Our comprehensive QA/QC program meets or exceeds the rigorous criteria established by the United States Environmental Protection Agency (EPA) and State Agencies. Energy Laboratories is certified under the Safe Drinking Water Act by Region VIII EPA, and the States of Idaho, Montana, Nevada, North Dakota, South Dakota, Washington, and Wyoming. Samples received at Energy Laboratories are under a strict monitoring and tracking system from log-in to completion. Samples are logged in immediately upon receipt and are carefully checked for any special handling that may be needed. All analytical procedures, sample handling, and preservation techniques are EPA approved (where applicable) and strictly adhered to. We duplicate every tenth sample to measure and control the precision of our work. Where applicable, we also spike every tenth sample to test our accuracy. Reference samples from the EPA or from private sources are tested by the laboratory with every set of samples to provide a third measure of the performance of our equipment and personnel.
