Blue Green Algae Information Eagle Creek Reservoir
The Marion County Health Department wants those using Eagle Creek Reservoir to be aware of the presence of blue-green algae cells. Test results from the week of August 13th 2007 reported an elevated count of blue-green algae cells in the reservoir. Local officials are awaiting further test results to determine how much toxin associated with the algae is present in the water.
The algae’s presence has prompted the health department, in consultation with the Indiana State Department of Health and Veolia Water, to advise those using the reservoir to avoid swallowing untreated reservoir water and to avoid prolonged contact with the water.
Veolia water performs routine sampling of the drinking water reservoirs monitoring for the organisms that produce taste and odor compounds. Veolia uses this information to decide if they need to treat the water to reduce the taste and odor-producing organisms. These organisms are different than those producing the toxin.
Health and water company officials say the algae’s presence does not impact the safety of water taken from the reservoir, treated and used to supplement the local drinking water supply.
Persons who choose to enter the water run the risk of skin irritation and rashes. Swimmers should understand and follow these precautions:
· Do not swallow or drink the untreated water from Eagle Creek Reservoir
· Avoid swimming in blue green algae scum or mats
· Wash as soon as possible after swimming, especially under swimming suits where the algae reactions are most severe.

Reports of convulsions, liver damage and death have been reported when exposed to very high levels and/or prolonged exposure to the toxins produced by blue-green algae.
