EPA 552.2 Trichloroacetic Acid Determination Test in Water
The Water & Wastewater Testing service offered by our laboratory is aimed at ensuring the safety and quality of water resources across various sectors including municipal supply, industrial processes, and recreational facilities. One critical aspect within this domain is the determination of disinfection by-products (DBPs), which are formed when disinfectants such as chlorine interact with organic matter in water.
The EPA 552.2 method specifically targets Trichloroacetic Acid (TCAA) as a key DBP, which is known for its potential adverse effects on human health at elevated levels. This test is essential not only for compliance with regulatory standards but also to maintain the integrity of water systems and protect public health.
The EPA 552.2 method involves several steps including sample collection, pretreatment if necessary, extraction using a suitable solvent, and subsequent analysis by high-performance liquid chromatography (HPLC) with ultraviolet detection. The precision of this method is critical as even small concentrations of TCAA can have significant impacts on water quality.
The acceptance criteria for the test are stringent, ensuring that results meet or exceed regulatory limits set forth in 40 CFR Part 141. Compliance with these standards is crucial for water utilities and industrial plants that rely on clean, safe water.
Our laboratory adheres to international best practices and uses state-of-the-art equipment to ensure accurate and reliable results. We employ a team of experienced scientists who are well-versed in this methodology to provide you with the most precise determinations possible.
Scope and Methodology
| Step | Description |
|---|---|
| Sample Collection | Water samples are collected from specified locations using certified containers to ensure they do not contaminate the sample. |
| Pretreatment (if required) | The sample may undergo filtration or other treatments before extraction to remove interfering substances. |
| Extraction | TCAA is extracted from the water using dichloromethane, followed by evaporation and derivatization with N,N-dimethylformamide (DMF). |
| Analysis | The extract is then analyzed via HPLC equipped with a fluorescence detector to quantify TCAA levels. |

Use Cases and Application Examples
- Municipal water supply systems ensuring compliance with EPA regulations.
- Industrial plants monitoring DBP formation during chlorination processes.
- Research institutions studying the impact of TCAA on aquatic ecosystems.
- Recycling facilities assessing the quality of reclaimed water.
| Application Example | Description |
|---|---|
| Municipal Water Supply Compliance | A local city is required to monitor TCAA levels in its drinking water supply. Using our EPA 552.2 testing, they can ensure that their water meets the stringent limits set by the EPA. |
| Industrial Process Monitoring | An industrial plant uses chlorine for disinfection and wishes to minimize DBP formation. By regularly analyzing TCAA levels using this method, they can adjust their processes accordingly. |
| Aquatic Ecosystem Research | Scientists studying the impact of TCAA on fish populations in a local river use our testing services to gather data that informs conservation efforts. |
| Water Recycling Facilities | Recycling facilities ensure the quality of reclaimed water by regularly testing for TCAA. This helps them meet environmental standards and customer expectations. |
