A truck dumped industrial waste into a pit. They found the truck 3 days ago with a pure pool of waste. Your lab finds the BOD5 of this waste to be 80 mg/L with a k=0.1/day. What was the waste source? Here are the 3 nearby suspects: Winery BOD ultimate = 275 mg/L Vinegar manufacturer BOD ultimate = 80 mg/L Pharmaceutical BOD ultimate = 200 mg/L
