One area state park is taken off the Toxin Advisory list while another is downgraded.
The Ohio EPA removed the Toxin Advisory at Burr Oak State Park after two weeks of testing. Officials indicate the samples taken came back without traces of any of the four major toxins detected previously.
Meanwhile, the No Contact Advisory at Blue Rock State Park was downgraded to a Toxin Advisory. Two previous toxins were not found in samples collected over the past two weeks, and there were lower samples of anatoxin-a along with trace amounts of microcystin. Officials say they are now encouraging visitors to boat again on the water, but they still ask that people avoid direct contact with the water.
The Ohio EPA began issuing Toxin Advisories across the state back in August after an unidentified blue-green algae began forming on inland state park lakes.
