Former Naval Air Facility (NAF) Adak, Adak Island, AK

GCE was subcontracted to prepare the Quality Assurance Project Plan (QAPP) in accordance with the Uniform Federal Policy (UFP)-QAPP, Department of Defense (DoD) Policy and Guidelines for Acquisitions Involving Environmental Sampling or Testing, applicable regulatory guidance documents, and U.S. Navy instructions. The QAPP includes DoD Quality Systems Manual (QSM) Version 5.1 Appendix B Table B-15, utility clearance, and dig permits, and defined project objectives and associated data needs and described DQOs. The QAPP also contained the conceptual site model (CSM). At the time of award, the only PFAS compounds that have EPA-derived toxicity values were perfluorobutanesulfonic acid (PFBS), perfluorooctanoic Acid (PFOA) and perfluorooctane sulfonate (PFOS).
