EPA 934 Lead 210 Determination Test in Water
The EPA Method 934 is a critical analytical procedure designed to determine lead-210 (Pb-210) in water samples. This test is particularly important for environmental monitoring, especially in the context of radioactive contamination. Lead-210, an alpha-emitting radionuclide produced by the decay of uranium and thorium series isotopes, can accumulate in aquatic environments, posing potential health risks if not properly managed.
Accurate measurement of Pb-210 concentration is essential for regulatory compliance, environmental assessment, and public health protection. The EPA 934 method involves several key steps: sample collection, filtration, digestion, and final analysis using liquid scintillation counting (LSC). This process ensures that the lead-210 present in water samples can be accurately quantified.
The test is widely used by regulatory agencies such as the Environmental Protection Agency (EPA) to ensure compliance with drinking water standards. The method's precision and accuracy are crucial, as even small variations in Pb-210 levels could indicate significant environmental changes or potential health hazards.
Understanding the context of EPA 934 is important for various stakeholders, including quality managers, compliance officers, R&D engineers, and procurement specialists. The method's application in water testing highlights its importance in ensuring safe drinking water and protecting public health. By adhering to this standard, laboratories can provide reliable data that informs policy decisions and environmental management practices.
| Sample Type | Expected Pb-210 Range (Bq/L) |
|---|---|
| Groundwater | 0.1–1 Bq/L |
