INFORMATION - Reprint of paper, "Subsidence and Its Control," by J. F. Poland. UNITED STATES DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY WASHINGTON, D.C. 20242 GW Branch June 19, 1973 Code: 4300 5016 GROUND WATER BRANCH TECHNICAL MEMORANDUM NO. 73.06 Subject: INFORMATION - Reprint of paper, "Subsidence and Its Control," by J. F. Poland. The subject paper, which was published as part of American Association of Petroleum Geologists Memoir 18, Underground Waste Management and Environmental Implications, is enclosed for the information of you and your staff. The paper describes known instances of subsidence and their causes. The report also describes in some detail the measurement and control of subsidence, and relates subsidence phenomena to deep-well waste disposal. Subsidence is likely to be a growing problem in parts of the country with increasing ground-water development and subsurface waste emplacement.
