Book Description
The revised edition of the guide to environmental impact of pharmaceuticals and personal care products The revised and updated second edition of Pharma-Ecology joins the health and environmental sciences professions' concern over the occurrence and fate of pharmaceutical and personal care products (PPCPs) in the environment and explores how to best minimize their impact. The text highlights the biological effects of various classes of pharmaceutical compounds under clinical settings, their modes of action, and approximate quantities consumed. The second edition contains the most recent knowledge about the ecological impact of PPCPs as more sensitive detection techniques have become available, since the book was first published. The second edition offers the most up-to-date information on pharma ecology and bridges the gap between medicine, public health, and environmental science. This new edition contains helpful learning objectives for each chapter, as well as a brief section at the end of each chapter that presents a set of open ended questions. This vital resource: • Explores the biological effects of pharmaceutical compounds under clinical settings, their modes of action, approximate quantities consumed • Provides researchers and scientists with critical background data on the environmental impacts of PPCPs • Contains the most current information on PPCPs' ecological impacts, based on new detection techniques • Bridges the gap between medicine, public health, and environmental science Written for ecologists, engineers, microbiologists, pharmacists, toxicologists, chemists, physicians, and veterinarians involved in pollution and environmental analysis, the second edition of Pharma-Ecology contains the most current information available on the environmental impact of pharmaceuticals and personal care products.

Book Description
Urban water and wastewater systems have an inherent vulnerability to both manmade and natural threats and disasters including droughts, earthquakes and terrorist attacks. It is well established that natural disasters including major storms, such as hurricanes and flooding, can effect water supply security and integrity. Earthquakes and terrorist attacks have many characteristics in common because they are almost impossible to predict and can cause major devastation and confusion. Terrorism is also a major threat to water security and recent attention has turned to the potential that these attacks have for disrupting urban water supplies. There is a need to introduce the related concept of Integrated Water Resources Management which emphasizes linkages between land-use change and hydrological systems, between ecosystems and human health, and between political and scientific aspects of water management. An expanded water security agenda should include a conceptual focus on vulnerability, risk, and resilience; an emphasis on threats, shocks, and tipping points; and a related emphasis on adaptive management given limited predictability. Internationally, concerns about water have often taken a different focus and there is also a growing awareness, including in the US, that water security should include issues related to quantity, climate change, and biodiversity impacts, in addition to terrorism. This presents contributions from a group of internationally recognized experts that attempt to address the four areas listed above and includes suggestions as to how to deal with related problems. It also addresses the new and potentially growing issue of cyber attacks against water and waste water infrastructure including descriptions of actual attacks, making it of interest to scholars and policy-makers concerned with protecting the water supply.

Book Description
This second edition demonstrates how chemistry influences the design of water treatment plants and how it should influence the design. Historically, water treatment plants have been designed from hydraulic considerations with little regard to chemical aspects. The many chemical reactions used for removal of pollutants from water simply cannot be forced to occur within current designs. This book re-examines this traditional approach in light of today's water quality and treatment. Will current water treatment processes be sufficient to meet future demands or will new processes have to be devised? Chemistry of Water Treatment assesses the chemical and physical efficacies of current processes to meet the demands of the Safe Drinking water Act, providing expert information to persons responsible for the production of potable water into the next century.

Book Description
Slow sand filtration is typically cited as being the first "engineered" process in drinking-water treatment. Proven modifications to the conventional slow sand filtration process, the awareness of induced biological activity in riverbank filtration systems, and the growth of oxidant-induced biological removals in more rapid-rate filters (e.g. biological activated carbon) demonstrate the renaissance of biofiltration as a treatment process that remains viable for both small, rural communities and major cities. Biofiltration is expected to become even more common in the future as efforts intensify to decrease the presence of disease-causing microorganisms and disinfection by-products in drinking water, to minimize microbial regrowth potential in distribution systems, and where operator skill levels are emphasized. Recent Progress in Slow Sand and Alternative Biofiltration Processes provides a state-of-the-art assessment on a variety of biofiltration systems from studies conducted around the world. The authors collectively represent a perspective from 23 countries and include academics, biofiltration system users, designers, and manufacturers. It provides an up-to-date perspective on the physical, chemical, biological, and operational factors affecting the performance of slow sand filtration (SSF), riverbank filtration (RBF), soil-aquifer treatment (SAT), and biological activated carbon (BAC) processes. The main themes are: comparable overviews of biofiltration systems; slow sand filtration process behavior, treatment performance and process developments; and alternative biofiltration process behaviors, treatment performances, and process developments.
