“I enjoyed waterparks, but I didn’t really know the

Now, as technical manager of NSF’s recreational water
program, he understands quite a bit about pool systems and
“Early on I obviously didn’t know very much about the
industry,” Choe says. “However, there are a lot of
passionate people in the industry and they were willing to spend

reason Choe was enthusiastic about participating in the MAHC
project as chair of the Monitoring and Testing Technical Committee.
That group is reviewing and making recommendations on equipment for
monitoring and testing, including controllers and other
“The hope is that the final code will answer questions such
as ’How often should you test for different
attributes?’ and ’What types of different bacteria
should you test for?’” Choe notes.
In completing the project, he says the team used a
consensus-building process similar to the one used at NSF.
“Initially, we started with a ‘perfect world’
scenario; then we had to scale down and figure out what is
practical, critically central to public health,” he
Looking back, Choe has a firsthand understanding of the value of
“When I first came on board I had lots of questions and there
