Our recent water bill from the rural water district was sharply up (5-6 times usual) so I investigated and found the 2 inch supply line from the meter to our house (about 700 feet) leaks after 15 years of leak free service. I walked the route where it is buried and saw no surface wetting area so the dirt where the leak is must perk nicely. I shut off the water coming into the meter and connected the house to our well (a one minute job as house is set up to accommodate switching between the two sources.)
I can take my time fixing the leak.
Now for the "meat" of this post: The well water looks milky when filling a glass. It is air. Let the glass of water stand for a while and the tiny bubblers float to the top leaving the water nice and clear. I got a lot of air in the line when switching between sources (rural water district and well) and thought that was maybe the problem but over 2 weeks later water is still filled with little bubbles. 15 years ago this well fed another house and there was never any milky look. In the interim the well only fed water to a stock watering trough and never noticed it looking milky. The pipe from the well to the house is about a quarter mile long.
Anyway, I'm soliciting opinions on what could be causing the air in the well water.
