.

Groundwater resource assessment

The groundwater resource assessment program focuses on providing resource assessment and field services in support of District activities. Northeast Florida relies on groundwater to meet more than 90 percent of its water supply needs and long-term hydrologic information is required to assess the availability of this water supply source.

The resource assessment group performs detailed hydrologic assessments, designs and evaluates monitoring networks, and conducts interpretive investigations. The field services group constructs and maintains monitoring wells, oversees contractual drilling services, conducts aquifer performance tests and related hydrologic testing, and provides geophysical well logging services. This program directly supports the Bureau of Water Supply, the Bureau of Water Use Regulation, and the minimum flows and levels programs and other District programs. Taken as a whole, the subprojects in this program provide the scientific means to evaluate groundwater resources, identify long-term trends, detect potential problem areas, and gauge the effectiveness of management strategies.
