EPA 643 Antimony Compliance Test in Drinking Water
The EPA 643 Antimony Compliance Test is a critical procedure designed to ensure that drinking water meets the stringent quality standards set forth by the United States Environmental Protection Agency (EPA). This test specifically targets antimony, an element known for its potential adverse health effects when present in water supplies. The primary objective of this compliance test is to guarantee that the levels of antimony do not exceed the Maximum Contaminant Level Goal (MCLG) and the enforceable MCL set by EPA.
The EPA's regulations under the Safe Drinking Water Act require public water systems to monitor for various contaminants, including antimony. The test procedure outlined in EPA Method 643 is essential for compliance with these regulations. This method involves a series of steps designed to ensure accurate and reliable results:
- Sample Collection: Proper collection of water samples is crucial as it ensures the integrity of the testing process. Samples should be collected in clean, amber-colored containers to prevent light-induced degradation.
- Precipitation and Filtration: After collection, the sample may undergo precipitation to remove interfering ions or particles that could affect the test results. Filtration is then performed to ensure the sample is clear of suspended solids.
- Acidification: The filtered sample is acidified using nitric acid (HNO₃) to pH 2, which stabilizes the antimony and prevents further degradation or precipitation.
- Sample Storage: Proper storage conditions are essential. Samples should be kept refrigerated at temperatures below 4°C until analysis can be conducted within five days of collection.
The analytical method typically involves flame atomic absorption spectrophotometry (FAAS) or graphite furnace atomic absorption spectrophotometry (GFAAS), both of which are capable of providing precise and accurate results. These methods allow for the detection of antimony at very low concentrations, ensuring that even trace amounts can be detected and quantified.
The EPA's MCL for antimony in drinking water is 0.05 mg/L (ppb), as per the Safe Drinking Water Act regulations. Compliance with this limit is critical to protect public health from potential adverse effects of long-term exposure to elevated levels of antimony, which can include neurological and cardiovascular issues.
Non-compliance with EPA standards not only poses health risks but also carries severe legal and financial implications for water utilities. Regular testing and compliance with these regulations are therefore paramount. Our laboratory employs state-of-the-art equipment and experienced technicians to ensure accurate and timely results, providing peace of mind for water utilities and compliance officers.
Our service includes not only the testing itself but also comprehensive reporting that details the test methodology, results, and any necessary corrective actions. This documentation is invaluable for maintaining regulatory compliance and ensuring water safety for consumers.

Environmental and Sustainability Contributions
The EPA 643 Antimony Compliance Test plays a crucial role in environmental protection by ensuring that drinking water meets stringent quality standards. By preventing the release of antimony into the environment, we contribute to the sustainability of our natural resources.
Antimony is known for its persistence and bioaccumulation properties, meaning it can persist in the environment for long periods and accumulate in organisms. Excessive levels of antimony in water bodies can disrupt aquatic ecosystems and affect human health through contaminated food chains. Our testing service helps mitigate these risks by identifying and addressing any contamination issues early.
Through our compliance services, we also promote sustainable practices within the water sector. By ensuring that water utilities meet regulatory requirements, we encourage the adoption of best practices in water treatment and management. This not only protects public health but also fosters a more sustainable approach to resource use.
