This page represents the activities of the American Institute of Professional Geologists in the South-East District IV of Texas. This District is geologically complex and contains abundant oil and gas resources, lignite, uranium and other natural resources. Such resources have allowed Texas to develop a diversified range of high-technology driven petrochemical and related industries as well as a sound agricultural base, both with environmental awareness and effective regulation.
District IV covers the south-eastern part of Texas, which includes Houston, the nerve center for the worldwide petroleum industry, and Beaumont, where the petroleum age dawned on 10:30 in the morning on January 10, 1901. The great American oil producer “roared in like a shot from a heavy cannon and spouted oil a hundred feet over the top of the wooden derrick from what the world would soon know as the Spindletop oil field.” The world began to change rapidly as this new source of energy, petrochemicals, and medicine gained the favor of American industry as well as in countries overseas.
Delta-system reservoirs dominate coastal plays of the south-eastern part of Texas. The porosity and permeability of these geologically young reservoirs are high, reflecting the unconsolidated condition of the sands of Eocene age. More than twelve fields have been identified to date.
For additional information on oil & gas and other resources and related environmental aspects of East Texas, see the Web site of the Houston Geological Society (here).
The northern part of this district has, over the past 20 years, also had an important role in lignite exploration and mining. Centered in North-East Texas but extending into parts of the South-East District, a number of companies are currently mining lignite. Production for 1996 was approximately 53 million tons. This makes Texas the 5th largest coal producer in the nation, The lignite is mined from the Wilcox Group (Paleocene-Eocene) and other Tertiary fluvial units.
In Texas, about 98% of all lignite mined is used for electric power generation. Approximately 27% of the electricity generated in Texas is from lignite. Texas imports 24% of its coal from several western states and is the largest consumer of coal in the nation, burning 93 to 94 million tons per year. According to the Bureau of Economic Geology of Texas, the demonstrated reserve base of surface mineable lignite is sufficient to fuel electric generation for at least 100 years. The mining industry in Texas is a mature and healthy industry, providing substantial economic support to the state’s economy.
Upper Eocene and Miocene fluvial sediments host Tertiary-age “roll-front” uranium deposits in south Texas, which may extend into southeast Texas. Uranium mining (both open pit and in-situ mining) and yellow-cake production were initiated in the 1970’s and have continued sporadically since then.
Geopressured geothermal resources were identified in the 1970’s and attempts at development and commercialization were attempted with only limited success. This resource awaits development.
In a population of rapid growth, nearly full employment, and a free economy, Texas residents debate the age-old conflict between industrial development and the status quo, resource utilization and appropropriate management, and associated environmental issues. But population growth and economic development, coupled with a climate in which surface-water resources are scarce, have imposed real and potential water-supply problems in many areas of Texas. In much of Texas, available surface storage capacity in existing reservoirs will barely be sufficient to meet water demands of continued industrialization and urban development, especially during critical droughts which are common occurrences over the long term.
Extensive development of the readily available ground water has progressed rapidly over the past 20 years but has resulted in several problems, some local in nature, while others are more widespread. Problems of water quality, both from natural and man-made causes (e.g. nitrates), are expected to affect the suitability for use of water from portions of Texas’ aquifers in the future. Natural pollution, primarily sodium chloride, results from salt springs and salt flats within drainage areas of the basins. In some areas, this problem has been aggravated to some extent by oil and gas exploration and production activities. Mining has also been indicated as contributing to pollution. Balancing resources and local needs to maintain economic growth and development are the primary goals in Texas.
More than 50 percent of Texas in underlain by seven major aquifers and 16 minor aquifers. Because of industrial and urban development, long-term use of ground water is lowering water levels to the extent costs of production are increasing rapidly. Surface-water reservoirs are being developed in south-eastern Texas, and elsewhere, to offset the foreseeable problems of the future.
If a county does not appear on this list, it is because there is no state or federal Superfund site in that county. This index includes all sites – those where cleanup is complete as well as those for which cleanup or assessment is in progress (here).
On the county maps, a light blue star designates a federal Superfund site. A red star designates a state Superfund site.
