The study will receive matching funds to look at ways to potentially reduce the smell at Lake Lanier as well.

According to state Sen. Drew Echols, the funding is being used for what he called a “Lake Lanier Taste & Odor Study.”

The Budget Conference Committee included the funding “to focus on the immediate concerns caused by taste and odor issues in Lake Lanier and the Chattahoochee River,” inspired in part by recent problems.

“We need to get a handle on reasons for the rate and severity of the taste and odor problems in Lake Lanier,” Echols said in a statement. “The $2 million in funding for a study will help us understand the underlying issues, plan for ways to mitigate future occurrences and ultimately lead to treatment options to get our water tasting great again.”
