EPA Superfund Program: ARKWOOD, INC., OMAHA, AR

Superfund Site Profile

Current Status

The EPA is currently conducting a dioxin re-evaluation for the site. In addition, the EPA continues to conduct Five Year Reviews (FYRs) of the site remedy. These FYRs ensure that the site soil and groundwater remedies remains protective of human health and the environment. The latest FYR was completed September 30, 2016.

 Site Background

The 18-acres site is located in a valley on Cricket Creek Road, bounded by ridges covered with native trees, approximately one-half mile southwest of Omaha, Arkansas, and west of the old U.S. Highway 65. The site operated as a wood treater from 1962 to 1984 and is presently inactive. New Cricket Spring is located down valley immediately west of the site.

                                   
The Arkwood, Inc, site operated as a wood treater from 1962 to 1984 and is presently inactive. The site is approximately one-half mile southwest of Omaha, Arkansas, and lies to the west of the old U.S. Highway 65. The site consists of an approximately 18-acres parcel that slopes gently toward the northwest. It is located in a valley on Cricket Creek Road, bounded by ridges covered with native trees. The site is generally sparsely vegetated and covered with gravel and rocks mixed with native, clayey soils. The site is in an area of karst geology that is characterized by subsurface fractures and channels. New Cricket Spring is located down valley immediately west of the site.

National Priorities Listing History              
National Priorities List (NPL) Proposal Date:  September 4, 1985
NPL Final Date:  March 31, 1989

 Soil Remedy:
The 1990 ROD specified that all site soil containing greater than: 300 mg/kg pentachlorophenol, 20 mg/kg dioxin as 2,3,7,8-tetrachlorodibenzo-p-dioxin, and 6.0 mg/kg carcinogenic polynuclear aromatic hydrocarbons as benzo(a)pyrene equivalents, were to be incinerated onsite.  An Explanation of Significant Difference (ESD) was issued on June 14, 1995. The ESD changed the onsite incineration remedy component to incineration at an offsite facility.

Ground Water Remedy:
The 1990 ROD specified that treatment at New Cricket Spring was required, if after two years following completion of the soil remedy, the water quality at the spring did not meet Arkansas Water Quality Standards. Since the spring continued to exceed standards after the two year period, installation of a water treatment system was initiated. The EPA determined that this remedy was protective of human health and the environment, attained federal and state requirements that are applicable or relevant and appropriate, was cost effective compared to equally environmentally protective alternatives, and utilized permanent solutions and alternative treatment technologies to the maximum extent practicable.
