Communication Contents: GAS RESEARCH INSTITUTE LETTER: THIS RECOMMENDATION CALLED FOR THE DEVELOPMENT OF IMPROVED ODORANTS AND ODORANT MEASUREMENT TECHNIQUES AND A BETTER UNDERSTANDING OF ODORANT ADSORPTON BY SOILS. A.G.A. INITIATED SUCH A STUDY WITH ARTHUR D. LITTLE, INC., IN 1975. THIS STUDY WAS CONTINUED AND ITS SCOPE EXPANDED UNDER GRI SPONSORSHIP AFTER GRI BECAME THE OFFICIAL R&D ARM OF THE GAS INDUSTRY. THE FOLLOWING IS A SUMMARY OF OUR RESULTS AND CONCLUSIONS TO DATE: THE PROPENSITIES OF GAS ODORANTS TO BE ABSORBED BY VARIOUS CLAYS AND TO REACT WITH PIPE WALL MATERIALS WERE THOROUGHLY INVESTIGATED. DYNAMIC LABORATORY METHODS WERE DEVELOPED FOR TESTING BOTH SOIL/ODORANT AND PIPE/ODORANT INTERACTIONS. WE FEEL THAT WITH THESE STUDIES, A.G.A. AND GRI HAVE COMPLIED WITH NTSB RECOMMENDATIONS NO. P-74-43 AND P-74-45.
