Most places treat their water with chlorine or chloramine. Way better than having amoebas but if you can afford a filter do so. Different municipalities treat water differently, look yours up or test to see what you need. I went from carbon filters for chloramine to RO after moving somewhere with worse water

You don’t want to know how much plastic you drank. Stop that, buy a filter for your tap. Your brand is probably better than Nestle but not much. https://www.uclahealth.org/news/article/truth-about-nanoplastics-bottled-water
