 One interviewee stated that "many drums of liquid" (identified as oil, organic solvents and water) were dumped north of the Sayen House between 1969 and 1971.Another reported that the location's hydraulic presses leaked "large amounts of lubricating oil," which eventually made its way into a "creek across Mercer Street" via a floor drain.Another interviewee corroborated this account, but stated the practice stopped in 1969, when the company began collecting the oil in drums and dumping it directly "onto the ground from the Sayen House."
