EPA Method 1664

EPA Method 1664 is a standardized testing process used to measure concentrations of certain organic compounds, specifically hydrocarbons, in water samples. It involves collecting a water sample, filtering out solids, and then extracting the hydrocarbons using a special solvent. The extracted chemicals are then analyzed with sensitive instruments like gas chromatography to determine their levels. This method helps regulators and industries monitor water quality, ensuring that harmful hydrocarbons are kept within safe limits and environmental or health risks are minimized.
