EPA 644 Chromium Certification Test in Water
The EPA Method 644 is a comprehensive analytical procedure designed to determine hexavalent chromium (Cr(VI)) concentrations in water samples. This test is crucial for ensuring the safety and compliance of drinking water sources, industrial wastewater discharges, and other regulated water bodies. Hexavalent chromium has been classified as a carcinogen by the U.S. Environmental Protection Agency, making accurate and reliable testing essential.
Our laboratory adheres strictly to EPA Method 644, utilizing state-of-the-art instrumentation and experienced personnel to deliver precise results that meet or exceed regulatory standards. The test involves several critical steps, including sample collection, filtration, digestion, and analysis using validated methods such as inductively coupled plasma mass spectrometry (ICP-MS) or atomic absorption spectroscopy (AAS).
The EPA 644 method is particularly important for industries subject to strict environmental regulations, including manufacturing, power generation, mining, and metal plating. Compliance with this standard can prevent costly fines and reputational damage from non-compliance. Additionally, regular testing helps ensure long-term safety of water sources.
Our laboratory provides a complete suite of services for EPA 644 compliance, offering both single sample analysis and batch testing capabilities. We offer flexible turnaround times to accommodate clients' schedules while maintaining the highest standards of accuracy and precision. Our team of experts is dedicated to providing timely results that are critical for regulatory reporting.
| Standard Reference | Description |
|---|---|
| EPA Method 644 | Determination of Hexavalent Chromium in Drinking Water and Wastewater by Spectrophotometry or Flame Atomic Absorption Spectrometry. |
| ASTM D1253-08(2017) | Test Method for Determination of Hexavalent Chromium in Water by Colorimetric Methods. |
Applied Standards
The EPA method is the primary standard used across the United States to ensure accurate and consistent measurement of hexavalent chromium in water. This method has been refined over years of use, incorporating feedback from industry and regulatory bodies.
In addition to the EPA Method 644, ASTM D1253-08(2017) provides an alternative colorimetric approach that is often used for preliminary screening or when specialized equipment is not available. Both methods are complementary and should be considered based on specific requirements.
The use of these standards ensures that the laboratory results are comparable to those from other accredited laboratories, thereby enhancing the reliability of regulatory decisions.
