mg/L as a maximum limit of oil and grease. However, the MOP did not specify the importance of the origin of the FOG, which could be either petroleum or animal and vegetable. WEF’s MOP3 (1973) cited levels of FOG in domestic wastewaters to be in the range of 16 mg/L-105 mg/L. They further recommended limits on petroleum-based oil at

can be utilized successfully for the determination of oil and grease in water samples. The method shows good linearity and precision, with a detection limit below 0.5 mg/L. Tetrachloroethylene was found to be a suitable solvent for this analysis, and has a much lower environmental impact than the previously favored solvents such as CFC-113

For example, if an oil/water separator is used to store waste oils and spills, any contact water entering the oil/water separator could result in the discharge of oil and grease in exceedance of permit limits.
