Pelican Bay Services Division Water Management Committee Meeting
June 30, 2016
AGENDA APPROVAL
Dr. Trecker motioned, Mr. Cravens seconded to approve the agenda as amended
with the addition of a discussion item "Sediment testing data" as item #7.1 and
agenda item #8 was amended to "nutrient removal" from "phosphate removal."
The motion carried unanimously.
APPROVAL OF 05/10/16 MEETING MINUTES
Dr. Trecker motioned, Mr. Cravens seconded to approve the 05/10/16 meeting
minutes as presented. The motion carried unanimously.
AUDIENCE COMMENTS
Mr. Ray O'Keefe commented on alum and bacteria treatments being tested for algae and
phosphate removal in the three lakes at the Breakwater.
STATUS OF AERATOR PURCHASE
Mr. Bolick reported that the approval for the purchase of eight solar aeration systems is
included on the July 12 BCC agenda; Aquagenics was the low bidder at $82,498. A separate
solicitation will be issued for installation. A document entitled, "Pelican Bay Lakes"was
distributed which identified the lakes which currently contain aerators as well as the eight lakes
selected for this project; the document was added to the record.
ALGAE TREATMENTS AND MEASURES OF EFFECTIVENESS
LAKES SELECTED FOR TREATMENT WITH BLUE TILAPIA
Mr. Cravens commented on the high effectiveness of blue tilapia to remove algae, and the
low survival rate of the blue tilapia in Pelican Bay lakes as a result of predators.
LAKES SELECTED FOR TREATMENT WITH PEROXIDE
Mr. Bolick commented on the system-wide use of peroxide in PBSD lakes.
LAKES SELECTED FOR TREATMENT WITH PEROXIDE AND BACTERIA
Mr. Bolick commented on his ongoing bacterial treatment in two lakes. He estimated
that he would need to study this treatment for at least a year to determine its effectiveness. By
consensus, the committee agreed to bacterial treatment in two additional lakes and that"before
and after"pictures were to be taken to properly assess the effectiveness of the bacteria.
ESTABLISH DATES TO BEGIN EFFECTIVENESS TESTING
Mr. Cravens discussed the need for better methods to measure and document the
effectiveness of each type of algae treatment. He recommended obtaining photographic data
("before and after"photos) for each type of treatment explored in order to draw accurate
conclusions on treatment effectiveness. In addition, Mr. Cravens recommended that the PBSD
examine the cost effectiveness of each type of treatment.
Mr. Bolick provided a document entitled, "PBSD Aquatic Spraying" which listed the
costs of different types of algae treatments; the document was added to the record.

Pelican Bay Services Division Water Management Committee Meeting
June 30,2016
By consensus, the committee agreed that the agenda for the 7/6/16 PBSD Board meeting
should include (1) approval of monitoring algae treatments of 10 PBSD lakes, and(2) approval
of bacterial treatment of two additional lakes.
Mr. Ray O'Keefe commented on a new process of lake algae removal utilizing floating
rakes and suction.
SEDIMENT TESTING DATA (ADD-ON)
Dr. Trecker received the sediment testing data for 10 lakes from Earth Tech and
concluded, (1) nearly all of the lake copper is in the sediment, (2) soluble copper levels in Clam
Bay remain low, and (3) sediment levels in most lakes tested are very low, except for lakes 2-9
and 2-12, which warrant future tracking. Documents on the sediment testing provided by Earth
Tech were distributed and added to the record.
NUTRIENT REMOVAL
Dr. Trecker reported on a new process developed by Green Technologies to remove
phosphate from lake water by pumping the lake water through a column of zirconium ions which
attach to the phosphate ions. He suggested revisiting this possible method of phosphate removal
after an estimate of cost is received from the company.
DISCUSSION OF BANNING FERTILIZER DURING THE RAINY SEASON
The committee discussed the ban of fertilizer from June 1 to October 1, as included in
landscaping best management practices (BMP). Dr. Trecker suggested sending a letter to all
Pelican Bay homeowners' associations to remind them of the BMP recommended fertilizer ban
during the rainy season.
