Bedrock can extend hundreds of meters below the surface of the Earth, toward the base of Earth's crust. And the silt is slowly settling and compacting because of gravity. Whatever the case, there is "a huge trend of sinking throughout Louisiana, making it the hotspot of the country in terms of this kind of phenomenon," said geologist Stephen Leatherman of Florida International University. Along parts of the coast, the ground is now under water, and some yards have become marshland. National Oceanic and Atmospheric Administration 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). differ from these maps. Because each place has its own unique set of bedrock characteristics, each bedrock map is designed to best describe the features recorded by the geologist in that map area.
