摘要:

ABSTRACTA digital computer program which simulates a limestone aquifer as a pipe network was written and compared with the Sinkhole Plain aquifer of west‐central Kentucky. Model 1, which considers the flow in the network to be laminar, yielded values of head, flow in the network, and discharge at the bounding streams which are in reasonably good agreement with field observations. The over‐all hydraulic conductivity of the aquifer appears to be about 5600 meinzers if the zone of active flow is 30 meters thick, but the northeastern portion of the aquifer probably has a higher transmissivity. The indicated location of the principal ground‐water divide agrees well with data derived from wells and from tracing underground‐water flows. A second model (Model 2) was constructed which considers flow in the network to be turbulent. Although this model yields values which differ from Model 1, the differences are too small to allow the mode of flow in the aquifer to be distinguished using observation

摘要:

ABSTRACTThe technique for gridding of random data developed by Newton (1973) is useful in ground‐water investigations. The method appears to have potential for both regional and local ground‐water studies.The method as applied to the Wainwright area of Alberta shows that total dissolved solids content in glacial drift and at several depths in the bedrock is related to both the thickness and nature of the drift and to nature of the bedrock. Total dissolved solids in the ground water in areas of thick and coarse‐grained drift are lower than in areas of thin and finer‐grained drift. The dissolved solids content of the bedrock is lower where the bedrock is of nonmarine origin and where the overlying drift is thick. In areas where the bedrock is of marine origin and the glacial drift thin the total dissolved solids content of the ground water tends

摘要:

ABSTRACTPractically all of the toxic chemical land disposal sites now in operation are equipped with only minimal and generally ineffectual monitoring systems, which seldom are capable of detecting even excessive surface‐water and ground‐water pollution from such sites. From monitoring data normally obtained, it is practically impossible to quantitatively evaluate the total toxic chemical buildup in contiguous soil, plant, and water environments or the vertical and horizontal migration patterns of pollutants through underlying earth materials. Monitoring facilities and procedures described in this paper are designed to provide that data required to effectively evaluate all of these parameters. These evaluations in turn should be most helpful in selecting the safest possible sites for hazardous waste disposal, and in developing ways and means to design, operate, and monitor such facilities that will assure minimal danger to public health from this particular waste disposal practice in the fut

摘要:

ABSTRACTTo aid in determining the direction of ground‐water flow after the effluent from the Lake George Village sewage treatment plant is discharged onto natural delta sand beds, resistivity studies were made in the soil (sand) in the vicinity of the recharge beds. Ground water having high dissolved solids is identified as producing lower resistivity readings. The sewage effluent has a higher dissolved solids content than the existing ground water in the area. The path of the recharged sewage effluent, as identified by lower resistivity readings, appears to flow in a northerly direction from the sewage treatment plant along Gage Road toward West Brook. Due to interferences, the resistivity studies could not show whether the high conductivity ground water flows into or under West Broo
