ASTM D5673 Chromium Test in Water
The ASTM D5673 standard specifies a method for determining hexavalent chromium (Cr(VI)) in water. This test is crucial for industries and municipalities that must ensure compliance with environmental regulations regarding heavy metals in water.
This service supports the accurate measurement of Cr(VI) levels, which can pose health risks if present in drinking water or industrial wastewater at high concentrations. The method is designed to identify and quantify hexavalent chromium, a potent carcinogen according to the U.S. Environmental Protection Agency (EPA).
The ASTM D5673 test involves several key steps: sample preparation, digestion of samples using nitric acid, and subsequent analysis via spectrophotometric means or ion chromatography. The precision and accuracy of this method are critical for regulatory compliance.
Our laboratory adheres strictly to the ASTM standards to ensure reliable results. Each sample is processed in a controlled environment, ensuring consistent performance across all tests. Our team of experts ensures that every step from sample collection to final analysis meets the highest quality control measures.
The test provides critical information for stakeholders involved in water treatment processes and wastewater management. Compliance with ASTM D5673 not only helps meet regulatory requirements but also contributes significantly to environmental sustainability by ensuring safe levels of heavy metals in water.

Environmental and Sustainability Contributions
The ASTM D5673 test plays a pivotal role in environmental sustainability by helping industries and municipalities comply with stringent regulations on heavy metals in water. By accurately measuring hexavalent chromium levels, this method ensures that the water meets or exceeds safety standards set forth by regulatory bodies.
Our laboratory's adherence to these standards not only supports compliance but also promotes a safer environment for communities relying on clean drinking water. By detecting and quantifying heavy metals like Cr(VI), we contribute to reducing health risks associated with contaminated water sources.
This service aligns with global sustainability goals by aiding in the reduction of environmental impact from industrial activities that discharge pollutants into water bodies. It supports a circular economy approach by ensuring that resources used are not compromised through contamination, thereby promoting long-term ecological balance and human well-being.
