Course 1: Assessing Water Quality Problems (Instructor-Led Training)

WQA is pleased to offer a new instructor-led course, “Assessing Water Quality Problems.”  This 14-week course will be the first step towards both the Certified Water Specialist (CWS) and Certified Water Treatment Representative (CWR) titles. Certified Installers looking to take the next step towards the Certified Service Technician title and anyone interested in a deeper knowledge of applying treatment technologies will benefit from this course.

 Classes will be held live through Zoom for one hour a week plus an additional 30 minutes to one hour of homework each week. Two sessions are available to accommodate different time zones.

Instructor-led training offers two main advantages:

  1. It helps keep learners on track and progressing through the training
  2. It is better for those who learn by doing rather than reading

WQA instructors have real-world experience in POU/POE water treatment that they bring to the course. The course is structured to allow for discussion, questions, and sharing of ideas. Additional weeks may be scheduled to accommodate participants' questions.

Jason Chapman, President of Quality Water Solutions, explains the value of profesional certification in this video:
