Abstract:  THE HELEVA LANDFILL SITE CONSISTS OF A 20-ACRE LANDFILL LOCATED ON A 93-ACRE TRACT OF LAND IN LEHIGH COUNTY, PENNSYLVANIA. THE SITE IS SURROUNDED PRIMARILY BY FARM AND PASTURELANDS, WITH THE VILLAGE OF ORMROD (POPULATION APPROXIMATELY 100) AND TOWN OF IRONTON (POPULATION 150) LOCATED APPROXIMATELY ONE QUARTER MILE AWAY. THE SITE BEGAN OPERATIONS AS A SANITARY LANDFILL IN 1967, ACCEPTING 250-350 TONS/DAY OF MIXED REFUSE INCLUDING PAPER, WOOD, AND ORCHARD WASTES. IN ADDITION, INDUSTRIAL WASTES WITH HIGH LEVELS OF TRICHLOROETHYLENE (200 UG/L) WERE SENT TO THE SITE AS EARLY AS 1967. THE SITE WAS CLOSED IN MAY OF 1981 BY THE PENNSYLVANIA DEPARTMENT OF ENVIRONMENTAL RESOURCES BECAUSE OF OPERATIONAL DEFICIENCIES.

THE SELECTED REMEDY FOR THE HELEVA LANDFILL SITE CONSISTS OF EXTENDING AN EXISTING WATER MAIN FROM ORMROD TO IRONTON, CAPPING THE ENTIRE 20-ACRE LANDFILL ACCORDING TO RCRA STANDARDS, CONSTRUCTING SURFACE WATER DIVERSION AND GAS VENTING SYSTEMS, CONDUCTING A PRE-DESIGN STUDY TO FULLY DELINEATE THE SOURCE OF CONTAMINATION AND DETERMINE SINK HOLE ACTIVITY, CONSTRUCTING A TREATMENT FACILITY ONSITE, PUMPING AND TREATING HIGHLY CONTAMINATED GROUND WATER, MONITORING AND SAMPLING EXISTING WELLS AND SURFACE WATER, AND CONDUCTING OPERATIONS AND MAINTENANCE FOR A PERIOD OF AT LEAST TWO YEARS. THE TOTAL CAPITAL COST OF THE SELECTED REMEDIAL ALTERNATIVE IS ESTIMATED TO BE $7,253,000. ANNUAL O&M COSTS ARE ESTIMATED TO BE $62,000.
 
Remedy:  - PROVIDE AND INSTALL AN ALTERNATE WATER SUPPLY BY EXTENDING AN EXISTING 12" WATER MAIN APPROXIMATELY 1 MILE FROM ORMROD TO IRONTON.
- INSTALL A CAP ON THE 20 ACRE LANDFILL THAT MEETS ALL THE REQUIREMENTS OF THE RESOURCES CONSERVATION AND RECOVERY ACT (RCRA).
- CONSTRUCTION OF A SURFACE WATER DIVERSION SYSTEM.
- CONSTRUCTION OF A GAS VENTING SYSTEM WITH MONITORING AND POSSIBLE TREATMENT.
- A PRE-DESIGN STUDY WHICH WILL INVOLVE TEST BORINGS TO MORE FULLY DELINEATE THE LOCATION AND MAGNITUDE OF THE SOURCE OF CONTAMINATION AND TO DETERMINE IF COLLECTION OF THIS SOURCE WILL BE EFFECTIVE IN REDUCING THE CONTAMINATION OVER THE EXTENT OF THE CONTAMINATED AREA. THE PRE-DESIGN STUDY WILL ALSO DETERMINE THE EXISTENCE AND MAGNITUDE OF SINKHOLE ACTIVITY IN THE AREA.
- BASED ON THE FINDINGS OF THE PRE-DESIGN STUDY, A SOURCE REDUCTION PROGRAM INVOLVING PUMPING AND TREATING OF HIGHLY CONTAMINATED GROUND WATER FROM THE LANDFILL WILL BE IMPLEMENTED.
- A TREATMENT FACILITY WILL BE CONSTRUCTED ONSITE AND WILL TREAT THE WASTEWATER DOWN TO APPROVED CONCENTRATION LEVELS BEFORE DISCHARGE INTO COPLAY CREEK.
- A MONITORING PROGRAM DURING AND SUBSEQUENT TO THE REMEDIAL ACTION. THIS INCLUDES MONITORING IN COMPLIANCE WITH RCRA REGULATIONS, MONITORING OF EXISTING MONITORING WELLS AND PERIODIC SAMPLING AND ANALYSIS OF POTENTIALLY AFFECTED SURFACE WATER IN THE AREA.
- OPERATION AND MAINTENANCE WILL BE IMPLEMENTED BY THE STATE OF PENNSYLVANIA ON THE LANDFILL CAP, GAS VENTING SYSTEM, SURFACE WATER DIVERSION SYSTEM AND MONITORING PROGRAM SIX MONTHS AFTER CONSTRUCTION OF THESE SYSTEMS. THE SOURCE REDUCTION AND TREATMENT SYSTEM WILL BE OPERATED AS A REMEDIAL ACTION FOR A PERIOD OF AT LEAST TWO YEARS AND WILL BE ELIGIBLE FOR TRUST FUND MONIES.
