Abstract:  THE 300-ACRE INDUSTRIAL EXCESS LANDFILL SITE IS IN UNIONTOWN, STARK COUNTY, OHIO. SEVERAL HUNDRED RESIDENCES ARE WITHIN A HALF MILE OF THE SITE, AND ALL RESIDENCES AND BUSINESSES IN THE UNIONTOWN AREA RELY ON GROUND WATER FROM PRIVATE WELL SUPPLIES. SURFACE WATER AT THE SITE FLOWS TO METZGER DITCH WHICH IS LOCATED ALONG THE EASTERN BORDER OF THE SITE. THE SITE WAS OPERATED AS A MIXED INDUSTRIAL AND REFUSE LANDFILL FROM 1966 UNTIL 1980. LARGE AMOUNTS OF FLY ASH AND LIQUID WASTES INCLUDING LATEX AND SPENT ORGANIC SOLVENTS WERE DISPOSED OF IN THE LANDFILL BETWEEN 1968 AND 1972. TO PREVENT THE SPREAD OF CONTAMINANTS ASSOCIATED WITH THESE WASTES, SEVERAL EMERGENCY ACTIONS HAVE BEEN UNDERTAKEN. IN 1986 AN ACTIVE METHANE EXTRACTION SYSTEM WAS INSTALLED TO PREVENT THE OFFSITE MIGRATION OF EXPLOSIVE LEVELS OF METHANE GAS. IN APRIL 1987 EPA INSTALLED AIR STRIPPERS IN EIGHT RESIDENCES AND TWO BUSINESSES DUE TO THE PRESENCE OF LOW LEVELS OF VOLATILE ORGANIC COMPOUNDS. IN SEPTEMBER 1987 EPA SIGNED A RECORD OF DECISION (ROD) TO PROVIDE AN ALTERNATE WATER SUPPLY TO 100 HOMES WEST OF THE SITE TO ENSURE THAT THE COMMUNITY RECEIVED SAFE DRINKING WATER WHILE THE FINAL REMEDIAL ACTION FOR THE SITE WAS IMPLEMENTED. THIS ROD REPRESENTS THE FINAL REMEDIAL ACTION FOR THE SITE AND ADDRESSES THE SOURCE AREA, GASES GENERATED WITHIN THE SOURCE AREA, AND CONTAMINATED GROUND WATER. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE SOIL, SEDIMENTS, AND GROUND WATER ARE VOCS INCLUDING BENZENE, VINYL CHLORIDE, AND PCE; OTHER ORGANICS INCLUDING CARCINOGENIC PAHS; AND METALS. AIR CONTAMINATION BY METHANE GAS IS ALSO PRESENT AT THE SITE.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES INSTALLING A MULTILAYER RCRA CAP OVER THE SITE TO PREVENT SURFACE WATER INFILTRATION; EXPANDING THE EXISTING METHANE VENTING SYSTEM TO ACCOMMODATE THE POTENTIAL INCREASE OF LANDFILL GAS DUE TO THE CAP; EXTRACTING AND TREATING APPROXIMATELY 256 MILLION GALLONS OF CONTAMINATED GROUND WATER BY AIR STRIPPING, CARBON ADSORPTION, AND FLOCCULATION/SEDIMENTATION/FILTRATION TO ACHIEVE COMPLIANCE WITH CLEAN WATER ACT NPDES DISCHARGE CRITERIA FOR SURFACE WATER DISCHARGE; CONTINUING THE PUMPING OF GROUND WATER TO MAINTAIN A LOWERED WATER TABLE AND PROTECT GROUND WATER FROM ADDITIONAL CONTAMINATION BY THE LANDFILL; TREATING SURFACE WATER FROM PONDS AT THE SITE, IF NECESSARY; AND DREDGING SEDIMENT FROM THE PONDS AND DITCH AND INCORPORATING THEM UNDER THE CAP; MULTIMEDIA MONITORING; AND INSTITUTIONAL CONTROLS RESTRICTING FUTURE USE OF THE SITE. THE ESTIMATED PRESENT WORTH COST FOR THIS SELECTED REMEDIAL ACTION IS $18,548,000, WHICH INCLUDES AN ESTIMATED ANNUAL O&M COST OF $440,000.
 
Remedy:  THIS REMEDIAL ACTION IS THE FINAL ACTION FOR THE INDUSTRIAL EXCESS LANDFILL, INC. (IEL) SITE. IN SEPTEMBER 1987, US EPA SIGNED A RECORD OF DECISION FOR PROVISION OF AN ALTERNATE WATER SUPPLY TO APPROXIMATELY 100 HOMES NEAR IEL WHOSE DRINKING WATER IS AFFECTED OR THREATENED BY CONTAMINANTS FROM IEL. THIS FINAL REMEDIAL ACTION ADDRESSES THE WASTE DISPOSAL AREA AND THE LANDFILL GAS GENERATION AND GROUNDWATER CONTAMINATION ASSOCIATED WITH THE WASTE DISPOSAL AREA. THE REMEDY ADDRESSES THE PRINCIPAL THREATS POSED BY IEL BY ISOLATING AND CONTAINING WASTES WITHIN THE LANDFILL, EXPANDING THE EXISTING METHANE VENTING SYSTEM FOR THE COLLECTION AND FLARING OF LANDFILL GAS, AND BY EXTRACTING AND TREATING CONTAMINATED GROUND WATER BENEATH AND NEAR THE LANDFILL. ADDITIONAL STUDIES OF LANDFILL GAS GENERATION AND POTENTIAL MIGRATION, SURFACE STABILITY AND HYDROLOGY, AND HYDROGEOLOGIC CHARACTERISTICS AND CONTAMINANT FATE AND TRANSPORT MUST BE CONDUCTED DURING THE DESIGN PHASE OF THE REMEDY TO COLLECT APPROPRIATE INFORMATION FOR DESIGN OF THE VARIOUS TREATMENT AND CONTAINMENT SYSTEMS.

THE MAJOR COMPONENTS OF THE IEL REMEDY INCLUDE;

* INSTALLATION OF A RCRA SUBTITLE C COMPLIANT CAP OVER THE ENTIRE SURFACE OF THE LANDFILL WITH SURFACE WATER DRAINAGE CONTROL AND DISCHARGE;
* EXPANSION OF THE EXISTING METHANE VENTING SYSTEM;
* EXTRACTION AND TREATMENT OF CONTAMINATED GROUNDWATER BENEATH AND NEAR THE LANDFILL UNTIL CLEANUP LEVELS ARE ACHIEVED;
* PUMPING OF GROUNDWATER TO MAINTAIN THE WATER TABLE LEVEL BENEATH THE BOTTOM OF THE WASTES IN IEL IN ORDER TO PROTECT GROUNDWATER FROM ADDITIONAL CONTAMINATION BY THE LANDFILL;
* INSTALLATION OF FENCING AROUND THE PERIMETER OF THE SITE;
* USE RESTRICTIONS ON FUTURE USE OF THE SITE PROPERTY; AND
* MONITORING OF THE CAP, GROUND WATER EXTRACTION AND TREATMENT SYSTEM, AND METHANE VENTING SYSTEM TO ENSURE THE REMEDY IS EFFECTIVE.
