Through multiple-choice questions, this guide tests at various levels the skills and knowledge required by laboratory analysts working at wastewater treatment plants. The guide contains more than 400 questions and answers, on 19 different topics, chosen to sample many aspects of an analyst's job. Each answer is accompanied by a page-specific reference to direct students to sources of additional information. Detailed solution sets are provided for answers requiring mathematical computation. The guide doubles as a valuable reference tool for laboratory analysts during examination preparation and on a day-to-day basis. It includes a list of the formulas used in a wastewater treatment plant laboratory including conversion factors and a detailed list of abbreviations and acronyms, a 220-term glossary, a comprehensive reference list, a table of elements, and tables of approved methods.

Cutting edge gas-shale corporate developers, environmental researchers, and concerned municipality representatives present contemporary technical information and explore potential issues and concerns with gas-shale stakeholders. The publication focuses on related science and engineering technology and presents information on emerging technologies, case studies, and rational cautions for chemical and radiological adverse human and environmental interactions. Includes Overview of gas-shale drilling and technology (Fracking 101) and management of water needs, reuse, and disposal. Overview of chemical aspects and significant considerations of shale-gas water management. Fate and transport of radium brought to the surface during drilling and other associated shale-gas operations. Relationship of shale formation properties, produced water quality, and water management strategies. The management of divalent metal scale formers (water softening) to enhance reuse of flowback water. In-process reuse and recycle of impaired shale-gas waters prior to disposal. Laboratory and field data linking conversion of bromides to bromate in conventional drinking water plant chlorination facilities. Reversible sorption and desorption of organics from impoundment basins and wells by an innovative organic-inorganic material based on silica. Case studies using nonconventional technology for treatment, reuse, and disposal of shale gas waters in Pennsylvania. Impoundment liner considerations for flowback water retention.
