How to Treat Acid Well Water with Iron, Manganese and Odors

I sent you my water sample for testing and need to know how to treat our well water.  We get a lot of staining, some corrosion it looks like… and there are odors too, its bad. 

well water test results


Dear sir,

The test results are attached for your records.  The results are showing a low (acidic) pH as well as high amounts of iron & manganese which will contribute to staining, odors, and general ruining of plumbing fixtures and piping. 

One very effective, low maintenance option would be to implement Chlorination injection along with appropriate filtration as well as a Contact Tank.  The Contact Tank is required for mixing time with contaminants, this is explained further below.

How this application will work is the chlorine bleach is injected whenever the well is on, once injected the 40-gallon contact retention tank allows for enough contact time for the chlorine to react with the contaminants and fully oxidize for filtration. 

The filter media will work great with the bleach and is used to further enhance performance. The chlorine can be set low so there is little or no chlorine tastes or odors after the iron filter.   However, you can also install a carbon filter as a final filter to remove all traces of chlorine if desired.

A Neutralizer will increase the pH levels so as to stop any corrosion from occurring as well as protecting the Iron filter medium from being ruined.  The end result being clean, non-staining, odor-free water throughout the home.

These Precision-24 Metering Pump systems are easy to install by anyone familiar with basic plumbing and very easy to maintain yourself.  Check out the diagram below:


Greensand is a proven media to remove iron, manganese and sulfur odors.  Iron and manganese are oxidized and precipitated instantly by contact with the Greensand media once the water has been injected with Chlorine.  No need for other costly chemicals or other complicated aeration applications. 

The following will show images, product links for additional information, as well as pricing on the recommended components.  Note we do offer combination discounts based upon the order placed.
