Chloramination of drinking water is not a new technology. Some water utilities have successfully used chloramines for over 40 years; other utilities have experienced problems including nitrification, stimulation of biological growth, an inability to maintain adequate chlorine residuals, and customer complaints about the taste and/or odor of the water. Today, many utilities are considering chloramines as a secondary disinfectant within their distribution system, primarily as an economical method to meet ever more stringent disinfection byproduct limits. The primary purpose of this project was to develop material that could be used as a concise and practical guidance manual for those responsible for chloramination at water works facilities. A survey was conducted by mail of 63 public water systems that use chloramines. Telephone interviews were used as a follow-up to clarify information and gain additional insight into daily operations. Thirteen utilities were selected for an in-depth on-site visit to establish today's best operating practice for chloramination. These results were compared against a review of the current pertinent literature. Finally, a user's guide was compiled for those implementing or using chloramines.

The International Space Station (ISS) is an unprecedented achievement in global human endeavors to conceive, plan, build, operate, and utilize a research platform in space. As we near completion of the ISS on-orbit assembly, including all Partner laboratories and elements, we now turn to the real multifaceted purpose of the ISS. We will use the ISS as a human-tended laboratory in low-Earth orbit to conduct multidiscipline research and technology development and as an outpost to conduct human exploration. The ISS is uniquely capable of unraveling the mysteries of life on Earth; from biomedical research, to material sciences, to technology advancement, to research on the effects of long-duration spaceflight on the human body. The ISS is the first step in exploration, from research and discovery, to international cooperation, to commercial development, and to exploring beyond low-Earth orbit. We look forward to sharing this booklet outlining our ISS research capabilities and potential as we usher in this new phase of on-orbit research.

Given the current climate of results-driven accountability, school-based professionals have a significant contribution to make in improving the impact of programs and initiatives through the application of program evaluation methods and tools to inform decision making within a multi-tier system of supports framework. And yet there is currently a dearth of practical resources dedicated to developing school psychologists' competencies in program evaluation. Advancing Evidence-Based Practice through Program Evaluation will meet the needs of school psychologists and other school-based professionals seeking to use program evaluation approaches to enhance data-based decision making and accountability at a program and systems-level. This practical guide provides the most cutting-edge evaluation frameworks, methods, and tools available, with particular emphasis on the rapidly-developing areas of implementation research, evidence-based professional learning, and innovative approaches to communicating evaluation findings. The book will support school professionals in daily practice by enhancing and extending their knowledge and skills in measurement, assessment, consultation for systems change and the use of evidence-based interventions for academic and social/behavioral concerns, with a focus on evaluating the implementation and outcomes of school-based programs. The book will also facilitate the professional development of those currently engaged in graduate preparation programs in education, educational leadership, school counseling, and school social work, as well as the university faculty who guide their professional preparation. Finally, school professionals may also use Advancing Evidence-Based Practice through Program Evaluation to develop their professional competencies in implementing new initiatives funded by grants with clear expectations for program evaluation.
