Stuck at house due to the coronavirus pandemic, individuals who discovered themselves sitting on financial savings from canceled holidays and different cutbacks constructed swimming pools in file numbers final year to make quarantine extra gratifying.
Then a fireplace on the finish of final summer season precipitated a shutdown on the plant that produces many of the nation’s provide of chlorine tablets. This year, the arrival of Memorial Day and pool season has trade consultants warning of a scarcity that threatens to disrupt yard plans from coast to coast.
“There is a very, very good possibility that we’re going to run out of chlorine tablets,” mentioned Rudy Stankowitz, a swimming pool marketing consultant and educator with greater than 30 years of expertise in the trade. “People should start looking into alternative methods of sanitizing swimming pools.”
The scarcity, which Mr. Stankowitz described considerably hyperbolically as a “poolocalypse,” will have an effect on residential swimming pools greater than public ones, which generally use totally different types of chlorine.
There are important public well being implications. Chlorine tablets are used to sanitize swimming pools and to maintain them freed from algae and micro organism. Inadequately sanitized water can turn out to be turbid, making it a security threat and a number one reason for drownings, Mr. Stankowitz mentioned.
“If somebody falls in, you might not see them, or they can get disoriented and not figure out how to get out,” he mentioned. “There’s even been cases where pools were green enough that they looked like a lawn.”
The chlorine scarcity has caught some new pool homeowners like Stephanie Winslow off guard.
Ms. Winslow was accustomed to spending scorching days along with her daughter and pals at an area public pool. When it closed due to the pandemic, she purchased an aboveground pool for the cattle farm the place she lives along with her household in Philippi, W.Va.
“We get a lot of use out of it,” Ms. Winslow, a web-based faculty monetary support specialist, mentioned. “We pretty much use it every day.”
This spring, Ms. Winslow purchased a month’s provide of chlorine tablets at Walmart for $26. After listening to in regards to the scarcity, she returned to purchase sufficient to final via the summer season, she mentioned, however there have been none obtainable at Walmart or Ace Hardware. On Amazon, a bucket of tablets — the identical dimension that had value her $26 per week earlier — was listed for practically $170.
“It’s just a shame that something that’s supposed to be really fun for people come summertime to enjoy now is almost a hassle because you don’t know if you’re going to be able to use it or not the whole summer,” she mentioned.
Others have fared higher. Nick Barboza, a current Air Force retiree, constructed a pool in his yard in San Antonio final May as a Mother’s Day present for his spouse, Julia. The buy was attainable, in half, as a result of the pandemic had pressured them to cancel their journeys to Chicago and Hawaii.
The pool “improved our family’s quality of life,” mentioned Mr. Barboza, whose youngsters are 6, 13 and 18.
“We use the pool in the summertime maybe six days a week,” he mentioned. “We’re always in the backyard just hanging out, and it kind of brought the family together when we were stuck in the house.”

The pool has a waterfall function and is fabricated from fiberglass, which requires much less chlorine and fewer different chemical substances. When he learn in regards to the chlorine scarcity in a Facebook group this year, Mr. Barboza purchased a 50-pound bucket of chlorine tablets from Sam’s Club — sufficient to final via the summer season.
Mr. Barboza’s pool was one in every of about 96,000 that have been constructed in the United States in 2020, a 23 % enhance over the earlier year, in accordance with a report on the chlorine scarcity that Goldman Sachs launched final month. The report, which is predicated on a survey of regional pool retailers, estimated that 110,000 new swimming pools can be constructed this year, essentially the most “in a single year since the Great Recession.”
In another report, the analysis agency IBISWorld attributed the expansion in pool development to “social-distancing guidelines and fears over the virus.”
The addition of so many new swimming pools may need been sufficient by itself to pressure the chlorine provide. But the actual hassle started in August, when a large fire broke out at a plant that’s simply west of Lake Charles, La., and that’s operated by Bio-Lab Inc., one of many nation’s largest producers of pool and spa merchandise.
The hearth, which occurred after the plant had already been broken by Hurricane Laura, burned for three days, releasing chlorine fuel into the air and halting the manufacturing of chlorine tablets. Bio-Lab advised the U.S. Chemical Safety and Hazard Investigation Board that about 835 tons of the tablets have been saved on the plant when the fireplace began. A spokesman for KIK Consumer Products, which owns Bio-Lab, declined to say how a lot of that was destroyed.
Trichlor chlorine tablets are used to sanitize about 70 % of the nation’s residential swimming pools, Mr. Stankowitz mentioned. He and different trade consultants mentioned that the Bio-Lab plant produced a majority of the nation’s provide of the tablets.
The ensuing scarcity was comparatively unnoticed till just lately, as swimming pools in Northern states started to open for the season and homeowners famous larger costs and buying limits at some shops.
Of the 26 pool-supply outlets that have been surveyed by Goldman Sachs, “15 expressed uncertainty or doubt when asked about whether they will have enough chlorine for pool season,” the report mentioned.
The spokesman for KIK Consumer Products mentioned the company was rebuilding the Bio-Lab plant. It could have 30 % extra manufacturing capability and shall be “well positioned to rapidly address the shortage” when it reopens subsequent year, he mentioned.
Chlorine tablets will not be the one approach to maintain a pool clear. Saltwater swimming pools, for instance, are geared up with a filtration system that makes use of electrical energy to generate chlorine, however retrofitting a pool might be prohibitively costly, Mr. Stankowitz mentioned. Less costly choices embrace including chemical substances like borate, which prevents algae, or liquid chlorine bleach.
To cut back the necessity for chlorine, the Pool and Hot Tub Alliance, an trade commerce group, advises folks to bathe earlier than swimming, to maintain pets out of the pool and to run the filter each day. It additionally recommends that individuals “shock” their swimming pools — including chemical substances that elevate the chlorine degree sufficient to kill algae and micro organism — with liquid chlorine, calcium hypochlorite or potassium monopersulfate as a substitute of chlorine tablets.
Above all, pool homeowners ought to resist the urge to panic-buy chlorine, Mr. Stankowitz mentioned. Doing so might threat making chlorine tablets as scarce as rest room paper was at first of the pandemic.
“If people start to hoard and people start to take in more supplies than they need,” he mentioned, “that’s only going to make the problem grow worse.”
