This book was released on 1987 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drinking water criteria for diisopropyl methylphosphonate (DIMP) for the protection of human health were calculated by the basic formula proposed by the US Environmental Protection Agency. The no-observable effect level (NOEL) was derived from the available toxicological data base for 90-day studies in the dog, rat, and mouse. It is recommended that the drinking water criterion for DIMP be set at 26.3 mg/L, based on an uncertainty factor for 100 and an extrapolation of the body weight of the dog being the most sensitive of the three animals evaluated. Keywords: Diisopropyl Methylphosphonate pollutant, Toxicity, Drinking water criteria.

This book was released on 2000-11-25 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diisopropyl Methylphosphonate (DIMP) is a groundwater contaminant at the U.S. Army's Rocky Mountain Arsenal in Colorado. DIMP is a by-product created from the manufacture and detoxification of the nerve agent GB which the arsenal produced from 1953 to 1957. For awhile the Army and the State of Colorado disagreed upon the appropriate drinking-water contaminant guideline for DIMP. A drinking-water guideline of 600 micrograms per liter was established by the U.S. Environmental Protection Agency (EPA) in 1989 but the State of Colorado promulgated a lower guideline of 8 micrograms per liter. The significant difference between the two suggested values arose from the fact that both sides used different studies to determine their values. Colorado used one-generation reproductive toxicity study in mink, whereas EPA used a subchronic toxicity study in dogs. To resolve the disagreement, a two-generation reproductive study in mink was conducted. The Army asked the National Research Council (NRC) to independently evaluate the 1997 study and re-evaluate the drinking-water guideline for DIMP. This task was assigned to the Committee on Toxicology, which established the Subcommittee on the Toxicity of Diisopropyl Methylphosphonate, a multidisciplinary group of experts. The subcommittee evaluated the two-generation reproductive study as well as other studies relevant to the task. Data on the use of mink as a predictive model in toxicology were also reviewed. Re-Evaluation of Drinking-Water Guidelines for Diisopropyl Methylphosphonate is the subcommittee's report which shows that neither party was corrected in their DIMP guidelines. The report includes the subcommittee's evaluation and recommendations concerning the topic.
Download or read book Drinking Water Health Advisory written by Welford C. Roberts and published by CRC Press. This book was released on 1992-06-16 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Environmental Protection Agency (U.S. EPA) Office of Water (OW) initiated the Health Advisory Program in 1978 to provide information and guidance to individuals or agencies concerned with potential risk from drinking water contaminants for which no national regulations currently exist. Since that time, over 100 Health Advisories (HAs) have been published in final form for inorganic, organic, and microbial contaminants. This volume contains HAs for munitions chemicals developed as part of a Memorandum of Understanding between the U.S. EPA and the Department of the Army. To develop each HA, the authors reviewed toxicological data for each chemical and presented the relevant studies to allow an evaluation of the data without continued reference to the primary documents. Each HA has undergone critical internal review by the OW Toxicology Review Panel, EPA program offices, the EPA Reference Dose (RfD) Committee, the EPA Carcinogen Risk Assessment and Verification Enterprise (CRAVE) Committee, and the Army Medical Department (for munitions chemicals only). Finally, the HAs were reviewed by an external panel of experts in toxicology and risk assessments. Drinking Water Health Advisory: Munitions will be an important reference document for all DOD/DOE hazardous waste sites, drinking water professionals, and academic libraries.

Download or read book Water Treatment Unit Processes written by David W. Hendricks and published by CRC Press. This book was released on 2018-10-03 with total page 1266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unit process approach, common in the field of chemical engineering, was introduced about 1962 to the field of environmental engineering. An understanding of unit processes is the foundation for continued learning and for designing treatment systems. The time is ripe for a new textbook that delineates the role of unit process principles in environmental engineering. Suitable for a two-semester course, Water Treatment Unit Processes: Physical and Chemical provides the grounding in the underlying principles of each unit process that students need in order to link theory to practice. Bridging the gap between scientific principles and engineering practice, the book covers approaches that are common to all unit processes as well as principles that characterize each unit process. Integrating theory into algorithms for practice, Professor Hendricks emphasizes the fundamentals, using simple explanations and avoiding models that are too complex mathematically, allowing students to assimilate principles without getting sidelined by excess calculations. Applications of unit processes principles are illustrated by example problems in each chapter. Student problems are provided at the end of each chapter; the solutions manual can be downloaded from the CRC Press Web site. Excel spreadsheets are integrated into the text as tables designated by a "CD" prefix. Certain spreadsheets illustrate the idea of "scenarios" that emphasize the idea that design solutions depend upon assumptions and the interactions between design variables. The spreadsheets can be downloaded from the CRC web site. The book has been designed so that each unit process topic is self-contained, with sidebars and examples throughout the text. Each chapter has subheadings, so that students can scan the pages and identify important topics with little effort. Problems, references, and a glossary are found at the end of each chapter. Most chapters contain downloadable Excel spreadsheets integrated into the text and appendices with additional information. Appendices at the end of the book provide useful reference material on various topics that support the text. This design allows students at different levels to easily navigate through the book and professors to assign pertinent sections in the order they prefer. The book gives your students an understanding of the broader aspects of one of the core areas of the environmental engineering curriculum and knowledge important for the design of treatment systems.
