STOCKTON, Calif. — Don’t be alarmed if you see pink or purple water along the Stockton waterfront this week as the Department of Water Resources studies algae.
According to the city of Stockton, the studies involve applying a non-harmful dye to the water to record its flow and monitor how McLeod Lake and the San Joaquin River interact. Researchers are trying to figure out what causes harmful algal blooms on the waterfront.
The EPA says the rhodamine dye used in the study is non-harmful to humans and the environment, though the sight of it may surprise onlookers as it turns the water bright pink or purple. The color is temporary.
The first study will be completed by Friday, Aug. 30. A second study will happen in early 2025.
