Water ChemSultants is one of only a few water treatment companies throughout North America with the designation of a Certified Water Technologist (CWT). Why is this important? Because it lets you know that we are highly qualified to solve problems and create efficiencies with your water systems. The CWT exam is one of the most thorough and difficult trade certification exams in the market, with testing areas including engineering, microbiology, chemistry, metallurgy, regulatory compliance, and more, the result of which is a very low passage rate. The fact is, you need a company with documented certification that can consult with you about your systems, diagnose inefficiencies, and provide solutions customized to your specific operation.
