ABSTRACT

At the end of 2019, US EPA proposed the first major revision of the Lead and Copper Rule (LCR) since 1991. Although the proposed rule is still under revision, it is essential for environmental laboratories to be ready for responding to the potential increase in analytical demands associated with the revised LCR. In this work, we validated method EPA 200.8 with ICP/MS 2030 and analyzed tap water samples from various sources to determine the stability and robustness of the system. The poster will demonstrate that the method performed well according EPA Quality Assurance criteria for target metals included in EPA 200.8, providing a robust solution for supporting the LCR monitoring requirements as well as meeting other federal regulations. Outcomes from the evaluation of tap water samples will be also presented.
