Both aquifers have seen extensive pumping increases since 1975. Natural resource geology. The Santa Rita Mountains and Tombstone Hills contain silver and lead formed by hydrothermal fluids in fractures, during the Laramide orogeny. Arizona is known as the Copper State because it produces two-thirds of US copper annually.
The Gila River ( / ˈhiːlə /; O'odham [Pima]: Keli Akimel or simply Akimel, Quechan: Haa Siʼil, Maricopa language: Xiil [4]) is a 649-mile-long (1,044 km) [2] tributary of the Colorado River flowing through New Mexico and Arizona in the United States. The river drains an arid watershed of nearly 60,000 square miles (160,000 km 2) that lies ...
The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).
Kirkwood–Cohansey Aquifer, is located under the Pine Barrens (New Jersey) of southern New Jersey, contains 17 trillion US gallons (64 km 3) of some of the purest water in the United States. Mahomet Aquifer supplies water to some 800,000 people in central Illinois and contains approximately four trillion US gallons (15 km 3) of water.
This is a list of Superfund sites in Arizona designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up ...
The Agua Fria River (Spanish for "cold water") is a 120-mile (190 km) long intermittent stream which flows generally south from 20 miles (32 km) east-northeast of Prescott in the U.S. state of Arizona. Prescott draws much of its municipal water supply from the upper Agua Fria watershed. [6] The Agua Fria runs through the Agua Fria National ...
Floridan aquifer. The Floridan aquifer system, composed of the Upper and Lower Floridan aquifers, is a sequence of Paleogene carbonate rock which spans an area of about 100,000 square miles (260,000 km 2) in the southeastern United States. It underlies the entire state of Florida and parts of Alabama, Georgia, Mississippi, and South Carolina.
An aquifer is an underground layer of water -bearing material, consisting of permeable or fractured rock, or of unconsolidated materials ( gravel, sand, or silt ). Aquifers vary greatly in their characteristics. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Related terms include aquitard, which ...
