Ask HN: How to ensure your water is safe to drink?

I am trying to decide if using a water filter for the whole house would bring any benefits. Particularly health benefits.

I think is all about testing your water to make sure it is safe to drink. From what I have seen the area where I live (US, SC) is tested periodically to ensure it is safe to drink.

There is also the lead component. I do not have any lead pipes but I am thinking about getting a water test from a lab anyway.

Are you doing anything to ensure your water is safe to drink? What are you thoughts?

Thank you.
