EPA Method 1664 Oil & Grease in Groundwater
The Environmental Protection Agency's (EPA) Method 1664 is a standardized procedure designed to quantify oil and grease in groundwater. This method uses ultraviolet-visible spectrophotometry to determine the presence of hydrocarbons, which are typically indicative of petroleum products such as oil and grease. The primary application of this test is for environmental compliance monitoring, particularly when assessing the impact of spills or releases into groundwater systems.
The EPA Method 1664 is widely used in various sectors including municipal water supply, industrial facilities, and environmental consulting firms. Compliance with this method ensures that groundwater quality meets regulatory standards set by the EPA and other relevant authorities. This testing procedure helps prevent contamination of drinking water sources and protects ecosystems from harmful pollutants.
The method involves several critical steps to ensure accurate measurement results. First, a known volume of groundwater is collected using appropriate sampling techniques. Then, the sample undergoes preliminary filtration or centrifugation if necessary to remove suspended solids that could interfere with spectrophotometric readings. After preparation, the sample is analyzed in triplicate on an ultraviolet-visible spectrophotometer set at specific wavelengths.
The choice of wavelength and other parameters are crucial for accurate measurement according to EPA Method 1664. The selected wavelengths target characteristic peaks associated with aromatic hydrocarbons present in oil and grease compounds. By comparing the absorbance values obtained from these measurements against calibration curves prepared beforehand, analysts can calculate concentrations of total petroleum hydrocarbons (TPH) within the groundwater.
Accurate results are essential for effective decision-making regarding corrective actions needed to address contamination issues or maintain compliance with legal requirements. Laboratories performing this analysis must adhere strictly to all procedural aspects outlined in EPA Method 1664 to produce reliable data. Rigorous quality control measures and inter-laboratory comparisons further enhance the credibility of test outcomes.
Understanding the scope of application for EPA Method 1664 provides insight into its importance within environmental monitoring programs. This method enables precise quantification of hydrocarbon contamination in groundwater, aiding stakeholders in identifying sources of pollution and implementing appropriate remediation strategies.
Applied Standards
EPA Method 1664 is specifically designed to comply with the standards set by the United States Environmental Protection Agency. This method aligns closely with international guidelines like ISO 8063, which provides recommendations for oil and grease analysis in water samples.
The procedural steps outlined in EPA Method 1664 are meticulously crafted to ensure consistency across different laboratories performing this type of analysis. Compliance with these methods helps maintain high standards of accuracy and reliability necessary for regulatory compliance purposes.
By adhering strictly to the protocols specified by EPA Method 1664, analysts can generate data that is valid not only under domestic regulations but also internationally accepted criteria such as those found in EN ISO 9001 and AS/NZS ISO 17025 standards for laboratory accreditation.
