SEALING THE LAGOON LINING AT TREASURE ISLAND WITH SALT
FINE-TEXTURED EARTH MATERIALS, SUCH AS CLAY OR CLAYEY SAND AND GRAVEL, ARE POTENTIALLY IMPERVIOUS TO WATER. SOMETIMES, HOWEVER, EXPERIENCE IN THE USE OF SUCH MATERIAL FOR WATERTIGHT CONSTRUCTION HAS BEEN DISAPPOINTING. IN SOME CASES, CLAY MEMBRANES PLACED WITH THE GREATEST OF CARE HAVE BEEN FOUND TO BE SEMI-PERVIOUS AND HAVE FAILED TO PERFORM THE FUNCTION FOR WHICH THEY WERE DESIGNED. THIS PAPER DESCRIBES SUCH AN EXPERIENCE AT TREASURE ISLAND, THE SITE OF THE GOLDEN GATE INTERNATIONAL EXPOSITION IN SAN FRANCISCO BAY, CALIFORNIA, AND THE SIMPLE METHOD IN WHICH THE DEFECT WAS REMEDIED BY UTILIZING AN ELECTRO-CHEMICAL PHENOMENON OF COLLOIDAL CLAY. THE PAPER DESCRIBES THE NOVEL METHOD BY WHICH THE 10-IN. CLAY LINING OF THE BOTTOM OF THE SEVEN-ACRE FRESH-WATER LAGOON WAS SEALED BY A PRIMING OF SALT WATER PUMPED IN FROM THE BAY. THE LINING WAS COMPACTED BY USE OF A 14-TON FLAT ROLLER, BUT WITH COMPARATIVELY LOW AVERAGE DENSITY AND INCLUSION OF CONSIDERABLE AIR. INITIAL SEEPAGE LOSS FROM FRESH WATER IN A TEST POOL WAS 1.00 IN. PER DAY. THIS WAS REDUCED TO 0.10 IN. PER DAY BY THE SALT WATER TREATMENT DESCRIBED HEREIN. /AUTHOR/
