Summer 2021 could be another bummer as a chlorine shortage threatens to spoil swimming pool season in the US.
A surge in pool use last summer, due to people staying home during the coronavirus pandemic, has led to a scarcity of chlorine tablets this year.
The shortage was worsened by a chemical plant fire in August that devastated one of the country’s major suppliers.
The shortage is expected to drive prices up at least 60 percent and force pool cleaners to look for chlorine alternatives.
Swimming pools were originally kept clean through filtration systems and frequent changing of the water.
But that technique wasn’t extremely effective, allowing germs to proliferate.
