An Environmental Baseline Investigation was performed at AF Miljøbase Vats in Rogaland, Southwest Norway. The contamination of seafloor sediments, well-water and soil was analyzed, and the occurrence of anthropogenic debris and biological state at the bottom outside the facility was investigated with an ROV. The results show that the sediments are contaminated with TBT (SFT Class IV, TA-2229/2007) and PAH (Class II), but not at a higher level than was previously shown. The remaining components (As, Ba, Cd, Co, Cr, Cu, Hg, Mo, Ni, P, Pb, V, Zn, PCBs, 5CB, alpha- and gamma-HCH, HCB, OCS, DDE, DDD, MBT, DBT, MPT, DPT and TPT) in sediments close to the site were either in Class I (background), not included in TA-2229/2007, or not detected. This includes mercury that leaked into the bays between 2004 and 2006. The well-water was not contaminated, whereas soil samples were slightly contaminated with zinc and arsenic just above the SFT norm for sensitive land use. Large rocks and metallic debris are found along the shore, smothered with rock-dust due to the recent expansion of the quay areas. The biological state is typical for a quay area in this region.
