Remedial Investigation Report. Volume 6. Southern Study Area, Final, Version 3.3


Book Description

The Southern Study Area (SSA) report integrates the study area history, geology, and hydrology with the results of soil, surface water, ground water, air, biota, and structures investigations to define the nature and extent of contamination in the southern portion of RMA. The SSA includes all of sections 11 and 12 and portions of sections 1, 2, 3, and 7. Historic reports indicate that the SSA was not used for the production of agents or pesticides, but was a disposal area and buffer zone. 904 soil samples were analyzed as were surface water samples and ground water samples from numerous wells. Organochlorine pesticides and HG are the most commonly detected contaminants. The volume of potentially contaminated soil is estimated at 1.51 million cubic yards. This report is presented in three sections: characterization of the study area - geology, hydrology, climate history.




Remedial Investigation Report. Volume 6: Southern Study Area, Sections 1.0, 2.0, and 3.0 Text, Version 3.3


Book Description

The purpose of the Southern Study Area (SSA) Report is to present the Army's Remedial Investigation (RI) results for the southern portion of Rocky Mountain Arsenal (RMA). This document is a formal RI product in accordance with the proposed Federal Facilities Agreement and Settlement Agreement (1988), the RMA Technical Program Plan (TPP) (PMO, 1988/RIC 88131R01), and the June 1985 U.S. Environmental Protection Agency (EPA) RI Guidance Document. The seven completed RI Study Area Reports (SARs), along with the RI media reports for air, biota, buildings, and water, fulfill the requirements of defining the nature and extent of contamination, and completing a comprehensive RI for the On-post Operable Unit of RMA as required by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the Superfund Amendments and Reauthorization Act (SARA), and the National Contingency Plan (NCP). The SSA report integrates known historical information, the results of previous investigations, and the current RI programs for buildings, soil, surface water, groundwater, biota, and air to present an overall environmental contamination assessment of the study area as required under Contract Numbers DAAA15-88-D- 0024. The SSA Report represents Volume VI of the overall RMA Remedial Investigation.
















Wildlife Ecotoxicology


Book Description

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.
