Nutrient pollution levels at Lake Lanier are high for a second year in a row, according to the environmental group Chattahoochee Riverkeeper.
High levels of nutrients cause algae blooms. Large amounts of algae can affect water treatment plants and the taste and smell of drinking water. They can have negative effects on fish and other wildlife in the lake, too, said Jason Ulseth, riverkeeper at Chattahoochee Riverkeeper.
“We’re not seeing human health impacts, we’re not seeing wildlife impacts, based off of the data we’re collecting right now,” he said.
But, he said, things could get worse.
“The nutrient levels and the algae levels are getting higher and higher over the past few years,” he said. “It’s a call to action that we have to be working to reduce the amount of nutrients coming into the lake so that it can be healthy for future generations.”
Ulseth says improving wastewater treatment plants, making sure septic systems are in good shape and fertilizing lawns near the lake less would all help.
