This book was released on 2002 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The N aquifer is the major source of water in the 5,400-square-mile area of Black Mesa in northeastern Arizona. Availability of water is an important issue in this area because of continued industrial and municipal use, a growing population, and precipitation of about 6 to 14 inches per year. The monitoring program in the Black Mesa area has been operating since 1971 and is designed to determine the long-term effects of ground-water withdrawals from the N aquifer for industrial and municipal uses. The monitoring program includes measurements of (1) ground-water pumping, (2) ground-water levels, (3) spring discharge, (4) surface-water discharge, and (5) ground-water chemistry. In 2001, total ground-water withdrawals were 7,680 acre-feet, industrial use was 4,530 acre-feet, and municipal use was 3,150 acre-feet. From 2000 to 2001, total withdrawals decreased by 1 percent, industrial use increased by 1 percent, and municipal use decreased by 3 percent. From 2001 to 2002, water levels declined in 5 of 14 wells in the unconfined part of the aquifer, and the median change was +0.2 foot. Water levels declined in 12 of 17 wells in the confined part of the aquifer, and the median change was -1.4 feet. From the prestress period (prior to 1965) to 2002, the median water-level change for 32 wells was -15.8 feet. Median water-level changes were -1.3 feet for 15 wells in the unconfined part of the aquifer and -31.7 feet for 17 wells in the confined part. Discharges were measured once in 2001 and once in 2002 at four springs. Discharges decreased by 26 percent and 66 percent at two springs, increased by 100 percent at one spring, and did not change at one spring. For the past 10 years, discharges from the four springs have fluctuated; however, an increasing or decreasing trend is not apparent.

The monitoring program includes measurements of (1) ground-water pumping, (2) ground-water levels, (3) spring discharge, (4) surface-water discharge, and (5) ground-water chemistry. In 1999, total ground-water withdrawals were 7,110 acre-feet, industrial use was 4,210 acre-feet, and municipal use was 2,900 acre-feet. From 1998 to 1999, total withdrawals increased by 0.7 percent, industrial use increased by 4 percent, and municipal use decreased by 4 percent. From 1998 to 1999, water levels declined in 11 of 15 wells in the unconfined part of the aquifer, and the median decline was 0.7 foot. Water levels declined in 14 of 16 wells in the confined part of the aquifer, and the median decline was 1.2 feet. From the prestress period (prior to 1965) to 1999, the median water-level decline in 31 wells was 10.6 feet. Median water-level changes were 0.0 foot for 15 wells in the unconfined part of the aquifer and -45.5 feet in 16 wells in the confined part. From 1998 to 1999, discharges were measured annually at four springs.

This book was released on 2003 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water-quality data are provided for six sites in Navajo National Monument in northeastern Arizona. These data describe the current water quality and provide baseline water-quality information for monitoring future trends. Water samples were collected from six sites near three ancient Indian ruins during September 2001 to August 2002. Two springs and one well are near Betatakin Ruin, one spring is near Keet Seel Ruin, and one spring and one stream are near Inscription House Ruin. Water from all the sites is from the N aquifer, a regional sandstone aquifer that is the source of drinking water for most members of the Navajo Nation and Hopi Tribe in northeastern Arizona. Concentrations of dissolved solids, major ions, trace elements, and uranium were low at the six sites. Dissolved-solids concentration ranged from 94 to 221 milligrams per liter. Concentrations of dissolved nitrate (as nitrogen) were generally low (less than 0.05 to 0.92 milligrams per liter) and were within the range of concentrations at other N-aquifer sites within 20 miles of the study area. Water samples from Inscription House Spring, Navajo Creek Tributary (near Inscription House Ruin), and Keet Seel Ruin Spring contained indicators of human or animal wastes-fecal coliform and Escherichia coli bacteria.

Download or read book Water Follies written by Robert Jerome Glennon and published by Island Press. This book was released on 2012-09-26 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Santa Cruz River that once flowed through Tucson, Arizona is today a sad mirage of a river. Except for brief periods following heavy rainfall, it is bone dry. The cottonwood and willow trees that once lined its banks have died, and the profusion of birds and wildlife recorded by early settlers are nowhere to be seen. The river is dead. What happened? Where did the water go. As Robert Glennon explains in Water Follies, what killed the Santa Cruz River -- and could devastate other surface waters across the United States -- was groundwater pumping. From 1940 to 2000, the volume of water drawn annually from underground aquifers in Tucson jumped more than six-fold, from 50,000 to 330,000 acre-feet per year. And Tucson is hardly an exception -- similar increases in groundwater pumping have occurred across the country and around the world. In a striking collection of stories that bring to life the human and natural consequences of our growing national thirst, Robert Glennon provides an occasionally wry and always fascinating account of groundwater pumping and the environmental problems it causes. Robert Glennon sketches the culture of water use in the United States, explaining how and why we are growing increasingly reliant on groundwater. He uses the examples of the Santa Cruz and San Pedro rivers in Arizona to illustrate the science of hydrology and the legal aspects of water use and conflicts. Following that, he offers a dozen stories -- ranging from Down East Maine to San Antonio's River Walk to Atlanta's burgeoning suburbs -- that clearly illustrate the array of problems caused by groundwater pumping. Each episode poses a conflict of values that reveals the complexity of how and why we use water. These poignant and sometimes perverse tales tell of human foibles including greed, stubbornness, and, especially, the unlimited human capacity to ignore reality. As Robert Glennon explores the folly of our actions and the laws governing them, he suggests common-sense legal and policy reforms that could help avert potentially catastrophic future effects. Water Follies, the first book to focus on the impact of groundwater pumping on the environment, brings this widespread but underappreciated problem to the attention of citizens and communities across America.
