The Canter text appeals mainly to Civil Engineering students taking course work in environmental assessment practice or impact assessment, usually taught at the junior/senior level as a popular elective. Some chemical and environmental engineers take the course as well. The author has specifically beefed up and improved the chapters on biological, cultural, and socioeconomic environmental factors. The book continues to emphasize both production and assessment aspects of environmental factors, i.e., air, water, and noise, together with some interesting case studies. The latest governmental methodologies and Environmental Impact Studies have been included in this timely revision.
