Invited Topical Speaker: John D. Hem, Water-Quality Studies Today and Tomorrow

Hem, John D. 05 May 1973 (has links)
From the Proceedings of the 1973 Meetings of the Arizona Section - American Water Resources Assn. and the Hydrology Section - Arizona Academy of Science - May 4-5, 1973, Tucson, Arizona / Development of better instruments for analysis and automation have greatly increased the available information on quality of water during the past decade. There remains a need for further research on relationships between dissolved material and the solids in contact with water in order to cope with existing or potential problems in water quality such as the extent to which lead from automobile exhausts may contaminate water supplies, or the safety of disposal of toxic wastes into deep saline aquifers.
