Well Water vs. Lake Water

I was talking about this with my dad over the weekend, and neither of us could understand why someone on a spring fed lake (which most lakes around our area are) would drill a well instead of going with a lake feed.

Other then the extra bit of filtration the ground would produce, is there a reason or justification for drilling a well vs. using a lake feed?
In the end, it's all the same water.

Depends on if you like feces and harmful bacteria and/or protozoa in your water or not, I suppose. Drinking water generally comes from deeper wells that do not have either. Even shallow wells need to be tested to determine their suitability as potable water.

Usually lake water gets run off that is full of pesticides, contain microbes, giardia and other water borne pathogens.

If you treat the water with a chlorination type system then I see no issue with it.

The well water is actually water that has been filtered by the earth. I believe 10 ft of soil is the min for cleansing. But I would need to find supporting data. I think I actually got that from septic leach field data.

When the effluent from the leach field enters the ground after 10 ft its supposed to be clean and can enter the ground water. This iis noted from septic design when a high water table is noted and you do not have the 10 ft soil min. a mound system typically is installed.

This all related to how ground water is purified.

My well is 30ft with 12 ft water height. Thats my saturation zone.

Hope this helps some.
