YAY!!

You're Correct!

There are lots of things that can make groundwater unsafe to drink.

A. Leaky landfills.
Yes, imagine the goop from the dump mixing with groundwater and then gets into your glass of water? Yuck!

B. Underground storage tanks.
Yes, but only if a gas station or other business has a leaky tank underground. Then gas can get into the groundwater and maybe into your drinking water. Yuck!

C. Septic systems.
Yes, if they aren t working right they can contaminate your drinking water if you have a private well.
