BTW, when you pull the water from the ground, what does the pulling? Do you have a pitcher pump? And unless you like it cold, what heats it? Do you have your own private hto spring? And when it goes into the ground do you really think your actions on the surface does not effect the aquifer? Water now has everything from herbicides and pesticides to prescription drug waste in it.
Sigh.. In answer to your questions, a 1/2 horsepower pump powered by electricity does the pulling. Isn't progress and technology wonderful? I heat it with a highly efficient gas water heater. When it goes into the ground, it very much becomes part of the ecosystem. It is PURIFIED by that ecosystem, and again becomes potable water. The energy to perform these modern miracles comes from the fair exchange of my efforts as a physician and as an engineer for commodities like gas, electricity, food, shelter, and the modern conveniences that human innovation and progress make available.
Where I went to medical school we had an abundance of fresh clear potable water - compliments of the desalination plant that the school installed on campus.
Your quoted reply, above, I'm pretty sure was aimed at me. That's ok. In the future, though, try not to be such an idiot.
