Eight institutions participated in this program, giving analytical results of 9 major and 20 minor elements mainly by using ICP-AES for cations and IC for anions. Among the major elements, Na, Mg and Si showed coefficients of variation (CV) of 10% or more, whereas B, Al, Fe, Mn had coefficients less than 7%. The CV% of the minor elements Co, Cu, P, Cr, Pb was much greater (>30%) while the V analyses agreed well ( 2000 ppm) and SO 4  (>5000 ppm) gave considerable ranges (5.1 and 8.8 CV%, respectively) as did the obtained pH values (22 CV%). The measured  δ  18 O of the water samples and  δ  34 S of sulfate are in excellent agreement but the  δ D values had CV% of 8. Technical recommendations are presented to improve the analytical results for these elements with significant deviations from the mean values."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380285711829639170","@type":"Researcher","foaf:name":[{"@value":"B.
