A comparison with municipal water should have been done alongside.

"Next, the researchers plan to look beyond bottled water to other potential sources of nanoplastics, including tap water."

Hopefully it will be sooner rather than later.

I imagine the results will be of no surprise to anyone - both sources contain an unacceptable level of some form of plastics.

Additionally, perhaps prompting better processing of all water source used for drinking, and potentially kill bottled water, or at the very least significantly reduce the cost of it - unless the industry manages to find some new spin for bottled water to justify its price and stay in the game.
