Welch for their comprehensive technical critiques of The authors wish to acknowledge the technical earlier versions of this report; to John A. Jones, W. On the gamma-ray log trace, deflections to the right higher values indicate finer-grained mudstones and deflections to the left lower values indicate coarser- grained sandstones Figure 5. In preparation for packer testing, the pump, column pipe, and all other equipment must be removed from the well. Tate, T.

    Iron, arsenic, and dolomite concentrations are all elevated in isolated conglomerate layers S. Detailed procedures for correct measurement of water levels using various methods are documented in U. Well-head concentrations, median values, and maximum contaminant levels for arsenic in the Norman well field, This change in chemistry is thought to reflect the influence of dissolution of sulfate-bearing rocks in the overlying Hennessey Group.

    All tests at Well 23 were conducted without a PVC access tube. Inthe maximum contaminant level for arsenic in drinking-water was lowered from 50 to 10 micrograms per liter. Table 2. Geological Survey USGS is to assess the quantity and quality of the earth resources of the Nation and to provide information that will assist resource managers and policymakers at Federal, State, and local levels in making sound decisions about the use of these resources. Ground water in the confined part of the aquifer mostly follows longer flowpaths on the order of miles to tens of miles before discharging to streams. This may be at odds with study objectives.

Well-maintenance logs indicate if the well has been or needs to be restored. Mann, Acknowledgments John S. If the location of the pump during testing is different from the location of the pump during production, though, the flow dynamics created during testing also can be different from the flow dynamics during production.

Well File and Field Folder A well file must be established for each existing well selected or new well installed for a water-quality study. DiBello, E. Pump A wireline-powered inflatable packer for borehole applications book and Access Points The type of A wireline-powered inflatable packer for borehole applications book installed in a supply well can affect the chemistry of a ground-water sample.

Spatial Variability of Water Quality in the Deep Aquifer System Because water chemistry changes along flow paths, the aquifer area can be divided into different water-type regions that are consistent with the Central Oklahoma aquifer conceptual model.

The temporal variability in well-head arsenic concentrations, from a compliance standpoint, can be problematic for a public water-supply system.

Using this research as a foundation, an investigation of individual well construction and dynamics was undertaken to determine if rehabilitation of water wells by well modification is possible. No sustained changes occur in well cross- sectional area either above or below the pump intake.

Results of pump intake relocation in Norman Well 36 49 Arsenic is a known carcinogen World Health Organization, Sample-collection point is located before water treatment, pressure tanks, or holding tanks, if ground-water quality assessment is a study objective.

Often, a column of oil can be found floating on the water column in a well equipped with an oil-lubricated pump. Turkowa, Boguslawa, and others,A single-well method for determining the direction and velocity of flow of underground waters--Results of in-the- field investigations: Nukleonika, v.

In general, flush-threaded rather than glued PVC casing is preferred. The purposes of the test hole were to 1 provide information on water quality with depth in an area of the aquifer that was relatively undeveloped and undisturbed prior to well completion and productionand 2 collect rock material for laboratory analysis of rock and water interactions outside the scope of this report for proposed future research involving in-situ arsenic remediation Figure 4.

This configuration reduces the possibility of damaging the tool or getting the tool lodged in the well. Faye, Larry J. The difference between the maximum and minimum detected concentrations, therefore, gives an indication of the range in water quality to expect if depth-dependent or zone-specific samples were collected.

Though the Garber Sandstone and Wellington Formation extend beyond the Central Oklahoma aquifer boundary, these units typically do not produce large quantities of water beyond the boundary.In the various methods of the present invention, reliance is placed on a first and second barrier 26 and 30 respectively positioned in a well 10 to provide well control during well suspension, completion and/or workover operations.

Each of the barriers is below the depth of the lowermost end of a completion string when that string is installed in the well Cited by: This section of the bibliography has publications.
