Del Monte Corp. (Oahu Plantation)
The Del Monte Corp. (Oahu Planation) Superfund site is near Kunia Village in Honolulu County, Hawaii. The Del Monte Corporation (Del Monte) grew and processed pineapples on the 6,000-acre plantation from about 1946 to 2006. The company used pesticides to control worms. In 1977, there was an accidental 500-gallon pesticide spill next to the Kunia drinking water supply well. The spill and years of pesticide storage and processing have contaminated soil and groundwater. EPA added the site to the National Priorities List (NPL) in 1994. Del Monte began treating groundwater in 2004. It continues to operate all cleanup systems. Del Monte leased the site from the James Campbell Company, the property owners, until the Oahu Plantation ceased operation in 2006. After the plantation closed, the James Campbell Company sold more than half of the land to Kunia Loa Ridge Farmlands. The organization encourages affordable small-scale sustainable farms while reducing soil erosion and improving the quality and availability of local water sources. Kunia Loa Ridge Farmlands resells small plots to farmers to grow tropical fruits and raise livestock. In 2004, EPA took the 3,000-acre Puamoho part of the site off the NPL. This area is home to more reuse activities. In 2007, an agricultural company bought 2,300 acres of the former Oahu Plantation for seed corn production. A beauty products company moved its headquarters and manufacturing operations to a 10,000-square-foot facility at the site in 2011. The U.S. Army also bought part of the site property to expand housing for Schofield Barracks. Commercial, public service and residential reuses are also on site.
