摘要:

AbstractThe paper describes the main water‐well drilling systems used in the United Kingdom, with some details of the tools used and the principles of operation.Limitations as regards diameter and depth for various systems and their suitability for drilling different strata are discussed. The materials customarily employed for lining wells and for making sand screens are mentioned. The usual method of measuring the deflexion from the vertical is outlined.Methods of developing or improving the yields of wells, and inspections by television cameras are describe

摘要:

AbstractThere is a vital need for hydrologic data representing various environments that are free from the effects of man's activities. Without such data hydrologists will be stymied in distinguishing hydrologic changes caused by man from those caused by climate. To provide this background information, the U. S. Geological Survey is planning a nationwide hydrologic bench‐mark program in which runoff, transport of sediment, precipitation, changes in vegetation, fluctuations in ground water, and other hydrologic events will be studied in locales unaffected by the works of man. The knowledge gained in operating these bench marks will be invaluable in statistical appraisals of hydrologic data wherein a part of the record is affected by man's activitie

摘要:

AbstractThe power auger is a useful tool in the fields of ground‐water geology and hydrology. The Ohio Division of Water has had excellent success in utilizing this type of equipment during the past seven years. Augering is an economical and effective method of drilling test holes in unconsolidated deposits provided the tool is used within its limitations and where it works best. The augering method is particularly useful to the ground‐water investigator exploring sand and gravel aquifers or buried bedrock valleys, installing drive points, and making seismic refraction surv

摘要:

AbstractVast quantities of saline ground water await new commercial uses and economical demineralization processes for recognition as a valuable resource.Saline ground water is more widely distributed than any other natural resource, occurring throughout the United States and in geologic formations ranging from the oldest to the youngest.The Coastal Plain has the greatest reserve of fresh water in the country, but at depths ranging from a few feet to about 3,500 feet most of the fresh‐water aquifers also contain large quantities of brackish water. Paleozoic formations in the east‐central United States have long been producers of saline water as commercial brines and in association with oil and gas. The volume of saline ground water perhaps exceeds the fresh ground‐water supply in the Great Plains Region. The greater part of the Western Mountain Region is generally deficient in fresh ground water; however, saline water is present in highly permeable deposits in numerous closed basins and along saline streams. In each of these major ground‐water regions small to very large amounts of saline water can be pumped from wells ranging from a few tens of feet to several thousand feet in depth.Knowledge of saline water distribution is general and inadequate, having been attained as a by‐product of investigations of fresh‐water supplies. This knowledge should be expanded as technological advances in demineralization processes enhance the importance of saline water for potential supply in numerous water‐de

摘要:

AbstractTechniques in use of well‐point equipment for dewatering operations in Australia are described. Construction features of equipment used successfully in drying‐out trenches for pipelaying, excavation for underground structures, and dewatering base area for low‐level pumping stations are discussed. Typical layouts of well‐point equipment and typical pumping equipment features are given. Case histories of recent use of well‐point equipment are

摘要:

AbstractLocal government in Michigan, and perhaps in other states, must try to bring the best thinking there is concerning solutions to health problems which are within their legally designated area of responsibility. One such local health department activity in Michigan is the construction and operation of private individual water well systems. Monroe County, which is just beginning to feel the effects of the suburban spillover from Detroit, Michigan, and Toledo, Ohio, recognized, in 1961, the need for regulation of such water well systems. The subsequent development of a Code, and its enforcement have made us realize that we are just beginning to fully understand a subject which is much broader in scope from a public health standpoint than just construction details and bacterial tests.

摘要:

AbstractProfitable production of sodium sulphate from natural brine occurs only in California and Texas. Although the Ozark‐Mahoning Company developed sodium sulphate production from natural brine in the Monahans, Texas, area during the early 1930's, Pleistocene deposits in the “Rich Lake” and Brownfield depression areas of Terry County have recently been developed. The unusual geology of these deposits and production methods utilized are briefly desc
