EPA Method 1664 Oil & Grease Testing in Wastewater
Understanding EPA Method 1664: The Environmental Protection Agency's (EPA) Method 1664 is a widely recognized standard for measuring oil and grease levels in wastewater. This method plays a crucial role in ensuring compliance with environmental regulations, particularly when it comes to the discharge of industrial wastewater into public sewers or surface waters.
The primary focus of EPA Method 1664 is to quantify the concentration of petroleum hydrocarbons (oil) and non-polar organic compounds (grease) using a combination of gravimetric analysis techniques. The method employs solvent extraction, followed by filtration and drying to determine the mass of oil and grease in milligrams per liter (mg/L). This approach ensures accurate measurement under various wastewater conditions.
The application of EPA Method 1664 is not limited to industrial settings; it also applies to municipal wastewater treatment plants. Compliance with this method helps facilities avoid penalties for exceeding allowable limits set by the Clean Water Act and other regulatory frameworks. By adhering to these standards, businesses can minimize their environmental impact and protect public health.
The testing process involves several critical steps:
- Sampling: Samples must be collected from a representative point in the wastewater stream using appropriate sampling techniques.
- Solvent Extraction: The sample is treated with a solvent (such as hexane) to extract oil and grease components.
- Filtration: After extraction, the mixture undergoes filtration through a specified filter to separate oil and grease from water.
- Drying: The filter containing the extracted materials is dried at elevated temperatures to evaporate residual solvents.
Each step requires precision to ensure accurate results. Our laboratory strictly adheres to EPA Method 1664, ensuring consistent and reliable test outcomes.

Applied Standards
EPA Method 1664 is based on internationally recognized guidelines that aim to standardize the measurement of oil and grease in wastewater. The method draws from several key international standards, including ISO and ASTM, which are widely accepted in both North America and Europe.
- ISO Standard: ISO 9278 provides a general framework for the extraction, separation, and determination of hydrocarbons in water samples. This standard complements EPA Method 1664 by offering broader context on best practices for hydrocarbon analysis.
- ASTM Standard: ASTM D1203 outlines procedures for determining oil and grease content in water using a Soxhlet extraction apparatus, which is similar to the solvent-based approach used in EPA Method 1664. This standard ensures consistency across different laboratories.
The use of these international standards enhances the reliability and accuracy of our testing services, ensuring that results are comparable with those from other reputable laboratories worldwide.
Our commitment to adhering to rigorous standards like EPA Method 1664, ISO, and ASTM guarantees that we provide clients with the most accurate and consistent data possible. This is essential for maintaining regulatory compliance and making informed decisions regarding wastewater management.
