We are on a well.  We are on the same underground system (the Floridan aquifer) that several bottled water companies draw from.  Deer Park Bottled Water has a huge facility about 60 miles east of here (Madison Blue Springs), they have another facility at White Spring which is 50 miles west of here in Liberty County.  They put the water straight into bottles, it is that pure.   The same water flows out of the faucets in my house.

It comes out of the tap when I turn it on!! 

Rain?

Very diverse  from well to  aquifer to the  Great Lakes and we had a wonderful  overall state system in all of our Cities  until our Governor  allowed Flint  Michigan to go toxic.  

Mostly high quality ground water, though some municipalities utilize lake and river water.

We have a water system that flows.

It's wet? (Not sure what you are getting at here)

All kinds.

My area is on well but different areas have different sources.

It varies from community to community and even within the same counties. In my area, some people are on public water, some are on private wells.  

In my province, we have many types of water systems.

We call it "Potomac Punch".

Trinity River Authority.

Hubby is from Brazil and freaks out when I drink straight from the tap. It's all I have ever known. He thinks I am crazy. But he married it.....

No state water system here.  I have a private well.  My county recently added water lines for county water in my area, but I'm keeping the well.  And my entire county doesn't have the lines, just some areas.

That's a complex question, given the size of California. There are two basic types - community water and private wells, but no doubt there are some other systems I am not aware of. We have a fair amount of recycled water for irrigation, and now in Carlsbad there is a desalination plant turning ocean water into drinking water for San Diego County residents

We have city/municipal water. When you get a little more rural in Nh it is all drilled wells. 

It varies by region.  

What I would consider polluted. It comes from various sources. 

We have a drought!  We buy our water from other states.

Water systems vary by municipalities in Florida.

my town has wells... our infrastructure is town water throughout the majority of the area....the country areas have individual wells on each property.... I have town water and town sewer....the best of both....

Diverse sources.  Our entire state is about diversity.  

We are mixed - public (distributed by cites), private (community) and wells (individual homes). There are many reservoirs in our area (CT and NY) that provide water to New York City - it's won many awards for taste and purity.

Chicago gets its water from Lake Michigan. Plenty of supply!

We do not have a state water system.

Global warming melts snow quicker. No water expect drought.

We have a wells in homes outside the cities.

There are no natural lakes in Maryland

Public Lake Michigan water.

I live one mile from Lake Erie and have a nursery stream running through my property.  (Nursery stream means no fishing as this is one of two streams that empty into Lake Erie that are used for stocking with various kinds of trout.). Other streams & rivers in western PA eventually dump into Ohio River.
