This book will help the reader expand further into chemical engineering and become a licensed professional engineer (PE), which can offer a tremendous boost to one’s career, as there are certain career opportunities available only to licensed engineers. Licensure demonstrates high standards of professionalism, knowledge, and ability.

Because of the work experience requirement, PE examinees have generally been out of school for some time.  This book summarizes the theoretical background of topics covered in the exam, which will help potential examinees refresh their memories on subjects they may not have been exposed to since their undergraduate classes.  Another advantage of using this book to prepare for the PE exam is that two or three "logical distractors" (answers that result from common mistakes) are included among the answer choices for each problem.  The solutions to the problems also explain why the logical distractors are incorrect.  Research has shown that this is an efficient teaching tool.  Thus, the inclusion of these logical distractors and their explanations will give individuals a better foundation in the subject matter in a shorter period of time.

Although this book is intended primarily to help engineers prepare for the PE environmental engineering examination, it will also be useful in undergraduate engineering courses that cover environmental engineering topics.
