Gas station biodiesel storage tank leak likely culprit for fishkill in Tennessee

In Tennessee, a storage tank at a gas station in northern Scott County is expected to be the source of up to 5,000 gallons of biodiesel that has leaked into a nearby creek, leading to at least 2,000 dead fish. The state’s department of natural resources is investigating the spill and hopes to have an answer soon. The gas station that is the likely culprit has already installed aerators downstream with the aim of offsetting future leakages. The fishkill is due to lack of oxygen in the water as biodiesel itself is not toxic.
