Population growth in Oregon, Washington, and Alaska is expected to increase demand for outdoor recreation on public land. This trend will be tempered by changes in the sociodemographic composition of the population. Among sociodemographic characteristics, different ages and incomes correspond to different participation rates. Although older Americans are participating more, participation is still lower among this group for active pursuits. Hence, as the population ages, demand for passive activities may increase. Low-income people participate at a much lower rate than higher income people in outdoor recreation, and the growing disparity between the wealthy and poor may create inequities in opportunities for participation. State recreation planning documents for Oregon, Washington, and Alaska have identified this issue as a significant concern for recreation providers. Another important factor in recreation trends in the region is ethnicity: different ethnic groups participate in outdoor recreation at different rates, exhibit some different preferences for specific activities, and use recreation sites in different ways. In Alaska, the number of Asian/Pacific Islanders is expected to quadruple by 2025; in Oregon, the Hispanic population may triple by 2025; and in Washington, both these segments of the population may double.

The Science of Water: Concepts and Applications, Fourth Edition, contains a wealth of scientific information and is based on real-world experience. Building on the third edition, this text applies the latest data and research in the field and addresses water contamination as a growing problem. The book material covers a wide range of water contaminants and the cause of these contaminants and considers their impact on surface water and groundwater sources. It also explores sustainability and the effects of human use, misuse, and reuse of freshwater and wastewater on the overall water supply. Provides Valuable Insight for Water/Wastewater Practitioners Designed to fill a gap in the available material about water, the book examines water reserve utilization and the role of policymakers involved in the decision-making process. The book provides practical knowledge that practitioners and operators must have in order to pass licensure/certification tests and keep up with relevant changes. It also updates all previous chapters, presents numerous example math problems, and provides information not covered in earlier editions. Features: Is updated throughout and adds new problems, tables, and figures Includes new coverage on persistent chemicals in drinking water and the latest techniques in converting treated wastewater to safe drinking water Provides updated information on pertinent regulations dealing with important aspects of water supply and treatment The Science of Water: Concepts and Applications, Fourth Edition, serves a varied audience—it can be utilized by water/wastewater practitioners, as well as students, lay personnel, regulators, technical experts, attorneys, business leaders, and concerned citizens.

Use of coastal, estuarine and freshwater recreational environments has significant benefits for health and well-being, including rest, relaxation, exercise, cultural and religious practices, and aesthetic pleasure, while also providing substantial local, regional and national economic benefits. These guidelines focus on water quality management for coastal and freshwater environments to protect public health. The guidelines: 1. describe the current state of knowledge about the possible adverse health impacts of various forms of water pollution; and2. set out recommendations for setting national health-based targets, conducting surveillance and risk assessments, putting in place systems to monitor and control risks, and providing timely advice to users on water safety.These guidelines are aimed at national and local authorities, and other entities with an obligation to exercise due diligence relating to the safety of recreational water sites. They may be implemented in conjunction with other measures for water safety (such as drowning prevention and sun exposure) and measures for environmental protection of recreational water use sites.

Water resources, both in terms of water quality and water quantity, are of critical importance in planning for sustainable development in Central Asia and the Caucasus, as well as in other parts of the world. This NATO Advanced Research Workshop (ARW), entitled "Risk Assessment as a Tool for Water Resources Decision-Making in Central Asia", was conducted on September 23-25, 2002 in Almaty, Kazakhstan. The ARW addressed methods and approaches by which risk assessment methodology that has been developed in the United States, Europe and elsewhere can be applied to environmental and water resource problems in Central Asia. The stated goals of the ARWwere: • to assess the existing state of knowledge in the context of potential applications of risk assessment tools to water resources and other environmental issues in Central Asia; • to identify research gaps and directions for future research in the area of water resources which may be addressed through the application of risk assessment tools; • to promote closer working relationships between the scientists and technical experts from Central Asia and the Caucasus, as well as the scientists and technical experts from the United States and Europe. Based on historical experiences of Central Asian scientists and their colleagues in other parts of the world, there is a demonstrated need in the region to provide education, training and technical assistance on environmental decision-making tools, including risk assessment.
