WQA’s Instructor-Led Training
Foundation of POU/E Water Treatment
WQA’s introductory Instructor-led course on POU/POE Water Treatment is the first step toward the CWS/CWR/CST/CTD certifications. It walks the learner through identifying aesthetic problems, onsite testing, interpreting water analyses for aesthetic contaminants, and drinking water regulations.
Session – “Softener Design & Operation”
This session provides an in‑depth, practical look at how water softeners actually work—from ion exchange fundamentals and resin behavior to regeneration cycles, control strategies, and efficiency optimization. Participants will explore modern softener designs (including demand‑initiated and twin‑tank systems), salt selection, pretreatment requirements, and real‑world considerations such as septic system impacts and regulatory concerns. Ideal for professionals who want to strengthen their technical understanding and confidently design, install, and optimize softening systems.
Session A – 8 a.m. ET (7 a.m. CT)
Tuesday, Apr. 7
Session B – 12 p.m. ET (11 a.m. CT)
Thursday, Apr. 9
Application & Sizing of POU/POE Treatment for Drinking Water Contaminants
This course focuses on the occurrence, chemical behavior and treatment of contaminants that can be hazardous to health. It is the final course required for the CWS exam and the third of four for the CTD coursework.
Session – “Emerging Contaminants”
This session explores today’s most talked‑about drinking water concerns—including PFAS, pharmaceuticals and personal care products (PPCPs), endocrine‑disrupting chemicals, and microplastics—focusing on where they come from, how they behave in water, and what the science currently tells us about health risks. Participants will gain clarity on evolving regulations, sampling and testing challenges, and the real capabilities and limitations of treatment technologies such as activated carbon, ion exchange, membranes, and advanced oxidation.
Session A – noon ET (11 a.m. CT)
Tuesday, Apr. 7
Session B – 11 a.m. ET (10 a.m. CT)
Wednesday, Apr. 8
Application & Sizing of POU/POE Treatment for Aesthetic Contaminants/Foundation of POU/E Water Treatment
This course moves from identifying problems into how to select and correctly size treatment equipment for aesthetic contaminants. It is the final course in the CWR coursework and the second in a series for the CWS/CST/CTD titles.
Session – “RO Performance Factors & Sizing”
This session delivers a practical, application‑focused look at how membrane systems—especially reverse osmosis—perform in real‑world conditions. Participants will explore key factors that affect output and water quality, including pressure, temperature, osmotic pressure, TDS creep, and system recovery and efficiency. Through real manufacturer spec sheets and sizing examples, this open‑house class helps attendees build the confidence to properly evaluate, size, and optimize membrane systems.
Session A – 11 a.m. ET (10 a.m. CT)
Wednesday, Apr. 8
Session B – 8 a.m. ET (7 a.m. CT)
Thursday, Apr. 9
Installer Training
This course addresses best practices, treatment equipment operation, premise plumbing systems, safe drains, pressure loss, and installation procedures. Successfully completing this one course qualifies you to take the Certified Installers exam.
Session – “Backwashing Filters”
This session provides a comprehensive overview of backwashing filter systems, covering common filter types, media options, and the key considerations involved in proper system selection and design. Participants will explore neutralizing, carbon, multimedia, and oxidizing filters, with a focus on service flow versus backwash requirements, drain line sizing, system configuration, and startup and validation principles.
Session A – 8 a.m. ET (7 a.m. CT)
Tuesday, Apr. 7
Session B –10 a.m. ET (9 a.m. CT)
Thursday, Apr. 9
