About Environmental PE Exam Products

"I passed the Spring 2004 PE exam for environmental on the first attempt. I can honestly say that I could not have done it without your guidance and help. That goes for the EIT too!" -- Paul B. Olsen, PE

"I recently passed the Environmental Engineering PE test on my first attempt. Everyone else taking the test the day I took it was repeating. Your Reference Manual was a great help. Not only that, I knew where to come to get links to purchase my seal once I passed." --Brian Scott Aiken, PE

"The key to my passing the Environmental Exam [was] purchasing the Super Environmental Engineering PE Package and plowing through all the 101 solved problems and most of the reference manual problems. I used the advice from the FAQs about books to bring, and those let me easily answer 5-10 questions that studying wouldn't have. Thanks a bunch!" --William Monaco, PE

"I recently received news that I passed the Environmental PE. Your material was indispensable. Thanks for putting together such a comprehensive package. See you for the Civil Exam!" --Laura Watson, PE

"Without the Environmental Engineering Reference Manual, I don't know where I would have started studying. I am a mother with a part-time job and very little free time. With this book, I was able to set a review schedule and know I had covered all the important topics." --Kelley H., PE

"The Environmental Engineering Reference Manual is just plain excellent, from the inside cover with its conversion units to the very comprehensive index at the back." --Jeff Byran

"The Environmental Engineering Reference Manual was the only textbook/reference manual I opened during the exam It was very helpful for most of the exam questions and was easy to use." --Derek Brown
