IRP Site 74 - Old Skeet Range

From the late 1960s to the early 1990s, skeet shooting activities took place at Site 74. Contaminants of concern identified in studies include the metals lead and antimony, and polyaromatic hydrocarbons, in site soil and sediments, which could pose significant ecological risk due to Site 74’s proximity to the Seal Beach National Wildlife Refuge. A Feasibility Study took place in FY 2013 to evaluate remedial action alternatives that are appropriate for the site, including combinations of excavation, capping, and no action. The Navy’s planned action will balance wetlands habitat protection with the reduction of risk to wildlife from contaminants.  The Navy is currently developing a proposed plan for the final remedy selection.
