Both of those results mentioned in the abstract are really fascinating. I'm really curious why UV absorbance increased as leachates were released, and the chlorine consumption kind of makes me think that if I ever have a house with PEX, I will want to install a whole-house purification system to remove chlorine, or run copper to at least all drinking locations.
Although the sharkbites are also really, really handy to have in your copper water system - if only to have a handful of caps in case of line breaks ...
Manufactured (AKA mobile) homes are typically plumbed with PVC or PEX[0], and PEX is pretty popular for traditional (AKA site-built) houses as well[1].

I wouldn't trust sharkbite fittings for anything really permanent (inside a wall, etc) but they are super handy for quick repairs.
PVC, CPVC, and PEX are all commonly used in drinking water plumbing.
I can't offer a qualified view on irrigation or utility plumbing; not sure if PEX leachates are worse than PVC, etc.
I used to have that item on my agenda all the time ... and then I just started buying sharkbites and putting things together like Legos.
It's not a solution for every plumbing and irrigation task I have - I still do find myself using PVC solvent from time to time ... but long gone are the days when I had to connect two pipes that were sort of off axis from each other and out of plane and how in the world will I put together 3 45s and 2 22.5 elbows to somehow make that connection.
Get yourself a roll of PEX (Uponor is the nice stuff) and some sharkbites and these jobs get really easy ...
