Tremendous improvements in ground-water sampling methodologies and analytical technologies have made it possible to collect and analyze truly representative samples to detect increasingly lower levels of contaminants now in the sub-parts-per-billion range. Though these new methods produce more accurate and precise data and are less expensive, many companies and government agencies are reluctant to update their sampling protocols and regulations claiming the transition would be too costly.The Essential Handbook of Ground-Water Sampling clearly details the economic and scientific case for adopting these new methodologies. Citing examples of unnecessary expenditure due to the inaccuracy of out-dated techniques, the editors point out that the expense of making incorrect decisions based on poor quality samples clearly negates any savings that might be realized by using older, more inefficient, and effectively short-sighted, methods. Using numerous figures, tables, and references to recent research, the editors explain the efficiency of utilizing newer, more accurate, techniques that produce higher quality data. The text provides a detailed discussion of every aspect of ground-water sampling from the development of a sampling and analysis plan, through sample collection, pretreatment, handling, shipping, and analysis, to the documentation, interpretation, and presentation of ground-water quality data. Successful sampling events and accurate data provide a sound foundation for making important, potentially expensive decisions regarding site monitoring, risk assessment, remediation, and closure. Armed with the information presented in this handbook, environmental professionals will be able to make sound technological and economic decisions regarding the choice of sampling equipment, methodologies, and procedures to meet their site-specific objectives and ensure the success of their ground-water sampling programs.

Hands-On Water/Wastewater Equipment Maintenance, Volumes 1 and 2 deals with equipment maintenance as individual components, not as complete machines, allowing more information about the design, application and maintenance requirements of machinery to be presented. This work-related inventory of wastewater covers plant components where breakdowns most frequently occur. The text explains the design, operation and maintenance of equipment critical to plant functioning; motors, pumps, blowers, mixers and more. The author demonstrates how careful attention to specific equipment parts and operation, especially through systematic maintenance, will lead to fewer breakdowns and more rapid repairs. These texts cover basic operating characteristics of machinery components, making them a valuable reference source as well as a training and maintenance manual.Written in easy-to-understand language, without complex formulas or technical theories, Hands-On Water/Wastewater Equipment Maintenance Volumes 1 and 2 provides you with basic information to help you acquire a general understanding of how components function and how to keep equipment operating properly. These two volumes belong in every water and wastewater treatment plant as a reference and manual for equipment maintenance. The hands-on approach provides maintenance operators, crew leaders and supervisors with practical information about how the machinery they work with every day functions, and how to keep it running smoothly.
