EPA 608 Organochlorine Organic Compounds Test in Water
The EPA 608 method is a critical analytical procedure designed to detect and quantify organochlorine compounds (OCCs) present in water samples. These compounds, including DDT, chlordane, and polychlorinated biphenyls (PCBs), have been widely used in the past for agricultural and industrial purposes. However, due to their persistence in the environment and potential health risks, strict regulations govern their presence in drinking water and wastewater.
The EPA 608 method is based on gas chromatography with electron capture detection (GC-ECD), which provides high sensitivity and selectivity for OCCs. This technique allows for accurate quantification of these compounds even at very low concentrations, ensuring that water supplies meet stringent safety standards.
Preparation of the sample involves several steps to ensure accuracy and precision. First, the water sample is filtered through a pre-cleaned filter to remove particulate matter and other contaminants. Then, the filtrate undergoes solvent extraction using dichloromethane or another suitable solvent. The extract is concentrated by evaporation before injection into the GC-ECD system.
The EPA 608 method specifies rigorous quality control measures to ensure reliable results. This includes calibration with known standards, analysis of blank samples and spiked blanks to account for matrix effects, and regular maintenance of the analytical equipment. The method also allows for confirmation using additional techniques like mass spectrometry (MS) if required.
Accurate reporting is essential for regulatory compliance and public health protection. Results are typically reported in parts per billion (ppb), with detailed documentation of the entire analytical process, including sample collection, preparation, analysis, and calibration.

The importance of this test cannot be overstated, especially given the long half-lives and bioaccumulative nature of many organochlorines. Regular monitoring helps to prevent contamination from spreading into larger water systems or ecosystems. It also supports compliance with environmental regulations such as the Clean Water Act.
Why It Matters
The EPA 608 organochlorine test is crucial for ensuring public health and protecting aquatic environments from contamination by persistent organic pollutants. Organochlorines can bioaccumulate in food chains, leading to potential adverse effects on human health and wildlife.
By conducting this test regularly, water utilities can identify and address sources of contamination early, preventing the spread of harmful substances into larger systems. This proactive approach not only meets regulatory requirements but also enhances trust with customers by demonstrating a commitment to safe and clean drinking water.
The results from EPA 608 testing are used in various ways: - To evaluate the effectiveness of treatment processes. - To identify potential sources of contamination upstream or within the distribution network. - To track trends over time, helping utilities plan for future challenges.
Failure to adhere to these standards can have severe consequences, including legal penalties, reputational damage, and increased operational costs. Therefore, it is essential that water treatment facilities invest in robust testing programs to maintain compliance and ensure the safety of their water supplies.
