ENV-167: Introduction to environmental engineering

Key themes in environmental science and engineering will be show-cased, with examples - from equator to the poles - including atmospheric processes and climate change, water quality, energy resources and urban development, with the amazing technologies use ...

Description

This lecture delves into the widespread dioxin pollution uncovered in Lausanne, Switzerland, raising concerns about health consequences, clean-up costs, and the extent of the problem. It explores the historical pollution carried out over several decades, the surprising findings in the city's drinking water, and the need for precautionary measures. The instructor discusses the challenges posed by legacy contamination, the industrial history of Switzerland, and the remediation technologies available. The lecture also covers the importance of investigating and cleaning up public sites, the potential for similar dioxin problems in other Swiss regions, and the government's draft revision of environmental protection laws.

Anders Meibom

Anders Meibom obtained his PhD in physics from the University of Southern Denmark in 1997. This was followed by two and a half years of PostDoc work at the Hawaii Institute for Geophysics and Planetology, where he conducted mineralogical studies of primitive chondritic meteorites. From 2000 to 2005, he was Research Associate in the Geological & Environmental Sciences, Stanford University, where he represented Stanford in the USGS-Stanford ion microprobe laboratory. In 2005, he became proifessor at the Muséum National dHistoire Naturelle in Paris. From 2006 to 2011 he was the director of the French national NanoSIMS laboratory. Since January 2012, he is professor at the EPFL in the School of Architecture, Civil and Environmental Engineering (ENAC). From April 2014, he is professor ad personam at the Institute of Earth Sciences, University of Lausanne.

Groundwater remediation

Groundwater remediation is the process that is used to treat polluted groundwater by removing the pollutants or converting them into harmless products. Groundwater is water present below the ground surface that saturates the pore space in the subsurface. Globally, between 25 per cent and 40 per cent of the world's drinking water is drawn from boreholes and dug wells. Groundwater is also used by farmers to irrigate crops and by industries to produce everyday goods.

Environmental remediation

Environmental remediation deals with the removal of pollution or contaminants from environmental media such as soil, groundwater, sediment, or surface water. Remedial action is generally subject to an array of regulatory requirements, and may also be based on assessments of human health and ecological risks where no legislative standards exist, or where standards are advisory. In the United States, the most comprehensive set of Preliminary Remediation Goals (PRGs) is from the Environmental Protection Agency (EPA) Regional Screening Levels (RSLs).

Bioremediation

Bioremediation broadly refers to any process wherein a biological system (typically bacteria, microalgae, fungi, and plants), living or dead, is employed for removing environmental pollutants from air, water, soil, flue gasses, industrial effluents etc., in natural or artificial settings. The natural ability of organisms to adsorb, accumulate, and degrade common and emerging pollutants has attracted the use of biological resources in treatment of contaminated environment.

Environmental law

Environmental laws are laws that protect the environment. Environmental law is the collection of laws, regulations, agreements and common law that governs how humans interact with their environment. This includes environmental regulations; laws governing management of natural resources, such as forests, minerals, or fisheries; and related topics such as environmental impact assessments.

Environmental protection

Environmental protection is the practice of protecting the natural environment by individuals, groups and governments. Its objectives are to conserve natural resources and the existing natural environment and, where it is possible, to repair damage and reverse trends. Due to the pressures of overconsumption, population growth and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that cause environmental degradation.
