A midnight dumper discharges a truck load of industrial waste in a gravel pit. Three days after the truck is spotted, a sample of the remaining pool of pure waste is collected and is sent to laboratory for forensic analyses. Test results indicate that sample has a BODs of 80 mg/L O2 with a rate constant of 0.1/day. Three nearby factories generate organic wastes: a winery (ultimate BOD = 275 mg/L 02), a vinegar manufacturer (ultimate BOD 80 mg/L O2) and a pharmaceutical company (ultimate BOD -200 mg/L 02). You are the team of forensic experts here: Determine the source of waste.
