The EBL consistently employs the use of established SOPs, instrument performance verification, and data validation. In addition to multiple levels of internal laboratory quality control, EBL participates in USGS round robin; an external laboratory performance verification analysis. Depending on the sample set, the EBL invests almost 30% of our sample load to quality assurance.  The EBL always meets the quality objectives of the analytical method, and it is our purpose to provide an excellent individual data user quality control framework when needed.

In addition to sample summaries, our clients get full consultations on data quality. Each sample batch is accompanied by strict QAQC data so that our clients can feel confident about their analysis.
