This fact sheet provides an update on RemedialInvestigation activities at the Jacksonville and RogersRoad Landfill Superfund sites. Work is beingconducted concurrently at these sites which are locatedwithin one-half mile of each other.

BackgroundThe City of Jacksonville operated the Jacksonville

and Rogers Road sites as municipal landfills until themid 1970's. The sites were closed when the ArkansasDepartment of Pollution Control and Ecology(ADPCE) refused to grant permits for continued useof the landfills due to the high water table and poordrainage in the area.

The Jacksonville and Rogers Road Landfill siteswere brought to the attention of the EnvironmentalProtection Agency (EPA) as potential Superfund sitesin 1983 and 1985, respectively. Citizens' complaintsalleged that hazardous wastes had been acceptedduring landfill operations. In 1987 the landfills wereplaced on EPA's National Priorities List of potentiallyhazardous waste sites and became eligible for long-term remedial actions through the Superfund program.

The Remedial Investigation

Remedial Investigation field work was initiatedin September 1988. The purpose of the investigationis to identify the presence and extent of on-site andoff-site contaminant levels, to assess the potentialmigration of contaminants, and to determine site-related risks, if any. The investigation and associatedreports usually require 18 months to complete.Activities at the Jacksonville and Rogers Road sitesincluded a systematic investigation of soil, sediment,on-site drums, surface water, and groundwater.

Phase I of the investigation was completed ir\§March 1989. During this phase, the soil at each silt-was sampled at systematic grid locations. Samples alsowere collected from waste piles, trenches^ediment^soil, groundwater, surface water, and drums. Heav,equipment was used to conduct soil borings and on-site excavations to determine the extent ofcontamination. Drilling equipment was used to installa total of 20 groundwater monitoring wells. Samplesfrom these wells and from residential wells were takenfor analysis. A topographic survey was also completedduring this phase. Information from this survey willbe used to develop a detailed site map.

During Phase II, all monitoring wells wereresampled, additional soil samples were collected, andhydrogeologic tests were conducted to determineaquifer characteristics beneath the sites. The secondphase of field work was completed in May.

Samples taken during the Remedial Investigationwere analyzed for organics, inorganics,pesticides/PCBs, herbicides, and dioxins/furans. EPAand ADPCE have received most of the analyticalresults from the laboratory analysis and theinformation is currently being evaluated.

Initial assessment of the data indicates the.presence of high concentrations of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in corrodeddrums at isolated locations on the Jacksonville andRogers Road sites. TCDD concentrations range fromfive to 220 ppb in drum samples from the JacksonvilleLandfill and from non-detectable to 14.5 ppb in theRogers Road drum samples; contaminated soil volumesare estimated at 3000 cubic yards and 5000 cubicyards, respectively. Dioxin was not detected in anyoff-site samples taken from the residential propertyadjacent to the sites, nor were dioxins detected in anygroundwater samples.

TCDD is a probable human carcinogen andcontact with the skin can cause severe irritation.TCDD attaches to soil and sediment, but does notdissolve easily in water. Although TCDD has not beendetected offsite, a potential health hazard exists to"nvone who comes in contact with the contaminatedJii in the drum areas.

Opportunities for InvolvementAfter the sampling data has been analyzed, EPA's

contractor will prepare the RemedialInvestigation/Feasibility Study Reports. These reportswill provide results of the investigation and willinclude an assessment of the potential risks posed bythe contaminants at the Jacksonville and Rogers Roadsites. The Feasibility Study will analyze alternativeswhich may be used to remedy the sites.

EPA will conduct a public comment period afterthe reports become available. During this period thepublic will have an opportunity to comment on allalternatives in writing and-at a public meeting,'currently scheduled for the summer of 1990. EPA andADPCE will consider all public comments and thenselect a remedial action to address the contaminants ateach site.
