What:    Blue-Green Algal Blooms and Nutrients that Cause Them: Exploring Indiana’s Story

When:    June 17, 2010, 8:00am-5:00pm

Where:    The Rathskeller Restaurant, 401 E. Michigan Street, Indianapolis

Indianapolis, IN—On Thursday, June 17, the IUPUI Center for Earth and Environmental Science (CEES) and Veolia Water Indianapolis will host Blue-Green Algal Blooms and Nutrients that Cause Them: Exploring Indiana’s Story at the Rathskellar Restaurant in downtown Indianapolis. This one-day symposium will bring together elected officials, government agencies, corporations, nonprofits, and universities to explore the causes, impact, and solutions for the increasingly common occurrence of blue-green algae in Midwest lakes and reservoirs.

General Sessions Offer Comprehensive Overview of Blue-Green Algal Issues

The general-session presentations offer a comprehensive overview of blue-green algal bloom issues, including environmental factors, innovative research, policy implications, and outreach solutions.

“In recent years, concern regarding the production and occurrence of blue-green algal blooms has grown in Central Indiana and nationally,” says CEES director Lenore Tedesco. “The blue-green algae that we often see on reservoirs during the summer months doesn’t just give water an unappealing look and musty taste and odor, it can also release toxins that can sicken people and animals.”

Researchers throughout the Midwest have been gathering data about blue-green algal blooms, exploring factors that influence growth and the potential impact on health and the environment. The morning sessions provide a forum for these researchers to share their findings with concerned citizens, businesses, and government agencies so the community can better understand and address the issues.

While environmental factors such as water temperature and water movement contribute to the growth of algae, nutrients are the main driver – and the only one that we can control. The afternoon sessions delve into current efforts to improve water quality and examine programs that monitor algae growth and the health of watersheds. Speakers include representatives from the Indiana Department of Environmental Management, the Upper White River Watershed Alliance and the Tippecanoe Watershed Foundation.

“Blue-green algae is fueled by a wide variety of nutrients, including discharges from sewage treatment plants and runoff from farm fields, livestock farms and lawns treated with fertilizers,” explained Lyn Crighton, executive director of the Tippecanoe Watershed Foundation. “The simple truth is that it is much more cost-effective to protect the many benefits provided by healthy watersheds than it is to restore them once they become impaired.”

Expert Panelists Debate Ways to Limit Algae Growth in Indiana Waterways

The Symposium will conclude with a lively panel discussion, Approaches to Limiting Phosphorus in Indiana Waterways.  Panelists will include State Senator Beverly Gard and State Representative Dick Dodge along with representatives from government agencies, universities, nonprofits and businesses that have an impact on our waterways.

A 2007 study by the U.S. Environmental Protection Agency found one of the toxins associated with algae present in 36 of 56 Indiana lakes. In November 2009, the state Legislature’s Environmental Quality Service Council recommended to direct the state’s environmental, health and natural resources departments to devise a strategy for monitoring algae levels.

“Taste and odor compounds produced by blue-green algae are one of the biggest treatment challenges for drinking water facilities in Indianapolis,” said David Gadis, president of Veolia Water Indianapolis, the contract operator of Indianapolis Water.  “Earlier this spring, Central Indiana experienced the wrath of Mother Nature when she unleashed high levels of algae, which surpassed current removal technologies---an impact felt by many drinking water customers. Helping to guide the stewardship of our water resources remains a critical activity for Veolia Water, which is why we’re committed to long-term global research and development on algae with CEES.”
