If you're that concerned, you can get an whole house filter, an under-the-sink filtration system to filter just the kitchen tap, or you can just use a Brita pitcher. Or just buy bottled water by the 5-gallon.
If you want containers to haul and store water from a well, look on prepper and emergency storage websites like Shelf Reliance or Emergency Essentials. They have tons of products and tips.
