No, $32.00 is too much for a book. I’d like to know what he says about using swimming pool water, but not at that price.
Generally you shouldn’t drink swimming pool water but you can use it for cleaning and bathing until its too filled with algae.
Many of the chemicals used in pools contain things like copper. Which are bad for you.
I found this a while back:

Doulton are good too, Super Sterasyl and the Imperial Sterasyl.
They look alike, both brands made in UK, might be made by the same folks for all I know.
Biological filter with Sand, gravel and activated charcoal bucket setups made from 5 gal. Or 55 gal. Should be adequate to filter pool water for laundry, washing and irrigation.
Anyone with suggestions, please chime in.
Water is important! Duhh!
