Abstract:  THE BLOSENSKI LANDFILL SITE IS LOCATED ON 13.6 ACRES IN WEST CALN TOWNSHIP, CHESTER COUNTY, PA. THE SITE IS BORDERED BY HEAVILY WOODED AND AGRICULTURAL AREAS. APPROXIMATELY 467 RESIDENTS LIVE WITHIN ONE MILE OF THE SITE. BEGINNING IN THE 1950S THE SITE OPERATED AS A LANDFILL ACCEPTING MUNICIPAL AND INDUSTRIAL WASTES. IN 1971 THE SITE WAS PURCHASED BY MR. JOSEPH BLOSENSKI, WHO OPERATED THE LANDFILL UNTIL THE EARLY 1980S. WASTES WERE RANDOMLY DUMPED ON THE SURFACE DURING THE OPERATING PERIOD, AND INCLUDED SOLVENTS, WASTE WATER TREATMENT SLUDGES, DEMOLITION AND CONSTRUCTION WASTES, UNDERCOATING MATERIALS AND OPEN AND LEAKING DRUMS. NUMEROUS CITIZEN COMPLAINTS OF ODORS, SMOKE AND AIRBORNE DEBRIS LED TO PETITION AND REGULATORY ACTIONS AGAINST MR. BLOSENSKI. IN 1982, EPA CONDUCTED A SITE INSPECTION AND FOUND SERIOUS GROUND WATER CONTAMINATION. THE PRIMARY CONTAMINANTS OF CONCERN ARE VOCS INCLUDING BENZENE, TOLUENE AND TCE, AND INORGANICS INCLUDING LEAD, CADMIUM, CHROMIUM AND MERCURY.

THE SELECTED REMEDIAL ACTION FOR THE SITE WILL BE CONDUCTED IN FOUR PHASES. PHASE I - INSTALLATION OF A PUBLIC WATER SUPPLY TO 12 RESIDENCES; PHASE 2 - EXCAVATION AND REMOVAL OF BURIED DRUMS AND OTHER MATERIAL WITH OFFSITE DISPOSAL IN A RCRA LANDFILL; PHASE 3 - PERFORM A PRE-DESIGN STUDY TO FURTHER SAMPLE GROUND AND SURFACE WATERS TO DELINEATE EXTENT AND MAGNITUDE OF CONTAMINATION. BASED ON THE RESULTS OF THE STUDY, GROUND WATER WILL BE PUMPED AND TREATED FOR A MAXIMUM OF TWO YEARS TO ACLS ESTABLISHED BY EPA; PHASE 4 - INSTALL A LOW PERMEABILITY RCRA COVER ON THE LANDFILL, DIVERT SURFACE WATER AND CONSTRUCT A GAS VENTING SYSTEM. PHASES 1-3 WILL BE IMPLEMENTED CONCURRENTLY. ESTIMATED CAPITAL COST OF THE REMEDY RANGES BETWEEN $11,000,000 AND $15,000,000, WITH A BASELINE COST OF $13,000,000. O&M COSTS ARE ESTIMATED TO BE $534,300 FOR THE FIRST TWO YEARS.
 
Remedy:  THE SELECTED REMEDY WILL BE PERFORMED IN A PHASED APPROACH, WITH THE FIRST THREE OF THE FOUR PHASES BEING PERFORMED CONCURRENTLY. PHASE 1

INSTALL A PUBLIC WATER SUPPLY LINE TO AN ESTIMATED TWELVE (12) RESIDENCES. THE WATER WILL BE PROVIDED BY THE COATESVILLE WATER AUTHORITY. EPA WILL PAY FOR THE INITIAL CONNECTIONS TO THESE RESIDENCES. PHASE 2

EXCAVATE AND REMOVE BURIED DRUMS IN AREAS IDENTIFIED DURING EPA'S REMEDIAL INVESTIGATION AND ANY MATERIAL IN INTIMATE CONTACT WITH THE DRUMS, AND FREE STANDING LIQUID, AND DISPOSE OF THESE MATERIALS AT A RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) FACILITY. IN ADDITION, EPA WILL PERFORM TRENCHING OPERATIONS THROUGHOUT OTHER AREAS OF THE SITE IN ORDER TO IDENTIFY, EXCAVATE AND DISPOSE OF OTHER BURIED DRUMS. PHASE 3

PERFORM A PRE-DESIGN STUDY WHICH SHALL INCLUDE FURTHER SAMPLING OF RESIDENTIAL WELLS, SURFACE, WATERS, AND THE INSTALLATION OF ADDITIONAL MONITORING WELLS AND CONDUCTING PUMP TESTING TO MORE FULLY DELINEATE THE EXTENT AND MAGNITUDE OF THE GROUND WATER CONTAMINATION. THIS STUDY WILL ALSO BE USED TO COLLECT DATA FOR THE DESIGN OF AN EFFECTIVE GROUND WATER PUMPING AND TREATMENT SYSTEM.

BASED ON THE FINDINGS OF THE PRE-DESIGN STUDY, IMPLEMENT A SOURCE REDUCTION PROGRAM INVOLVING PUMPING AND TREATING OF CONTAMINATED GROUND WATER FOR SOME PERIOD OF TIME DETERMINED DURING DESIGN NOT TO INITIALLY EXCEED TWO YEARS TO ALTERNATE CONCENTRATION LEVELS DEVELOPED BY EPA. THIS WILL INCLUDE THE CONSTRUCTION OF AN ON-SITE TREATMENT FACILITY TO TREAT THE GROUND WATER. AFTER THIS SPECIFIED PERIOD, AN EVALUATION WILL BE MADE BY EPA AS TO THE EFFECTIVENESS OF THE PUMPING AND TREATMENT FOR REDUCING THE GROUNDWATER CONTAMINATION TO EPA APPROVED CONCENTRATION LEVELS AND FOR THE NEED, EXTENT AND DURATION OF FUTURE GROUNDWATER REMEDIATION. PHASE 4

INSTALL A LOW PERMEABILITY COVER ON THE LANDFILL IN ACCORDANCE WITH THE REQUIREMENTS OF RCRA. CONSTRUCT APPROPRIATE SURFACE WATER DIVERSION SYSTEM(S).

IF NEEDED, CONSTRUCT A GAS VENTING SYSTEM TO PROTECT THE COVER. AN AIR MONITORING PROGRAM WILL BE CONDUCTED AT THESE GAS VENTS AND TREATMENT OF THE GASES WILL BE PROVIDED, IF NEEDED.

INSTITUTE PERIODIC MONITORING FOR GROUND WATER AND SURFACE WATER CONTAMINATION IN THE LANDFILL AREA IN COMPLIANCE WITH RCRA CLOSURE REGULATIONS. THIS WILL INCLUDE SAMPLING OF SELECTED RESIDENTIAL AND/OR MONITORING WELLS IN ADDITION TO SURFACE WATER SAMPLING.
