This volume describes the methods used in the surveillance of drinking water quality in the light of the special problems of small-community supplies, particularly in developing countries, and outlines the strategies necessary to ensure that surveillance is effective.

As water quality becomes a leading concern for people and ecosystems worldwide, it must be properly assessed in order to protect water resources for current and future generations. Water Quality Concepts, Sampling, and Analyses supplies practical information for planning, conducting, or evaluating water quality monitoring programs. It presents the

A timely, hands-on guide to environmental issues and regulatorystandards for the petroleum industry Environmental analysis and testing methods are an integral part ofany current and future refining activities. Today's petroleumrefining industry must be prepared to meet a growing number ofchallenges, both environmental and regulatory. Environmental Analysis and Technology for the Refining Industryfocuses on the analytical issues inherent in any environmentalmonitoring or cleanup program as they apply to today's petroleumindustry, not only during the refining process, but also duringrecovery operations, transport, storage, and utilization. Designedto help today's industry professionals identify test methods formonitoring and cleanup of petroleum-based pollutants, the bookprovides examples of the application of environmental regulationsto petroleum refining and petroleum products, as well as currentand proposed methods for the mitigation of environmental effectsand waste management. Part I introduces petroleum technology, refining, and products, andreviews the nomenclature used by refiners, environmentalscientists, and engineers. Part II discusses environmentaltechnology and analysis, and provides information on environmentalregulation and the impact of refining. Coverage includes: * In-depth descriptions of analyses related to gaseous emissions,liquid effluents, and solid waste * A checklist of relevant environmental regulations * Numerous real-world examples of the application of environmentalregulations to petroleum refining and petroleum products * An analysis of current and proposed methods of environmentalprotection and waste management

This manual suggests design operating and performance criteria for specific surface water quality conditions to provide the optimum protection from microbiological contaminants.

The term "emerging contaminants" and its multiple variants has come to refer to unregulated compounds discovered in the environment that are also found to represent a potential threat to human and ecological receptors. Such contaminants create unique and considerable challenges as the push to address them typically outpaces the understanding of their toxicity, their need for regulation, their occurrence, and techniques for treating the environmental media they affect. With these challenges in mind, this handbook serves as a primer regarding the topic of emerging contaminants, with current and practical information to help support the goal of protection where they are encountered. Features Explores the definition, identification, and life cycle of emerging contaminants. Reviews current information on sources, toxicology, regulation, and new tools for characterization and treatment of: 1,4-Dioxane (mature in its emerging contaminant life cycle) Per- and polyfluoroalkyl substances (PFASs; a newer group of emerging contaminant) Hexavalent chromium (former emerging contaminant with evolving science) 1,2,3-Trichloropropane (progressing in its emerging contaminant life cycle) Provides thoughts on opportunities in managing emerging contaminants to help balance uncertainty, compress life cycle, and optimize outcomes.
