The Village of Third Lake is having ongoing testing for an algae bloom that has appeared on Third Lake in late summer. The conditions are constantly changing and test results take days to get back. On September 22nd, the results of the test were 900 parts per billion (ppb) of the toxin. The results of the test on September 28th were 5.16 ppb. This week’s test (October 5th) results were at 31.8 ppb of the toxin. This is still above the limit of 8 ppb that IEPA recommends as safe.
The Illinois Department of Public Health (IDPH) warns that it is impossible to tell from a visual inspection whether an algal bloom is toxic, therefore you should avoid the water where the bloom is located. The toxins in an algae bloom can cause a variety of symptoms by affecting the skin, liver, GI tract, and nervous system. Ingestion, inhalation, or direct contact with contaminated water may cause illness.
The IDPH warns that children and pets stay out of the water. Do not allow pets to drink from the water and do not allow them to lick their fur after swimming in water containing a blue-green algae bloom. If you or your pet has contact with water you suspect may have a blue-green algae bloom, rinse off with clean, fresh water as soon as possible.
We have added Druce Lake to our testing sites but have not received any data yet. The Village of Third Lake will continue monitoring the algae bloom situation and keep residents posted on the results.
