Today, the issue is not only
protecting water sources, but also finding & permitting them.

Aquifer Recharge & Recovery Well
SI was funded to research and develop the Aquifer
Recharge and Recovery Project (ARRP). The basic idea is to take existing
features on mined phosphate lands such as clay settling areas and tailing sand
deposits to naturally treat industrial wastewater and domestic effluent to meet
the stringent water quality criteria for recharge to the underlying
aquifer. The realistic practicality of this concept has been proven by the
results of a three-year pilot study designed, built and operated by SI.
Project 1) Aquifer Recharge & Recovery Well
SI was contracted to provide professional services related to the
design, permitting and implementation of an aquifer recharge and
recovery (ARRP) system to provide make-up water for fresh-water cooling towers
at a power generating station in Polk County, Florida. The power plant is located within in the Southwest Florida
Water Management Districtís Southern Water Use Caution Area where
groundwater resources are and will become critical in the future. The aquifer recharge and recovery concept is to inject water
into the groundwater aquifer and recover a percentage of the injected
water from a production well down gradient.
The percentage of injected water not recovered from the aquifer
is a net gain of a groundwater resource for the region.
SI obtained a
permit and constructed one Class V Group 8 exploratory well in order to
obtain information to determine the feasibility of injection for the
purpose of aquifer recharge. Upon
completion of lithologic, hydrogeologic, and water quality analyses, SI
concluded that the exploratory well is suitable for injection.
SI is currently working with the client and regulatory agencies
to obtain a permit for the test injection phase of the project.
In addition to the test injection well installation and testing, SI is
currently performing design, permitting, installation, testing and
sampling of two power plant water supply production wells to be used for
the recovery portion of the system.
Project 2) ARRP at a Phosphate
Mine in Hardee County (FL)
|SI was contracted in
2003 to develop an ARRP project for a phosphate mining company in
Florida. The idea of using excess surface water collected at the
mine during high rainfall periods for recharge to the underlying
Floridan Aquifer appealed to the County Commissioners. Initially,
a recharge rate of 2 MGD is considered to be expanded to 4MGD. The
project is in final design and permitting stages.
