I want to be clear that I did not go to the YMCA outdoor pool opening on Saturday to make a scene. I went because Ember has been asking since Easter and because Tuck wanted to show a boy named Briggs that he can do a full underwater somersault now. I brought sunscreen, three towels, a cooler of cucumber water, and, in a small Altoids tin in the side pocket of my pool bag, eight pennies from 1994 because a woman named Lorrayne in my Facebook group Chlorine Cousins and the Truth About Public Water had told me what to do.
I dropped the first penny in the kiddie pool at 11:02 a.m. By 11:43 it was gone. Not faded. Not green. Gone. I have a time-lapse on my phone where you can watch it become a smaller penny, then a copper-colored idea of a penny, then a soft cloudy spot, then nothing, while a four-year-old in shark trunks paddles three feet away from it.
Lorrayne says you want a 1994 specifically because the alloy ratio after 1982 lets you read the chlorine more honestly than any test strip the county will sell you, and the strips at the front desk only go up to 5 ppm anyway, which she calls “the polite ceiling.” I do not know if Lorrayne has credentials. I know she has been right about the well water in Weaverville, the soft-serve machine at the Ingles on Smoky Park, and what they spray on the median grass before Memorial Day, so at this point I am not asking.
My sister-in-law Kasey, who works the front desk at a pediatric office in Hendersonville and is basically a nurse, says that when a public pool smells “like a pool” that is not chlorine, that is chlorine that has already done a job, and the job was a child. She says the actual chlorine smell is closer to a clean dinner plate. The YMCA on Saturday smelled like a CVS that had been on fire and then put out with a different CVS. A lifeguard named Caden told me the levels were “normal for opening weekend,” which is the kind of sentence a nineteen-year-old says when he has been handed a clipboard and a whistle and asked to defend an entire institution.
I want to be fair. Our backyard saltwater pool is also chlorinated — saltwater pools generate their own chlorine, which I learned the hard way from a man at Leslie’s who would not let me leave until I admitted it out loud — but salt is a mineral, the conversion is gentle, and I run it at the level a midwife in our birth circle described as “ocean-adjacent.” A penny in our pool from last August is still a penny. I checked. It is sitting in a little dish on the windowsill above my sink next to a piece of sea glass and a tooth.
My neighbor Britta brought her twins down to the YMCA around noon and I showed her the time-lapse on the deck chair and she did not say anything for a full thirty seconds, which for Britta is essentially a press release. She walked her twins back to the car still in their swim shirts. By two o’clock there were four moms I know personally sitting in a half-circle near the snack window comparing notes, and one of them, a doula named Pren, had brought her own pennies, which I want to say felt validating in a way I am still processing.
The Y issued a very nice email Sunday morning about “standard seasonal startup adjustments” and “shock treatment cycles,” which are words you use when you do not want to use the word that Lorrayne uses, which is “trichlor pucks the size of a hockey puck dropped in by a part-time pool tech named Garrett who also does the flowerbeds.” I am not naming Garrett to be cruel. I am naming him because the email did not.
Ember will be swimming in our backyard this summer. If your kiddo is at the Y this week, I am not telling you what to do. I am telling you that I have a tin of 1994 pennies and Pren has more, and any mother who wants one can text me, and we will figure out the rest from the deck chairs together.
