EPA 2019 Thallium Emerging Contaminant Test in Water
The EPA's 2019 update on emerging contaminants introduced stringent testing protocols for various chemicals, including thallium. This test is critical given the increasing concern over trace levels of metals that can have adverse effects on human health and ecosystems.
Thallium, a heavy metal with toxic properties, has been identified as an emerging contaminant due to its potential to enter water systems through various pathways such as industrial runoff, mining activities, and accidental releases. The EPA's 2019 guidelines outline the need for rigorous testing to ensure compliance with drinking water standards.
The test involves a multi-step process that begins with sample collection from suspected sources of contamination. Proper sampling is crucial as it directly affects the accuracy of the results. Once collected, the samples are transported under controlled conditions to prevent degradation or contamination. The next step is preparing the samples for analysis, which includes diluting if necessary and ensuring they meet the required pH levels.
The analytical method used by Eurolab for this test complies with EPA Method 2019. This involves using inductively coupled plasma mass spectrometry (ICP-MS) for quantification. ICP-MS is selected due to its high sensitivity and precision, enabling the detection of trace amounts of thallium even at parts per billion levels.
The acceptance criteria are stringent; results must be within ±5% of the actual concentration if a standard reference material (SRM) is used. This ensures reliability and accuracy in detecting thallium in water samples.
