THE SITUATION Once the GES systems were installed in the facilities, monitoring of the effluent began. The study lasted two months in six of the seven restaurants; the Bee Ridge store was monitored for 5 months. At the conclusion of the test, an effluent sample was extracted from each restaurant and tested for grease and oil levels.

THE DOCUMENTATION Dramatic reductions in grease and oil levels were achieved in every one of the seven locations. The before & after G&O clearly demonstrate the effectiveness of the Environmental Biotech (GES) Grease Eradication System in the McDonald's facilities.

McDonald's Orlando, Florida
The City of Orlando conducts quarterly samplings of effluent from food facilities to ensure these facilities are not discharging high-strength wastewater concentrations into the public sewer system. This effluent is then tested for Biological Oxygen Demand (BOD) levels. In September of 1992, the City of Orlando took an effluent sample from the McDonald's facility located at Highway 436 and Hoffner. Subsequent testing of the sample registered a BOD level of 950 mg/l.
