The focus of this project was to determine whether the soil at an industrial facility was contaminated above background concentrations in Ontario, and whether there was an unacceptable level of risk to the health of humans and the environment. The sampling plan, analysis and data interpretation were developed using guiding documents from the Ministry of the Environment and Climate Change, the Canadian Council of the Ministers of the Environment, and the United States Environmental Protection Agency. An emphasis was placed upon quality control, and a rigorous protocol for sub-sampling, to produce representative sub-samples for analysis. The results revealed that the soil at the site was within the range of background values for Ontario, and there was not an unacceptable level of risk to the health of humans and the environment for the elements analyzed.

The United States Environmental Protection Agency (EPA) has labeled as “friable” those building materials that are likely to readily release fibers. Friable materials when dry, can easily be crumbled, pulverized, or reduced to powder using hand pressure. Other asbestos containing building materials (ACBM) where the asbestos fibers are in a matrix of cement or bituminous or resinous binders are considered non-friable. However, when subjected to sanding, grinding, cutting or other forms of abrasion, these non-friable materials are to be treated as friable asbestos material. There has been a hypothesis that all raw asbestos fibers are encapsulated in solvents and binders and are not released as individual fibers if the material is cut or abraded. Examination of a number of different types of non-friable materials under the SEM show that after cutting or abrasion, tuffs or bundles of fibers are evident on the surfaces of the materials. When these tuffs or bundles are examined, they are shown to contain asbestos fibers which are free from binder material. These free fibers may be released into the air upon further cutting or abrasion.

Technology transfer is an important activity within the ll.S. Environmental Protection Agency. Specific technology transfer programs such as the activities of the Center for Environmental Research Information, the Innovative and Alternative Technology Program, as well as the Small Community Outreach Program are used to encourage the utilization of cost-effective municipal pollution control technology. Case studies of three technologies including a plant operations diagnostic/remediation methodology, alternative sewer technologies and ultraviolet disinfection are presented. These case studies are presented retrospectively in the context of a generalized concept of how technology flows from science to utilization which was developed in a study by Allen (1977). Additional insights from this study are presented on the information gathering characteristics of engineers and scientists which may be useful in designing technology transfer programs. The recognition of the need for a technology or a deficiency in current practice are important stimuli other than technology transfer for accelerating the utilization of new technology.

Introduction: Extreme weather events such as dust storms are predicted to become more frequent as the global climate warms through the 21st century. Studies of Asian, Saharan, Arabian, and Australian dust storms have found associations with cardiovascular and total non-accidental mortality and hospitalizations for stroke. However, the only population-level epidemiological work on dust storms in the United States was focused on a single small metropolitan area (Spokane, WA), and it is uncertain whether its null results are representative of the country as a whole. Hypothesis: Dust storms in the United States are associated with daily cardiovascular mortality. Methods: Dust storm incidence data (N=141), including date and approximate location, as well as meteorological station observations, were taken from the U.S. National Weather Service. County-level mortality data for the years 1993-2005 were acquired from the National Center for Health Statistics. Ambient particulate matter monitor concentrations were obtained from the U.S. Environmental Protection Agency. Inference was performed used conditional logistic regression models under a case-crossover design while accounting for the nonlinear effect of temperature. Results: We found a 9.5% increase in cardiovascular mortality at a two-day lag (95% CI: [0.31%,19.5%], p = 0.042). The results were robust to adjusting for heat waves and ambient particulate matter concentrations. Analysis of storms occurring only on days with <0.1 inches of precipitation strengthened these results and in addition yielded a mean daily increase of 4.0% across lags 0-5 (95% CI: [0.07%,20.8%], p = 0.046). In Arizona, the U.S. state with the largest number of storms, we observed a 13.0% increase at a three-day lag (CI: [0.40%,27.1%], p = 0.043). Conclusions: Dust storms in the U.S. are associated with increases in lagged cardiovascular mortality. This has implications for the development of public health advisories and suggests that further public health interventions may be needed.

To prepare dried municipal sludge material for use by the fertilizer industry, Ocean County Utilities Authority, New Jersey needed a process to increase the size of their sludge particles to between 1 and 3 millimetres. Several processes were evaluated during the planning and design phases of the project. The most cost-effective and reliable process was pressure agglomeration by compaction with a roll press, followed by granulation and screening of the compacted material. This process was tested with a sample of the Authority's digested sludge, which had been dried in a laboratory-scale evaporator. Fullscale compaction and granulation test equipment was used at a laboratory in West Germany to confirm the feasibility of the process and to develop data for the design of the project. As a result of its “innovative” approach to sludge processing, the United States Environmental Protection Agency (EPA) qualified this $60 million project for special funding. The project is nearing construction completion and due to be commissioned in spring of 1990.

Triage and rescue of casualties from accidents involving hazardous materials is a challenge for many emergency medical services (EMS) personnel. With very toxic materials, the untrained and unprepared rescuer may become a victim. In addition, few hospitals in the United States have decontamination units attached to their emergency departments and emergency department personnel may become exposed if the casualty is not decontaminated. Many environmental cleanup teams, including the U.S. Environmental Protection Agency (EPA) team, are well trained in materials handling but are not immediately available when a hazardous materials spill with personal injuries occurs.

This chapter presents an overview of climate change law in the United States, given the global impact of its domestic and international climate change policies. It traces the evolution of US climate change policy under different presidents, and discusses emerging programs under the Clean Air Act (CAA). Under the CAA, the Environmental Protection Agency (EPA) issues emissions standards, and under the Energy Policy Conservation Act, the National Highway Traffic Safety Administration (NHTSA) issues Corporate Average Fuel Economy (CAFE) standards. The chapter also describes the protection of endangered species under the Endangered Species Act (ESA). The ESA directs the Fish and Wildlife Service to designate certain species as endangered or threatened; for marine species that task falls to the National Marine Fisheries Service.
