Book Description
Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources.The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies.The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.

Book Description
Estimates of water withdrawals enable the depiction of trends in total water use for the Nation among different geographic areas, categories of use, and sources over time. Water-use information is a critical component of water budgets, which are essential to surface- water and groundwater availability studies. This information is also essential to accurately understand how future water demands will be met while maintaining adequate water quality and quantities for human and ecosystem needs across the United States of America. Data is represented in text abstracts and analysis, tables, chart graphics, and photos presented throughout. The estimates contained within this volume focus on water use for eight (8) categories: Public Supply * Irrigation Self-supplied Domestic * Livestock Aquaculture * Industrial Mining * Thermoelectric Power Related products: Other products produced by the U.S. Geological Survey (USGS) are available here: https://bookstore.gpo.gov/agency/us-geological-survey-usgs Check out our Water Management resources collection here: https://bookstore.gpo.gov/catalog/water-management

Book Description
The U.S. Geological Survey (USGS) established the National Water Quality Assesment (NAWQA) program in 1985 to assess water quality conditions and trends in representative river basins and aquifers across the United States. With this report, the NRC's Water Science and Technology Board has provided advice to USGS regarding NAWQA five separate times as the program evolved from an unfunded concept to a mature and nationally-recognized program in 2002. This report assesses the program's development and representative accomplishments to date and makes recommendations on opportunities to improve NAWQA as it begins its second decade of nationwide monitoring.
