Observations Of Water Hardness From Southwest Devon Island, Northwest Territories
SUMMARY Over the thaw period of 1970, the hardness in “Jason's Creek” increased systematically. Waters from other sources in the area, sampled in 1969 and 1970, show increases in hardness with distance of travel downslope, from large flows to small flows, and from flowing water to standing wate...
