While the water treatment certification exam has become increasingly difficult as government regulations have become more stringent, the study guides simply have not kept pace.
The Class D water treatment certification exam administered by AMP (Applied Management Professionals) has a failure rate of over 50%. The Class A certification exam has a failure rate of over 90% each month.
If you are preparing to take the exam, these stats aren't meant to scare you. This is to make you aware of the difficulty of the exam if you are not adequately prepared and to direct you to online resources on this and other websites that will help you be successful in passing the water treatment certification exam.
There are several areas that you will want to pay special attention to. Completely familiarize yourself with Maximum Contaminant Levels (MCL) as set by the Safe Drinking Water Act (SDWA). Also focus on water treatment math such as calculating volumes in a tank, calculating pressures based on hydraulic grades, calculating the overflow rate of a weir and various dosage calculations.
You will also need to know your way around a lab. Understand the procedures for testing for pH, chlorine residuals, alkalinity, iron and manganese, turbidity, fluoride, lead and copper and hardness.
Be sure to get plenty of rest the night before the certification exam. This is a long test and requires you to be mentally focused. When you go in for the exam you will only be allowed to have a simple calculator, a pencil and scratch paper. Some testing centers may supply these items. Be sure to check before arriving.
You will have three hours to answer 100 questions. Many of these questions can be answered quickly, but be careful. The wording of the questions is critical and one word can completely change the meaning of the question. Answer as quickly and thoroughly as you can so you will have more time to spend on the math problems. These will be your most time consuming questions.
Read each math question completely through two times. Often you will be given more information that you need to solve the problem. Determine what is being asked for and what information you need. After working the problem make sure you have the answer in the units required in the question.
Hopefully this site will help you as you study for the water treatment certification exam.
I am taking a D2 exam in September this year, so its my first time taking this test. I’ll take my time and hopefully that all be already at the end of the day.
Any succession for a first time taking this difficulty test and it’ll help me.
Thank a lot, Tailoni
Hi, I took the water treatment (T1) certification test and I passed it but I lost the letter with the test result. What can I do to get my certificate or a copy of result letter?
Thanks
I highly recommend using this water treatment exam prep course! Great job with the questions,answers, and testing format I purchased this course 24hrs before my state issued test, with such limited time I only had about 4hrs to crash study using this material. This site “Water Treatment Certification Exam” and a “Water Works” math book are the only study aid’s I used and was able to pass the CA T2 first try with a score of 86.
