Water Quality Update – October 9, 2015

Very few samples were collected and analyzed this week. Samples were collected from Floridatown, Blackwater River (@ Milton), and Bayou Texar only. Salinities seemed a bit high at both Floridatown and Bayou Texar. Dissolved oxygens are fine. Bacteria levels are fine.

 

High levels of Karenia brevis (red tide) were reported along shore and offshore of Bay and Gulf counties (Panama City and Port St. Joe). High levels were also reported for Manatee, Sarasota, and northern Charlotte counties. Background levels of red tide were detected offshore of Franklin County in the panhandle, Levy County in the big bend, and Lee County in SW Florida. Red tide was sampled for in Escambia County but was not found. It was not sampled for in Santa Rosa County this week. The FWC fish kill database is still down and so we are not aware of any fish kills in the area at this time

 

UWF will survey for lionfish inshore this weekend. Will report next week.

 

There has been concern about cases of Vibrio infection. We have posted an article about this bacteria which you can find at http://escambia.ifas.ufl.edu/blog/2015/07/10/what-you-need-to-know-about-vibrio-bacteria-in-gulf-waters/

 

Health Advisories – 4 reported for October

Fish Kills – none for October

Red Tide – none for October

Inshore Lionfish – none for October

 

Here are the numbers…

HIGH SCHOOL DATA – FOR SEPTEMBER                                                               

Washington High sampled Texar on Sep 1 and 15.

Water temperatures declined over those two weeks

Salinities were between 10 – 20 ppt

Dissolved oxygen read 3.8 mg/L at station #1 (12th avenue bridge) on Sep 1 but increased

Station #1 had high nitrogen levels all month (1400 – 1800 µg/L)

Stations #3, #4 (near Bayview Park) were 0 µg/L

There was a significant increase in phosphorus at #3 (Oyster Barn boat ramp) on Sep 1

There was a significant increase in chlorophyll a at #2 (Hyde Park road)

There was a significant decrease in water clarity in the bayou during September

 

West Florida sampled Upper Perdido Bay between Jan-Apr 2015 – no report so far this semester

Saw a significant decrease in total nitrogen in the spring

Saw a significant decrease in total phosphorus in the spring

Chlorophyll a was much higher in Jan than anytime during the spring

 

Escambia High – no report at this time

 

ENT – Enterococcus bacteria; an individual sample should not be more than 104 colonies / 100ml

Fecal Coliform – an individual sample should not be more than 800 colonies / 100ml of sample

DO  – dissolved oxygen should be 3.0 mg/L or higher

ECHD – Escambia County Health Department  (Enterococcus bacteria)

Good               0 – 35 colonies / 100ml

Moderate        36 – 104 colonies / 100ml

Poor                +104 colonies / 100ml
