Experts prescribe Algimycin to reduce taste-and-odor challenge:

Algaecide product tailored to combat MIB

By Chad Lawson, Spartanburg Water Communications

OUR WATERSHEDSpartanburg Water’s efforts to reduce the presence of taste-and-odor-causing algae byproducts in its reservoirs are following the experts’ prescription of a familiar medicine: Algimycin, an environmentally friendly algaecide whose key ingredient is copper, a standard element in best-practice approaches to algae removal.

The algaecide application was administered by trained professionals on Lake Bowen earlier this month, and was also applied to portions of Municipal Reservoir Number 1 on Friday, July 27. Preliminary results indicate that the most recent treatments were successful. The company performing the applications, Aqua Services Inc., has done the same work for multiple utilities across the U.S., including the Tennessee Valley Authority, Georgia Power, Mississippi Power and U.S. Steel, among others.

Algimycin, which has been certified by the National Sanitation Foundation as a safe treatment for use in drinking water resources like Lake Bowen, is viewed by the experts as among the best options for combating MIB, or Methylisoborneol.

That’s why Dr. John Rodgers Jr., a professor and director of the Ecotoxicology Program at the Clemson College of Agriculture, Forestry and Life Sciences, prescribed a specifically calculated dose of Algimycin to reduce the presence of MIB this month on both Lake Bowen and Municipal Reservoir Number 1. It’s a product that is familiar to many on the utility’s water quality team: Rodgers first prescribed Algimycin in 2015, when MIB spikes began occurring that summer. 

Dr. Rodgers said, for example, that algae growing in a little less than 15 percent of Lake Bowen that were producing taste-and-odor compounds were treated with about 190 parts per billion of Algimycin. But is it safe?

“Absolutely; it's safe," Dr. Rodgers said. “This algaecide has been thoroughly tested for safety for non-target species such as fish. The concentration and prescription that I developed for Spartanburg Water’s use are not toxic to fish.”

But, like any other medicine, Dr. Rogers said, it must be administered by a trained professional.

“Those warning labels for algaecide can be scary because they highlight the risks from encountering the undiluted form of the product,” he said. “Even warning labels for over-the-counter medicine can be frightening when your read them. I’ve been doing this work for many years, and our team stands behind the safety and efficacy of the algaecides that we use.”

Following a significant fish loss on both reservoirs following an algaecide application to treat Geosmin, a different algae byproduct in May, Dr. Rodgers has been working with a multidisciplinary team to determine the best methods to not only fight the effects of algae, but also ensure the safety of fish in the ecosystem. A different algaecide, Current, was used in the May application. Dr. Rodgers said a number of environmental factors were likely the cause of fish loss—not a single and limited application of algaecide.

Although fish loss is a known potential side effect of algaecide use, products like Algimycin and Current are recognized as best practices in the safe reduction of taste-and-odor causing algae byproducts when prescribed by experts like Dr. Rodgers and managed by trained and licensed applicators. In fact, Aqua Services Inc., whose team has performed all of Spartanburg Water's algaecide applications since 2015, counts world-renowned bass fisherman Bill Dance among its many clients.

Water quality and safety are the number one factors in determining the best algae-reduction methods, said Ken Tuck, Director of Water Treatment. Tuck said that the application was successful in protecting our community's drinking water source from certain algae that may cause taste-and-odor concerns.

“We want our customers and the entire community of people who enjoy the lake and rely on it for drinking water to know that it is safe,” Tuck said. “Our goal is reliability. This method, and this product, are widely used across the country in the reduction of taste-and-odor-causing algae.”

Dr. Rodgers said that the challenges associated with ecosystem balance—and lake management—are not unique to Spartanburg Water. Recent reports of algae blooms have underscored the importance of studying the underlying causes for the frequency with which they’re occurring across the country.

“This is targeted algae management,” he said. “To take what we’ve learned so that the people of Spartanburg and this region can have the quality drinking water that they’ve become accustomed to. Spartanburg Water is doing an amazing job with managing their water resources.”
