The Science of Environmental Pollution (3^rd Ed.)

This third edition has been updated throughout, and contains new information on endocrine disruptors in drinking water, contaminated sediments in surface waters, hydraulic fracturing wastewater, and more. Also, it will include new case studies, examples, and study questions.

Environmental issues continue to attract attention at all levels. Some sources say that pollution is the direct cause of climate change; others deny that the possibility even exists. This text sorts through the hyperbole, providing concepts and guidelines that not only aid in understanding the issues, but equip readers with the scientific rationale required to make informed decisions.
