Abstract:  THE 19-ACRE CRYO-CHEM SITE IS A METAL FABRICATION FACILITY IN WORMAN, EARL TOWNSHIP, BERKS COUNTY, PENNSYLVANIA. LAND USE IN THE AREA IS SEMI-RURAL, WITH A WOODLAND AREA LOCATED NORTHEAST OF THE SITE, AND AN ONSITE STREAM WEST OF THE CONTAMINATED AREA. BETWEEN 1970 AND 1982, CHEMICAL SOLVENTS WERE USED AT THE FACILITY AT A RATE OF TWO TO THREE 55-GALLON DRUMS PER YEAR. DURING THIS TIME, A CHEMICAL SPILL OCCURRED AT CRYO-CHEM, BUT CANNOT BE DEFINITELY LINKED TO THE SOURCE OF CONTAMINATION. WELL SAMPLING CONDUCTED BETWEEN 1985 AND 1987 SHOWED GROUND WATER CONTAMINATION IN MONITORING AND RESIDENTIAL WELLS WITHIN 1 MILE OF THE SITE, WHICH LED TO A REMOVAL ACTION THAT REQUIRED THE INSTALLATION OF ACTIVATED CARBON FILTER UNITS IN 20 AFFECTED HOMES. EPA HAS DIVIDED THE SITE INTO THREE OPERABLE UNITS (OUS) FOR REMEDIATION. A 1989 RECORD OF DECISION (ROD) ADDRESSED OU1, THE CONTAMINATED DRINKING WATER, BY PROVIDING AN ALTERNATE WATER SUPPLY. A 1990 ROD ADDRESSED THE REMEDIATION OF GROUND WATER USING AIR STRIPPING AND CARBON ABSORPTION AS OU2. THIS ROD ADDRESSES CONTAMINATION IN SOIL CAUSED BY PAST FACILITY OPERATIONS, WHICH CONTINUES TO LEACH FROM THE SOIL INTO THE GROUND WATER SYSTEM. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE SOIL ARE VOCS INCLUDING TCA, TCE, DCA, AND PCE.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES SAMPLING THE AREA TO BETTER DEFINE THE EXTENT OF THE CONTAMINATION; TREATING THE CONTAMINATED SOIL ONSITE USING VAPOR EXTRACTION; CONTROLLING AIR EMISSIONS USING CARBON ABSORPTION, AND DISPOSING OF, OR REGENERATING, ANY SPENT CARBON; DISCHARGING ANY WATER CAPTURED DURING IN-SITU VAPOR EXTRACTION TO THE PUMP AND TREAT SYSTEM CURRENTLY UNDER DESIGN; AND CONDUCTING CONFIRMATION SOIL SAMPLING AND AIR MONITORING. THE ESTIMATED PRESENT WORTH COST FOR THIS REMEDIAL ACTION RANGES FROM $53,500 TO $66,400 BASED ON THE TREATMENT SELECTED. THERE ARE NO O&M COSTS ASSOCIATED WITH THIS REMEDIAL ACTION.

PERFORMANCE STANDARDS OR GOALS; ALTHOUGH CURRENT BACKGROUND CONTAMINANT LEVELS ARE LESS THAN FEDERAL STANDARDS, FURTHER REMEDIATION WAS DEEMED NECESSARY TO PREVENT ADDITIONAL LEACHING OF CONTAMINANTS FROM THE SOIL TO THE GROUND WATER. EPA INTENDS TO RUN THE SOIL VAPOR EXTRACTION SYSTEM UNTIL IT IS EFFECTIVELY NOT REMOVING ANY ADDITIONAL VOCS. EPA DOES NOT INTEND TO CONTINUE REMEDIATION FOR OU3 BEYOND SOIL VAPOR EXTRACTION SINCE IT IS KNOWN THAT THE CONTAMINANT LEVELS IN SOIL WILL BE BELOW LEVELS THAT ARE PROTECTIVE OF HUMAN HEALTH.
 
Remedy:  THIS OPERABLE UNIT IS THE FINAL ACTION OF THREE OPERABLE UNITS FOR THE SITE. THE FIRST OPERABLE UNIT ADDRESSED THE DRINKING WATER BY SELECTING AN ALTERNATE WATER SUPPLY. THE SECOND OPERABLE UNIT ADDRESSED REMEDIATION OF THE GROUND WATER. THIS OPERABLE UNIT ADDRESSES SOIL CONTAMINATION AT THE SITE.

THE SELECTED REMEDY INCLUDES THE FOLLOWING MAJOR COMPONENTS;
* SAMPLING THE CONTAMINATED AREA (AND SAMPLING TWO OTHER AREAS) TO BETTER DEFINE THE EXTENT OF THE CONTAMINATION.
* UTILIZATION OF SOIL VAPOR EXTRACTION TO REMOVE THE CONTAMINATION FROM THE SOIL.
* CONFIRMATION SAMPLING.
