Description/Abstract:
THE MOST LIKELY PATH FOR HYDROLOGIC TRANSPORT OF RADIONUCLIDES FROM TH E GASBUGGY SITE TO POSSIBLE WATER-USE POINTS IS THROUGH THE OJO ALAMO SANDSTONE. GROUNDWATER IN THE OJO ALAMO SANDSTONE FLOWS WESTWARD. THE POINT AT WHICH GROUNDWATER IN THE OJO ALAMO SANDSTONE COULD MIX WITH O THER WATER IS ALONG THE SAN JUAN RIVER NEAR THE MOUTH OF LOS PINOS RIV ER, 38 KILOMETERS NORTHWEST OF THE GASBUGGY SITE. BASED ON AVAILABLE D ATA, GROUNDWATER FLOWING FROM THE GASBUGGY SITE WILL TAKE 5900 YEARS T O REACH THE CONFLUENCE OF THE SAN JUAN AND LOS PINOS RIVERS. AT THE GA SBUGGY SITE, THE TOTAL DISSOLVED SOLIDS, SODIUM, AND SULFATE CONTENT O F THE GROUNDWATER OCCUR IN CONCENTRATIONS HIGHER THAN ACCEPTABLE FOR I RRIGATION OR DOMESTIC USE. TRITIUM, STRONTIUM-90, AND CESIUM-137 WILL DECAY TO CONCENTRATIONS BELOW THE APPROPRIATE CONCENTRATION GUIDES (CG ) FOR THE GENERAL PUBLIC BEFORE REACHING THE SAN JUAN RIVER. TRITIUM W ILL TRAVEL A MAXIMUM OF 2100 METERS IN NO MORE THAN 309 YEARS BEFORE D ECAYING TO A CONCENTRATION OF 1 X 10-3 MICROCI/ML (THE CG FOR TRITIUM) . BECAUSE OF THEIR HIGH KD VALUES, SR-90 AND CS-137 WILL MIGRATE NO FA RTHER FROM THE CAVITY THAN 320 METERS AND 3.5 METERS, RESPECTIVELY, IN 1,000 YEARS. BY THIS TIME, BOTH NUCLIDES WILL HAVE DECAYED TO WELL BEL OW THE CG.
