Abstract:  THE DORNEY ROAD LANDFILL SITE IS LOCATED IN LEHIGH COUNTY, PENNSYLVANIA. THE SITE IS APPROXIMATELY 27 ACRES, BOUNDED ON THE EAST BY DORNEY ROAD, AND EXTENDS WESTWARD SUCH THAT THE SOUTHWEST CORNER IS IN LONGSWAMP TOWNSHIP, BERKS COUNTY. LAND USE IN THE AREA IS RURAL, RESIDENTIAL AND AGRICULTURAL. THE POPULATION WITHIN AN 0.25 MILE RADIUS OF THE SITE IS ESTIMATED TO BE APPROXIMATELY 20 PEOPLE. CURRENTLY, 1 RESIDENCE IS LOCATED WITHIN 1,000 FEET OF THE SITE AND 3 RESIDENCES ARE WITHIN 2,000 FEET OF THE SITE. THE WATER SUPPLY FOR THESE NEARBY HOMES IS GROUND WATER FROM PRIVATE WELLS. THE MAJORITY OF THE SITE IS PRESENTLY OWNED BY R. EMORY MABRY. BEGINNING IN 1952, AN ABANDONED IRON MINE PIT ON THE SITE WAS USED AS AN OPEN DUMP. FROM 1966 TO 1978, AN UNPERMITTED LANDFILL WAS OPERATED IN THE SAME MINE PIT. IN 1986, EPA CONDUCTED A REMOVAL ACTION AND REGRADED THE LANDFILL TO PREVENT RUNOFF AND EROSION OF LANDFILL MATERIAL FROM MIGRATING TO NEIGHBORING PROPERTY. IN 1980 AND 1982, EPA INVESTIGATIONS REVEALED ELEVATED LEVELS OF VOCS, METALS AND PHENOLS IN GROUND WATER AND LEACHATE SAMPLES. THIS REMEDIAL ACTION WILL PREVENT DERMAL CONTACT AND INCIDENTAL INGESTION OF LANDFILL SOIL AND SOLID WASTE. IT WILL ALSO MINIMIZE THE CONTINUED LEACHING OF PRECIPITATION AND ONSITE PONDED WATERS THROUGH THE CONTAMINATED LANDFILL. A SUBSEQUENT REMEDIAL ACTION WILL ADDRESS THE GROUND WATER UNDER THE SITE. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE SOIL, GROUNDWATER AND SURFACE WATER ARE VOCS INCLUDING BENZENE, TOLUENE AND XYLENES, METALS INCLUDING ARSENIC AND CHROMIUM, AND OTHER ORGANICS INCLUDING PHENOL AND PAHS.


THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES: OFFSITE DISPOSAL OF APPROXIMATELY 700,000 GALLONS OF ONSITE POND WATER; CONSTRUCTION OF A DIKE AND DIVERSION DITCH SYSTEM TO CONTROL RUNON/RUNOFF; REGRADING AND INSTALLATION OF A MULTI-LAYER LANDFILL CAP AND A GAS COLLECTION SYSTEM; GROUND WATER MONITORING; AND DEED AND ACCESS RESTRICTIONS. THE ESTIMATED PRESENT WORTH COST FOR THIS REMEDIAL ACTION IS $14,000,000 WITH ESTIMATED ANNUAL O&M COSTS OF $42,000.
 
Remedy:  THIS INITIAL OPERABLE UNIT WAS DEVELOPED TO PROTECT PUBLIC HEALTH AND THE ENVIRONMENT BY PREVENTING DERMAL CONTACT AND INCIDENTAL INGESTION OF LANDFILL SOIL AND SOLID WASTE. IT WILL ALSO MINIMIZE THE CONTINUED LEACHING OF PRECIPITATION AND ON-SITE PONDED WATERS THROUGH THE CONTAMINATED LANDFILL MEDIA, THEREBY ISOLATING THE SOURCE OF GROUND WATER CONTAMINATION. A SUBSEQUENT OPERABLE UNIT ADDRESSING THE GROUND WATER UNDER THE SITE IS FORTHCOMING.

THE SELECTED SITE REMEDY IS PROTECTIVE OF HUMAN HEALTH AND THE ENVIRONMENT, WILL ATTAIN THE APPLICABLE OR RELEVANT AND APPROPRIATE REQUIREMENTS OF OTHER FEDERAL AND STATE ENVIRONMENTAL LAWS, AND IS COST-EFFECTIVE.

THE MAJOR COMPONENTS OF THE SELECTED REMEDY ARE AS FOLLOWS:

* ELIMINATION OF ON-SITE PONDED WATERS
* REGRADING
* PENNSYLVANIA-TYPE MULTI-LAYER CAP
* RUNON/RUNOFF CONTROLS
* RUNOFF MONITORING
* GROUND WATER MONITORING
* PERIMETER FENCE
* DEED NOTICE
