EPA 552 Haloacetic Acids Compliance Test in Drinking Water
The EPA 552 compliance test is a critical measure to ensure that drinking water meets the stringent standards set by the United States Environmental Protection Agency (EPA). This test specifically targets haloacetic acids, which are formed during chlorination or chloramination processes. Compliance with this standard not only ensures safe and potable water but also helps in maintaining public health.
Water utilities across North America rely on this test to meet the National Primary Drinking Water Regulations (NPDWR) established by the EPA. The Haloacetic Acids group, which includes compounds like dichloroacetic acid (DCAA), trichloroacetic acid (TCAA), monochloroacetic acid (MCAA), and others, has a maximum contaminant level (MCL) of 60 parts per billion (ppb). This limit is critical because these acids can be carcinogenic if present in water supplies above the specified threshold.
The testing process involves several stages to ensure accuracy. The first step is collecting a representative sample from the water source or distribution system. Once collected, the samples undergo rigorous preparation procedures that may include filtration and preservation methods to maintain the integrity of the compounds being tested.
Instrumentation used for this test includes high-performance liquid chromatography (HPLC) equipped with UV detection. The HPLC method is chosen due to its precision in separating complex mixtures, making it ideal for identifying individual haloacetic acids within the sample. Chromatograms are generated and analyzed against known standards to determine the concentration of each compound.
The EPA 552 test also requires meticulous quality control measures throughout the entire process, from sampling through final analysis. This includes using certified reference materials (CRMs) for calibration purposes and employing trained personnel who adhere strictly to standard operating procedures (SOPs).
Compliance testing is just one aspect of maintaining safe drinking water; however, it plays a pivotal role in ensuring public health protection against potentially harmful contaminants. By adhering to EPA guidelines, water utilities can demonstrate their commitment to providing clean and safe water while simultaneously protecting themselves from potential legal consequences.

Use Cases and Application Examples
- Treatment Plant Monitoring: Regular testing helps monitor treatment plant operations to ensure that chlorination or chloramination processes are optimized for both efficiency and safety.
- Distribution System Surveillance: Continuous monitoring of distribution systems ensures that water quality remains consistent from source to tap, even after the water has been distributed through complex networks.
- New Facility Commissioning: During the initial stages of building a new facility, compliance testing serves as part of comprehensive validation protocols required before official operation begins.
- Facility Expansion: As facilities grow or expand services, periodic retesting ensures that any changes in water quality do not violate regulatory standards.
