Emerald Coast ChapterWe are the beach people. The surfers, paddle boarders, kayakers, fishermen, swimmers, beach runners, and walkers. We are activists who want to protect the ocean environment, and our access to it! The ocean and beaches are our playground! More Details

Data Report -Sample Collection Date: 08/12/10
All samples tested below the detection limit (ND) for every parameter with the exception of the below data:
|Sample ID||Collected Date||Parameter||Results||Units||RL|
|Blue Mountain Beach||8/12/10||Acenaphthylene||0.047||ppb||0.045|
|Blue Mountain Beach||8/12/10||C2-Fluorenes||0.053||ppb||0.045|
|Okaloosa Island Pier||8/12/10||Acenaphthylene||0.045||ppb||0.041|
|Panama City, Pier Park||8/12/10||Acenaphthylene||0.040||ppb||0.040|
ppb = parts per billion
RL = Recording Limit
The positive results for Acenaphthylene are most likely due to lab contamination and may not indicate that this compound was in the original water sample, as the quality control also showed low levels of Acenaphthylene.
There was an extremely small amount of C2-Flourene detected, 0.053 ppb, in the Blue Mountain Beach sample. This amount is just barely above the reporting limit, and lies well below the Flourene criteria set by EPA for ecosystem effects in marine waters (30 ppb). Unfortunately, there is no human health standard set for this compound in marine waters. The low level of C2-Flourene detected in the Blue Mountain Beach sample does not really rise above background levels and could be attributed to boat diesel or street run-off.
These initial results do not mean all of the tested beaches are safe for human exposure. Testing for oil and dispersant compounds is difficult, as they are not evenly distributed in the water and are generally present only in very sparse (parts per billion) yet potentially toxic amounts. It also takes nearly two weeks before our data is available, so any oil or dispersants could have moved in or out of the tested beaches during that time.
We are hoping to continue this testing as long as our funding allows so that we can provide better, long term information regarding which beaches in our area remain adversely affected by the Deepwater Horizon oil disaster.
