Anyone who has spent time at an indoor swimming pool knows that distinctive smell — but it turns out that odor isn’t actually from chlorine itself. It comes from chloramines, which are chemical compounds that form when chlorine binds with body waste in the water.
Now, a high school swimmer from Minneapolis, Minnesota has developed a portable device designed to measure chloramine levels. The student’s invention could offer a practical new way to monitor the chemical environment inside indoor pool facilities.
