Abstract:  THE 19-ACRE CRYOCHEM FACILITY IS A METAL FABRICATING FACILITY IN THE VILLAGE OF WORMAN, EARL TOWNSHIP, BERKS COUNTY, PENNSYLVANIA. THE FACILITY CONSISTS OF A WORKSHOP AREA, A WAREHOUSE, AND AN OFFICE BUILDING WHICH ARE ALL LOCATED IN THE SOUTHERN FOUR ACRES OF THE SITE. BETWEEN 1970 AND 1982, CRYOCHEM REPORTEDLY USED CHEMICAL SOLVENTS TO CLEAN DYE FROM METAL WELDS AT A RATE OF TWO TO THREE 55-GALLON DRUMS PER YEAR. THE FACILITY ALSO REPORTED THAT A SOLVENT SPILL HAD OCCURRED AT SOME UNSPECIFIED TIME IN THE PAST. SPILLED SOLVENT IS SUSPECTED TO HAVE COLLECTED IN THE WORKSHOP DRAINS AND FLOWED, THROUGH UNDERGROUND CHANNELS, TOWARDS A STREAM THAT FLOWS ACROSS THE SITE. SPILLED SOLVENT HAS ALSO MIGRATED THROUGH THE SOIL COLUMN AND HAS CONTAMINATED THE GROUND WATER UNDERLYING THE SITE. GROUND WATER SAMPLES, COLLECTED BETWEEN 1981 AND 1985 BY THE STATE AND EPA, REVEALED THAT AN ONSITE PRODUCTION WELL, NEARBY RESIDENTIAL WELLS, AND ONSITE SOIL HAVE BEEN CONTAMINATED. AS A RESULT OF DRINKING WATER CONTAMINATION, EPA INSTALLED ACTIVATED CARBON FILTERS IN 13 HOMES IN 1987. THIS RECORD OF DECISION, THE FIRST OF TWO OPERABLE UNITS, ADDRESSES THE DISTRIBUTION OF CLEAN WATER TO RESIDENTS WHOSE WATER SUPPLY IS AFFECTED OR POTENTIALLY AFFECTED BY GROUND WATER CONTAMINATION. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE GROUND WATER ARE VOCS INCLUDING TCA, DCA, TCE, DCE, AND PCE.

THE SELECTED REMEDIAL ACTION FOR THIS FIRST OPERABLE UNIT INCLUDES INSTALLATION OF DUAL-ACTIVATED CARBON ADSORPTION UNITS OR CONTINUED MAINTENANCE OF EXISTING CARBON UNITS AT AFFECTED HOMES UNTIL A PERMANENT CLEAN WATER SUPPLY IS DEVELOPED; IMPLEMENTATION OF PERIODIC SAMPLING AT POTENTIALLY AFFECTED HOMES; CONSTRUCTION OF A NEW UNCONTAMINATED WATER SUPPLY TO SERVE AFFECTED AND POTENTIALLY AFFECTED RESIDENCES AND BUSINESSES; AND PERIODIC SAMPLING OF RESIDENTS OUTSIDE THE AFFECTED AREA. THE ESTIMATED PRESENT WORTH COST FOR THIS REMEDIAL ACTION IS $1,260,000 WHICH INCLUDES ANNUAL O&M COSTS OF $80,000.
 
Remedy:  THIS OPERABLE UNIT IS THE FIRST OF TWO OPERABLE UNITS FOR THE SITE. THE OPERABLE UNIT WILL PROVIDE A CLEAN WATER SUPPLY FOR THE RESIDENTS WHOSE GROUND WATER HAS BEEN CONTAMINATED BY THE SITE.

THE MAJOR COMPONENTS OF THE SELECTED REMEDY INCLUDE;

1. CONTINUED OPERATION AND MAINTENANCE, UNTIL A PERMANENT CLEAN WATER SUPPLY IS DEVELOPED, OF DUAL ACTIVATED-CARBON UNITS INSTALLED AT 13 HOMES AFFECTED BY THE CRYOCHEM SITE.
2. INSTALLATION AND MAINTENANCE, UNTIL A PERMANENT CLEAN WATER SUPPLY IS DEVELOPED, OF DUAL ACTIVATED-CARBON UNITS AT HOMES AFFECTED BY CONTAMINATION FROM THE SITE THAT ARE NOT CURRENTLY EQUIPPED WITH CARBON UNITS.
3. PERIODIC CHEMICAL SAMPLING OF 13 CURRENTLY UNAFFECTED HOMES AND BUSINESSES WHICH COULD POTENTIALLY BE AFFECTED BY CONTAMINATION FROM THE SITE DUE TO THEIR LOCATION NEAR THE SITE.
4. INSTALLATION, OPERATION, AND MAINTENANCE OF DUAL ACTIVATED-CARBON UNITS AT RESIDENTIAL WELLS WHICH BECOME AFFECTED BY CONTAMINATION FROM THE CRYOCHEM SITE.
5. DEVELOPMENT AND CONSTRUCTION OF A NEW CLEAN WATER SUPPLY WELL AND DISTRIBUTION SYSTEM TO PROVIDE CLEAN WATER TO AFFECTED AND POTENTIALLY AFFECTED HOMES AND BUSINESSES. THE NEW WATER SUPPLY WELL WILL INCLUDE TREATMENT UNITS IF NECESSARY.
6. OPERATION OF A NEW CLEAN WATER SUPPLY WELL AND DISTRIBUTION SYSTEM TO PROVIDE CLEAN WATER TO AFFECTED HOMES AND BUSINESSES.

OPERABLE UNIT 2 WILL ADDRESS THE CONTAMINATION OF SOIL AND GROUND WATER AT THE SITE.
