A FULL-SCALE CALGON ADSORPTION UNIT WAS INSTALLED AT RMA AND BEGAN OPERATION IN JULY, 1978. THE PURPOSE OF THIS UNIT WAS TWO-FOLD: (1) INSURE OPERATION IN COMPLIANCE OF CEASE AND DESIST ORDERS ISSUED BY STATE OF COLORADO DEPT. OF HEALTH, APRIL 7, 1975 AND (2) EVALUATE THE APPLICABILITY OF GRANULAR ACTIVATED CARBON OVER A THREE YEAR PERIOD FOR POTENTIAL USE IN DESIGNING AN EXPANDED SYSTEM CAPABLE OF ELIMINATING THE FLOW OF RESTRICTED TRACE ORGANICS OFF OF THE ARSENAL. IT IS THE PURPOSE OF THIS REPORT TO REVIEW THE OPERATION OF THE ADSORPTION SYSTEM AND THE RESULTS OBTAINED IN LIGHT OF PREVIOUS TREATABILITY STUDIES PERFORMED BY CALGON CORP. AND RMA PERSONNEL IN CONJUNCTION WITH RECOMMENDATIONS PROPOSED IN THE FY 1979 TECHNICAL REVIEW AND IMPLEMENTED BY RMA. TO ASSIST RMA PERSONNEL IN DEFINING FUTURE DESIGN PARAMETERS, THE RESULTS OF A COMPUTER ANALYSIS ON ALL DATA OBTAINED TO DATE IS PRESENTED FOR EVALUATION. -BKA.
