Soil color is often tied to a number of soil properties, such as organic matter, which make the soil dark in color, or iron oxides, which impart a rusty-reddish hue to the soil. Describes the geologic framework of the Mississippi River delta plain and the processes affecting its evolution and cultural history. Another key soil property is soil color. One is the topography of the bedrock surface. Large-scale development of ground-water resources with accompanying declines in ground-water levels and other effects of pumping has led to concerns, The pumpage of fresh ground water in the United States in 1995 was estimated to be approximately 77 billion gallons per day (Solley and others, 1998), which is about 8 percent of the estimated 1 trillion gallons per day of natural recharge to the Nation's ground-water systems (Nace, 1960). The most reliable method of obtaining the depth to the water table at any given time is to measure the water level in a shallow well with a tape. The USGS uses objective and reliable data, water-quality models, and systematic scientific studies to assess current water-quality, A series of groundwater technical procedures documents (GWPDs) has been released by the U.S. Geological Survey, Water-Resources Discipline, for general use by the public.

Suggest a dataset here. Soil salinity is another commonly measured chemical parameter. Unfavorable soil pH can be modified by applying acidifying fertilizers or lime. Using a book of standardized colored paint chips, soil scientists can establish the precise color of the soil by noting the hue, value and color saturation or chroma. These are types of soil parent material. Layers of impermeable material are both above and below the aquifer, causing it to be under pressure so that when the aquifer is penetrated by a well, the water will rise above the top of the aquifer. Rock formations, sometimes called geological or lithostratigraphic units, are sections of rock that share a common origin and range.Rock formations help geologists create geologic maps.
