EPA 639 Perchlorate Compliance Test in Water
The EPA Method 639 is a widely recognized standard used to determine perchlorate concentrations in water samples. This method is critical for ensuring compliance with regulatory standards set by the United States Environmental Protection Agency (EPA). Perchlorate, an oxidizer commonly found in rocket propellants and explosives, can leach into groundwater or surface waters through improper disposal practices.
Perchlorate contamination poses significant health risks. It can interfere with thyroid function by blocking iodine uptake, which is essential for the production of thyroid hormones. This makes accurate and reliable testing crucial to protect public health and ensure compliance with environmental regulations. The EPA Method 639 employs a combination of ion chromatography and post-column derivatization techniques to achieve precise results.
Our laboratory strictly adheres to EPA Method 639 for perchlorate testing, ensuring accurate, reproducible results that meet the highest standards set by regulatory bodies. We use state-of-the-art instrumentation such as high-performance liquid chromatographs (HPLCs) equipped with post-column derivatization systems to achieve the required sensitivity and specificity.
Sample preparation is a critical step in achieving reliable test results. Samples are typically filtered through 0.45 micron filters, followed by acidification with nitric acid to pH 2-3. This step helps stabilize perchlorate ions and prevents potential interferences from other anions present in the sample.
The testing process involves injecting a known volume of the prepared sample into the HPLC system. The mobile phase used is typically a mixture of acetonitrile and water with phosphoric acid, optimized to separate perchlorate ions efficiently from other interfering ions. Post-column derivatization allows for enhanced detection by converting perchlorate ions into a more readily detectable form.
After the analysis, results are reported in parts per billion (ppb). Compliance is determined based on the specified regulatory limits set forth by the EPA and any local or state regulations that may apply. This method provides the necessary precision to differentiate between background levels of perchlorate and contamination above acceptable thresholds.
The accuracy and reliability of our testing services are further enhanced by rigorous quality control measures, including internal audits, proficiency testing programs, and continuous training for our technical staff. Our laboratory is accredited under ISO/IEC 17025:2017, ensuring that all tests meet international standards.
By offering EPA Method 639 compliance testing, we provide essential support to industries such as water utilities, chemical manufacturers, and waste management companies. These entities rely on accurate perchlorate levels to ensure safe drinking water and comply with environmental regulations. Our services contribute significantly to the protection of public health and the environment.
