Description/Abstract:
THIS REPORT IS A COMPREHENSIVE, DETAILED REVEW OF WHAT IS KNOWN CONCER NING MIGRATION OF RADIONUCLIDES IN GROUND WATER AT THE NEVADA TEST SIT E (NTS). A HISTORY OF NTS IS GIVEN, THE GEOLOGIC AND HYDROLOGIC SETTIN G IS DESCRIBED, AND THE AMOUNT OF RADIOACTIVITY DEPOSITED WITHIN AND N EAR THE MAIN AQUIFERS IS ESTIMATED. THE LABORATORY AND FIELD INVESTIGA TIONS INTO GENERAL PROCESSES RETARDING THE MOVEMENT OF RADIOACTIVITY F ROM THE SOURCE AND DISPERSING ITS CONCENTRATIONS ARE DESCRIBED, TOGETH ER WITH RESULTS OF PROGRAMS DESIGNED TO MONITOR THE SOURCE TERMS AND T HE MOVEMENT OF RADIOACTIVITY AT THE SITE. 1) INFORMATION CURRENTLY AVA ILABLE IS INSUFFICIENT TO STATE CATEGORICALLY THAT RADIOACTIVITY WILL NEVER BE CARRIED OFF THE NEVADA TEST SITE BY GROUND WATER MOVEMENT; 2) NONETHELESS, SUCH A MIGRATION AT LEVELS ABOVE THE MAXIMUM PERMISSIBLE CONCENTRATION TO EXISTING WELLS AND SPRINGS IS CONSIDERED UNLIKELY; 3 ) IF OFFSITE MIGRATION OCCURS, IT WILL PROBABLY BE FROM THE SOUTHWESTE RN MARGINS OF PAHUTE MESA, WHERE THERE IS ONLY A SMALL CHANCE OF CONTA MINATING EXISTING PUBLIC WATER SUPPLIES; 4) TRITIUM IS THE MOST MOBILE RADIONUCLIDE AND MAY BE THE ONLY LONG-LIVED ISOTOPE OF CONCERN; 5) PR EDICTIONS OF MIGRATION BOTH WITHIN AND WITHOUT NTS ARE HAMPERED BY A L ACK OF VALUES FOR FUNDAMENTAL PARAMETERS USED IN TRANSPORT CALCULATION S. RECOMMENDATIONS FOR FUTURE STUDIES TO MINIMIZE UNCERTAINTIES ARE DE SCRIBED AND GIVEN PRIORITY RATINGS.
