Based on the literature review, electrochemical precipitation and activated alumina adsorption were judged to be the most promising technologies for interim treatment of wastewater in Sump 1727. Sections of the report discuss the following: (1) Raw water characteristics; (2) proposed treatment levels for discharge to the RMA sanitary sewer; (3) treatability test methods that were used to evaluate the two technologies; (4) results of the tests; (5) selection of alumina as the preferred treatment; (6) conceptual design; and (7) costs. jg.

Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.

The objective of this task is to conduct a remedial investigation and feasibility study off-post of RMA. This RI/FS will: (1) evaluate the extent of contamination to the north and northwest of the arsenal, (2) estimate the risk to the environment and public health, (3) identify appropriate remedial responses. Sections of the report discuss the following: (1) geotechnical and chemical analysis, (2) ground water sampling, (3) safety plan for field activities, (4) data management and evaluation of data, (5) ea methodology which will be required in order to determine the magnitude and probability of actual or potential harm to the public or the environment.
