In another neighborhood we had a home here in murphy, that had wells that went in around the early 80s. The water test did show some bacteria coming through. So we put in a UV filter and it eliminated the problem and gave us peace of mind that when a bloom did occur we remained protected. I did not write this article to sell UV filters nor do I have stock in the company :) but we have found that is worked for us and wanted to share our experience. We did not have bacteria in our water here in Five Forks but added  an UV filter inline anyway.

 

Here is what our systems looks like here in Five Forks. We had it installed by Christian Plumbing

You may not see how the lines run but it in installed after the filter. Which make sure that no turbid water goes through the UV filter reducing it impact to the bacteria.  Notice the numbers on the control box it is connected to. That tells me how many more days of UV bulb life I have left.
 
The UV bulb does need to be replaced after running for a years number of hours because it drops in efficiency over time. I find replacements on Amazon for my model and can do it myself.
 
This is an addition you can do yourself with a little plumbing skill but, in my case, I appreciated the help from a local plumber. The two critical things for me were that the plumbing was run correctly and the right size filter was chosen to allow for the proper flow of water. Costs to purchase and install one of these runs around $600. The cost for a replacement bulb ranges from $30-$80 depending on the unit you install.
 
We can talk more about bacteria in another blog but there is a great deal of information out on the web on this and well water.
