This book was released on 2004 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Safe Drinking Water Act (SDWA), established in 1974, is designed to protect the quality of drinking water in the United States. Congress amended the SDWA in 1996 to address the current source water problems and assist the United States Environmental Protection Agency (USEPA), state agencies, and local water utilities to plan for future drinking water quality challenges and assure the sustainable resource of safe drinking water. Specifically, Section 1453 of the 1996 SDWA amendments requires all states to establish Source Water Assessment Programs (SWAPs). This includes the submission of a plan to the USEPA detailing how the states will delineate source water assessment areas, inventory significant contaminants in these areas, and determine the susceptibility of each public water supply to contamination. ... The collection of existing data on chemical occurrence is one tool to help determine potential contaminants and perform susceptibility analyses for surface and groundwater. As a result, the American Water Works Association Research Foundation (AwwaRF) funded this research project to identify, list, and characterize chemical occurrence databases and data sets that can be used by states and utilities to perform source water assessments.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Water Quality and Purification, Four Volume Set provides a rich source of methods for analyzing water to assure its safety from natural and deliberate contaminants, including those that are added because of carelessness of human endeavors. Human development has great impact on water quality, and new contaminants are emerging every day. The issues of sampling for water analysis, regulatory considerations, and forensics in water quality and purity investigations are covered in detail. Microbial as well as chemical contaminations from inorganic compounds, radionuclides, volatile and semivolatile compounds, disinfectants, herbicides, and pharmaceuticals, including endocrine disruptors, are treated extensively. Researchers must be aware of all sources of contamination and know how to prescribe techniques for removing them from our water supply. Unlike other works published to date that concentrate on issues of water supply, water resource management, hydrology, and water use by industry, this work is more tightly focused on the monitoring and improvement of the quality of existing water supplies and the recovery of wastewater via new and standard separation techniques Using analytical chemistry methods, offers remediation advice on pollutants and contaminants in addition to providing the critical identification perspective The players in the global boom of water purification are numerous and varied. Having worked extensively in academia and industry, the Editor-in-Chief has been careful about constructing a work for a shared audience and cause

Download or read book Water Encyclopedia Domestic Municipal and Industrial Water Supply and Waste Disposal written by Jay H. Lehr and published by Wiley-Interscience. This book was released on 2005-06 with total page 1014 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 1 outlines water supply infrastructure. The requirements for supplying water to a home, a city or a factory can be very different. Experts in these fields explain the nuances of the details involved in maintaining adequate quantity and quality for these different consumers. Waste water management can be of even greater concern, yet its management can follow similar paths when compared to sophisticated water supply treatment. Both the physics and chemistry of these fields are fully covered. Volume 2 deals with the big picture of regional water supplies, how they become contaminated, how they can be protected and how they can best serve the surrounding populations and industries. Significant focus is placed upon the natural chemistry of available water supplies and its biological impacts. Case studies from regions around the world offer an excellent picture of the world's water resources.

Download or read book From Source Water to Drinking Water written by Institute of Medicine and published by National Academies Press. This book was released on 2004-11-01 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Institute of Medicine's Roundtable on Environmental Health Sciences, Research, and Medicine was established in 1988 as a mechanism for bringing the various stakeholders together to discuss environmental health issues in a neutral setting. The members of the Roundtable on Environmental Health Sciences, Research, and Medicine come from academia, industry, and government. Their perspectives range widely and represent the diverse viewpoints of researchers, federal officials, and consumers. They meet, discuss environmental health issues that are of mutual interest, and bring others together to discuss these issues as well. For example, they regularly convene workshops to help facilitate discussion of a particular topic. The Rountable's fifth national workshop entitled From Source Water to Drinking Water: Ongoing and Emerging Challenges for Public Health continued the theme established by previous Roundtable workshops, looking at rebuilding the unity of health and the environment. This workshop summary captures the discussions and presentations by the speakers and participants, who identified the areas in which additional research was needed, the processes by which changes could occur, and the gaps in our knowledge.

Download or read book Classifying Drinking Water Contaminants for Regulatory Consideration written by National Research Council and published by National Academies Press. This book was released on 2001-09-01 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Americans drink many gallons of tap water every day, but many of them question the safety of tap water every day as well. In fact, devices have been created to filter tap water directly before reaching cups. It's true; however, that the provision and management of safe drinking water throughout the United States have seen triumphs in public health since the beginning of the 20th century. Although, advances in water treatment, source water protection efforts, and the presence of local, state, and federal regulatory protection have developed over the years, water in the United States still contain chemical, microbiological, and other types of contaminants at detectable and at times harmful levels. This in addition to the growth of microbial pathogens that can resist traditional water treatment practices have led to the question: Where and how should the U.S. government focus its attention and limited resources to ensure safe drinking water supplies for the future? To deal with these issues the Safe Drinking Water Act (SDWA) Amendments of 1996 Safe included a request that the U.S. Environmental Protection Agency (EPA) publish a list of unregulated chemical and microbial contaminants and contaminant groups every five years that are or could pose risks in the drinking water of public water systems. The first list, called the Drinking Water Contaminant Candidate List (CCL), was published in March 1998. The main function of the CCL is to provide the basis for deciding whether to regulate at least five new contaminants from the CCL every five years. However, since additional research and monitoring need to be conducted for most of the contaminants on the 1998 CCL, the list is also used to prioritize these related activities. Classifying Drinking Water Contaminants for Regulatory Consideration is the third report by the Committee on Dinking Water Contaminants with the purpose of providing advice regarding the setting of priorities among drinking water contaminants in order to identify those contaminants that pose the greatest threats to public health. The committee is comprised of 14 volunteer experts in water treatment engineering, toxicology, public health, epidemiology, water and analytical chemistry, risk assessment, risk communication, public water system operations, and microbiology and is jointly overseen by the National Research Council's (NRC'S) Water Science and Technology Board and Board on Environmental Studies and Toxicology. In this report the committee needed to readdress its second report as well as explore the feasibility of developing and using mechanisms for identifying emerging microbial pathogens for research and regulatory activities. The promotion of public health remains the guiding principle of the committee's recommendations and conclusions in this report.

This book was released on 2023-03-10 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Available online: https://pub.norden.org/temanord2023-508/ This is a timely revision and update of the Nordic report on existing default values and recommendation for exposure assessments, from 2011. The report aims to give an updated overview of non-chemical-specific exposure factors to be used by the authorities during the process of assessing exposure to both adults and children, especially in risk assessment in relation to REACH. This contributes towards a further harmonization of such exposure factors to be used in exposure assessments. In the report the recommended values for the non-chemical specific exposure factors are represented. The focus of this report is to be used in the context of REACH, however, the recommended values can also be used in the broader context of chemical regulations.
