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 BOD5 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 O2), a vinegar manufacturer (ultimate BOD = 80 mg/L O2) and a pharmaceutical company (ultimate BOD = 200 mg/L O2).
