GRAYSON COUNTY, TX-- For seven months now, an Army Corps of Engineers warning has been in effect, advising lake goers to avoid contact with the water.
While, the Grayson County Health Department agrees that there's Blue Green Algae in the lake. They say toxicity levels aren't high enough to harm people.
"With the results we got in February, the public should be, should have literally no concern about blue green algae in the month of March of 2012," explained, Dr. John Teel, Director of the Grayson County Health Department.
Researchers with the Corps of Engineers say their findings are sound.And they plan to keep an advisory in place.
"We're still seeing blue green algae densities in certain areas that support an advisory level, based on the guidelines we use for the world health organization," Paul Balkenbush, Environmentalist for the Corps of Engineers, said.
The Corps and the Health Department are using the same samples taken on the lake.
Corps tests found zero traces of Blue Green Algae, in areas like Little Glasses Creek and higher levels in other area, like Treasure island.
But the health department says it found the toxin levels were similar throughout the lake, with the most toxic levels at 1/10th of 1 part per billion.
These are called trace levels and the health department claims they don't hurt you in any way.
"Nearly everything we consume, everything we breath, the air that I'm breathing now, there are ultra trace levels, for example, in the air there are gas levels and they are not harmful, not at those levels," Teel said.
Experts with both groups expect levels to change, as they're effected by both lake levels and temperature.
Each department plans to continue to test the water.
"We really are in a wait and see situation when it comes to seeing what's going to happen down the road," Balkenbush said.
