This wasn’t a truck spill, but I thought it was interesting enough to include.

About 8,000 liters of the concentrate used to make the soft drink Sunny D, formerly known as Sunny Delight spilled into a creek in England in May, 2006. The spill killed dozens of fish, which is a little scary. The spill was caused by a crack in an underground fiberglass tank at the Gerber Foods Soft Drink factory in Bridgwater, Somerset. The tank was used to hold sub-standard juice waiting for disposal.
