It is not E. coli that test was negative.. and yes the well is on a farm cows have been on the property for 100 years. So this is my likely source.. thinking I’ll go with the UV light just to be safe. Guy quoted me 850 to install and said maintenance of changing the bulb once a year is about 175 dollars

That's good.

Do you have hard or soft water where you live? The main thing to worry about with the UV lights is calcium or other mineral deposits on them reducing their effectiveness. That's more of a problem in hard water areas than soft water areas. You might be able to get away with a longer than 1 year life span on the bulb.
