An overview of the current state-of-understanding of perchlorate remediation is followed by a discussion of basic principles of microbial and abiotic processes, and of the engineering and implementation issues underlying the technologies described. Characterization of both anthropogenic and natural sources of perchlorate, including isotopic analysis to distinguish between differing sources, precedes discussions of the advantages, performance, and relative costs of applying a range of remedial technologies. Active, semi-passive, and passive in situ bioremediation are fully described and compared with emphasis on field application. Cost information for each technology, using case studies and analyses of several template sites, covers capital costs, as well as costs for laboratory testing, pilot-scale demonstration, design, system operation, monitoring and maintenance during operations, and demolition and restoration after remediation. In addition, analogous cost data are presented for pump-and-treat systems for each template site to illustrate the potential cost savings associated with the use of alternative approaches. Emerging technologies such as monitored natural attenuation, phytoremediation, and vadose zone bioremediation are described, and field demonstrations are used to illustrate the current stage of maturity and the potential applicability of these approaches for specific situations. Each chapter in this volume has been thoroughly reviewed for technical content by one or more experts in each subject area covered.

Every spring, the University of Massachusetts - Amherst welcomes all ''Soils Conference" Scientific Advisory Board members with open arms as we begin the planning process responsible for bringing you quality conferences year after year. With this "homecoming" of sorts comes the promise of reaching across the table and interacting with a wide spectrum of stakeholders, each of them bringing their unique perspective in support of a successful Conference in the fall. This year marks the 20 DEGREES DEGREES anniversary of what started as a couple of thoughtful scientists interested in developing partnerships that together could fuel the environmental cleanup dialogue. Since the passage of the Superfund Law, regulators, academia and industry have come to realize that models that depend exclusively on ''command and control" mandates as the operative underpinning limit our collective ability to bring hazardous waste sites to productive re-use. It is with this concern in mind that the Massachusetts Department of Environmental Protection privatized its cleanup program in 1993, spurring the close-out of over 20,000 sites and spills across the Commonwealth to date, in a manner that is both protective of human health and the environment while also flexible and responsive to varied site uses and redevelopment goals. So we gather together again, this year, to hear our collective stories and share success and challenges just as we share stories at a family gathering. Take a read through the stories contained in these proceedings.

FROM THE PREFACE Wastewater collection systems are dynamic, not static. There is no single maintenance method, equipment, or technique that works best. Keeping an open mind, trying new techniques and technologies benefits sewer system operators. No two collection systems are alike. Maintenance staffing, skill levels, equipment, budgets, age and complexity of the system make each agency unique. However, collection systems do have many traits and problems in common. Based on inventory and analysis, problems are identified. Defects may then be prioritized, and corrective maintenance operations put into effect. Preventive maintenance techniques can be applied to all collection systems. Preventive maintenance is cost-effective; it strives to prevent problems from occurring rather than reacting to difficult situations and "putting out fires." This book examines problems shared by all agencies: roots, grease, deterioration, hydraulic inefficiencies and structural defects. New solutions to age-old problems are applied: TV inspection and video interpretation, rehabilitation analysis and trenchless technologies. Computerized maintenance management and GIS softwares are discussed. Jetting, line cleaning and exciting developments in nozzle technology are included. Roots and chemical root control foam, wastewater control and grease are major topics as well. Wastewater Collection System Maintenance shares insights drawn from operator experience, trial and error, successes and failures in the field, interviews and years of research and studies. A user-friendly rating and evaluation system is explained and applied to field conditions. Equipment operation and maintenance, and "tricks of the trade" are also discussed. As cities grow, new systems are extended upstream from older sewers. Many of these core drainage basins are now under capacity and in need of capital improvement projects. There are approximately 600,000 miles of sanitary sewers in the country. Nationwide, there exists a huge backlog of sewer pipes that need rehabilitation. Replacement would cost many billions of dollars. Maintenance operators are entrusted with the care and feeding of an aging sewer infrastructure.

This text provides an account of the nature and applications of the Coliform Index. Since the beginning of the 20th century, indicator organisms, in particular the coliform group, have been used to ensure the microbial quality of drinking water. World-wide legislation to protect consumers is based on these out-dated and unreliable tests and while there is considerable concern among scientists over their use, the water industry and regulators continue to place near total reliance on the Coliform Index. This has serious implications for public health and necessitates the debate which this book enters.

Move past the "yuck factor" by learning the benefits and science behind recycling wastewater to beat climate change. In recent years, humans have begun to turn the age-old taboo against mixing sewage and drinking water on its head by using advanced treated wastewater to supplement a city's drinking water supply. This increasingly widespread practice, known as potable reuse, qualifies as nothing less than a drinking water revolution. Water reuse offers a renewable, locally managed, and drought resistant water supply. The Water Recycling Revolution tracks the story of this development, examines the pros and cons, and explores its future potential. In this book, William M. Alley and Rosemarie Alley answer our most pressing questions: How do you get people to overcome the visceral reaction known as the "Yuck Factor" and not only drink, but appreciate, recycled water? What about all those pharmaceuticals and personal care products that people casually flush down the drain? Will diverting discharges from a wastewater treatment plant damage downstream users or ecosystems that previously depended on that water? And what are the implications for climate change? These questions are answered by delving into the history of major water recycling projects from California to Virginia, each with a unique story of what led them to develop potable reuse, as well as the challenges they had to overcome. Additional concerns addressed include pathogens, contaminants of emerging concern, achieving acceptable risk, onsite and decentralized reuse systems, and direct potable reuse. Recycling wastewater can make for a bright future in the fight against climate change, and this book is a valuable resource to convince readers.

With the advent of the Safe Drinking Water Act Amendments of 1986, many water utilities are reexamining their water treatment practices. Upcoming new regulations on disinfection and on disinfection by-products, in particular, are the primary driving forces for the big interest in ozone. It appears that ozone, with its strong disinfection capabilities, and apparently lower levels of disinfection by-products (compared to other disinfectants), may be the oxidant/disinfectant of choice. Many utilities currently using chlorine for oxidation may need to switch due to chlorine by-product concerns. Utilities using chloramines may need to use ozone to meet CT requirements.
This book, prepared by 35 international experts, includes current technology on the design, operation, and control of the ozone process within a drinking water plant. It combines almost 100 years of European ozone design and operating experience with North American design/operations experience and the North American regulatory and utility operational environment. Topics covered include ozone chemistry, toxicology, design consideration, engineering aspects, design of retrofit systems, and the operation and economics of ozone technology. The book contains a "how to" section on ozone treatability studies, which explains what information can be learned using treatability studies, at what scale (bench, pilot, or demonstration plant), and how this information can be used to design full-scale systems. It also includes valuable tips regarding important operating practices, as well as guidance on retrofits and the unique issues involved with retrofitting the ozone process.
With ozone being one of the hottest areas of interest in drinking water, this book will prove essential to all water utilities, design engineers, regulators, and plant managers and supervisors.
