STUDY OF MECHANICAL ENGINEERING FEATURES OF POLAR WATER SUPPLY
Abstract
Surface waters of the northwest Canadian Arctic and northern and central Alaska differ from those usually selected as water supplies in the continental United States by only one feature, that is, the possession of rather high pH values. This fact, together with the low temperatures of such waters, tends to reduce the efficiency of disinfection procedures using chlorine and its compounds, and presumably most other disinfecting agents that might be employed. Considerable silt may be present in the larger Arctic rivers during the warm months, necessitating coagulation and filtration if they are to be used as water supplies. Ground waters of the northwest Canadian Arctic are rather unsatisfactory as water supplies; those of northern Alaska appear to be somewhat better but not entirely satisfactory in all cases. Both the ground and surface waters of the Eastern Canadian region exhibit no features that distinguish them from, say, those of the Eastern United States and appear to offer no special difficulties with respect to treatment for water supply purposes.
