Del Amo site OU1, Soils and NAPL (Non-Aqueous Phase Liquid) refers to contamination remaining in the shallow and deep soils on the Del Amo site. NAPL refers to a phase of contamination in the ground which is characterized by liquids that are not easily dissolved in water. Since the site has largely been redeveloped, the contamination exists underneath buildings, and correspond with the structures that used to exist when the site operated as a rubber manufacturing plant. The Record of Decision (ROD) for Del Amo OU1 was issued in 2011:
