LABORATORY TESTS ON PHYSICAL PROPERTIES OF WATER BEARING MATERIALS

THE APPARATUS AND METHODS USED IN MAKING TESTS OF MECHANICAL COMPOSITION, POROSITY, MOISTURE EQUIVALENT, AND PERMEABILITY ARE DESCRIBED. THE SOIL SAMPLES TESTED FROM NEW JERSEY ARE ALL UNCONSOLIDATED SAND AND GRAVEL AND RANGE IN AGE FROM CRETACEOUS TO RECENT. THOSE FROM MONTANA COMPRISE UNCONSOLIDATED SAND, SILT, AND GRAVEL AND CONSOLIDATED ROCKS, CHIEFLY SANDSTONE AND SHALE, RANGING IN AGE FROM LOWER CRETACEOUS TO RECENT. THE SAMPLES FROM IDAHO ARE CHIEFLY SURFACE SILT AND THE LOESS THAT MANTLE CERTAIN RESERVOIR SITES. THE LABORATORY TESTS WERE CONDUCTED TO OBTAIN QUANTITATIVE DATA ON PERMEABILITY AND ON SPECIFIC YIELD. THE RESULTS OF MECHANICAL ANALYSIS AND TESTS OF POROSITY TOGETHER GIVE A NEARLY COMPLETE DEFINITION OF THE TEXTURE OF UNCONSOLIDATED MATERIAL, WHICH CHIEFLY CONTROLS BOTH THEIR PERMEABILITY AND SPECIFIC YIELD. THE POROSITY TEST SUPPLIES AN ESSENTIAL FACTOR IN CERTAIN INDIRECT METHODS OF OBTAINING BOTH PERMEABILITY AND SPECIFIC YIELD. THE MOISTURE EQUIVALENT GIVES AN APPROXIMATION OF THE SPECIFIC RETENTION AND OF THE SPECIFIC YIELD. THE PERMEABILITY TEST GIVES A DIRECT MEASUREMENT OF PERMEABILITY TO WATER. THESE TESTS GIVE FAIRLY RELIABLE COMPARATIVE DATA ON THE WATER-BEARING CHARACTERISTICS OF THE MATERIALS INVESTIGATED. AN OUTLINE IS PRESENTED OF WORK PERFORMED BY HAZEN, KING, AND SLICHTER ON THE EFFECTIVE SIZE IN RELATION TO PERMEABILITY.
