Bradenton - ASR Program
Basin Board at it's April meeting and the City has thus withdrawn their FY2007 cooperative funding application. The
District and City have executed the contract for this additional testing. Since that time the FDEP has changed their
position on permitting ASR facilities with the arsenic issue and is now indicating that any site with arsenic anywhere that
exceeds the DWS would not be permitted for operational use. The only option at this time is to explore pre-treatment of
the injection water to produce compatible water qualities between the injectant and the native water in the aquifer.
Recognizing this requirement, the District approached the City with a request to participate in a pre-treatment study to
remove dissolved oxygen and other oxidants from the injection water which are suspected of being the primary causes of
the arsenic mobilization. The property line monitoring well(s) will still be necessary, but it is contingent on the
implementation of the pre-treatment option. The scope of work for the pre-treatment option has been developed by the
City and bids have been awarded for construction under a separate contract. The City has completed construction of the
pre-treatment system and started cycle testing with de-oxygenated water on December 2, 2008. Equipment problem
arose after two weeks of operation and was shut down for repair in January. Repairs have been completed and the full
scale cycle test injecting 140 mg of de-oxygenated water began in August 2009.
