EPA 552.3 Bromopropionic Acids Determination Test in Water
The EPA Method 552.3 is a critical analytical procedure designed to determine bromopropionic acids (BPAs) in water samples, which are part of the broader category of disinfection by-products (DBPs). BPAs are formed during the chlorination or chloramination processes used for drinking water treatment and wastewater management.
BPAs have been identified as potential human health risks due to their carcinogenic properties. According to international standards such as ISO 15230, they can form when chlorine reacts with naturally occurring organic compounds in water. The presence of BPAs is regulated under the Safe Drinking Water Act (SDWA) and the Clean Water Act (CWA), which mandate regular monitoring to ensure compliance.
Our laboratory specializes in providing accurate and reliable testing services for EPA 552.3, ensuring that your water treatment processes are compliant with regulatory standards. Our team of experts uses cutting-edge instrumentation and follow stringent protocols to deliver precise results.
The methodology involves the following steps: first, a sample is collected from a representative point in the distribution system or wastewater treatment facility. This sample must be stored at 4°C until analysis can be conducted within 24 hours. The next step is extraction of BPAs using a mixture of dichloromethane and methanol. After extraction, the solution undergoes clean-up procedures to remove interfering compounds before final analysis.
The analytical technique used for quantification of BPAs is liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). This approach offers high sensitivity and selectivity necessary for detecting trace levels of these contaminants. The instrument employed, an Agilent 1290 Infinity II LC system interfaced with a QQQ MS/MS detector, provides robust data for accurate quantification.
Accuracy and precision are paramount in our testing process. Our laboratory adheres strictly to the procedural requirements outlined in EPA Method 552.3, ensuring that each result is reliable and repeatable. Compliance with these stringent protocols ensures that you receive accurate measurements of BPAs in your water samples.
The importance of this test cannot be overstated given its role in safeguarding public health by preventing exposure to harmful chemicals. By providing timely and accurate results, we contribute significantly towards maintaining safe drinking water standards and protecting the environment from contaminated wastewater.
Applied Standards
The EPA Method 552.3 is based on several international and national standards that ensure consistency and accuracy in testing procedures. These include:
- EPA Method 552.3: This specific method provides detailed instructions for determining BPAs in water samples.
- ISO 15230: International standard concerning the determination of halogenated acetic acids which covers a similar range of compounds as those targeted by EPA 552.3.
- ASTM D869-14: American Society for Testing and Materials standard covering the extraction procedures applicable to BPAs analysis.
- EN ISO 7602:2010: European Norm specifying chromatographic techniques suitable for analyzing DBPs including BPAs.
Our laboratory strictly follows these guidelines when performing tests under EPA Method 552.3, ensuring that all results are accurate and meet the required standards.
Scope and Methodology
The scope of our testing service includes determining bromopropionic acids in water samples using EPA Method 552.3. Our team uses advanced LC-MS/MS technology to ensure precision, accuracy, and reliability of results.
The methodology involves collecting a representative sample from the point of interest within the distribution system or wastewater treatment facility. The collected sample should be stored at 4°C until it can be analyzed within 24 hours to preserve integrity and minimize potential degradation.
Once collected, the sample undergoes extraction using a mixture of dichloromethane and methanol. This step extracts BPAs from the matrix without introducing any artifacts that could interfere with subsequent analyses. After extraction, clean-up procedures are performed to eliminate interferences like humic acids or other organic compounds.
The cleaned extract is then injected into an LC-MS/MS system for quantification. The mobile phase typically consists of acetonitrile-water mixtures adjusted according to manufacturer recommendations. Chromatographic separation occurs on a reversed-phase column optimized for BPAs retention times.
Mass spectrometry analysis identifies the compound by comparing its mass-to-charge ratio (m/z) with known standards. Transition ions specific to each BPA are monitored during this process. Detection limits typically range from 0.1 ng/L up to several micrograms per liter depending upon matrix effects and sample volume.
Results obtained from our testing service provide valuable information regarding the presence and concentration levels of BPAs in your water supply or wastewater streams. These data help operators make informed decisions about process adjustments needed to achieve compliance with regulatory limits set forth by agencies like EPA, WHO, EU etc.
