Color change in Georgia Southern ponds attributed to algae control chemical

The ponds on the Georgia Southern University campus appear to have changed color after being refilled from maintenance.

The change in color can be attributed to a copper chemical that was added to the ponds to control algae growth, Communications Director Jennifer Wise said based on information from Facilities Services. 

“The blue coloring of the water, is from a planted pond maintenance by Landscaping and Grounds Services,” Wise said in an email.

Biology Department Professor, Stephen Vives explained how algal growth can be a concern for ponds like those on the Georgia Southern University campus.

“Algal growth can be of concern in ponds that are receiving runoff which can include fertilizers and other sources of nutrients,” Vives said in an email. “It really depends on the type of algae that grows as to the undesired effects.”

Vives said typical undesired effects from algae growth includes ponds being unsightly or smelly.

“In addition, submergent plant and algal blooms can result in decomposition that reduces oxygen levels for fishes,” Vives said in an email. The dye helps control submerged plant and algal growth by reducing the light needed for their growth. The dye won’t eliminate the growth completely.”

Wise said the copper chemical is non-toxic and will not have any negative effects on the wildlife.
