Nitrate Shield is your whole-home defense against nitrate

multiple tank water softening system

You cannot taste, see, or smell it, but in drinking water, nitrate contamination poses a health risk to all ages.

Nitrate contamination is on the rise in Wisconsin’s wells, and it is a serious health risk. Exposure to high nitrate/nitrite is linked to many serious health issues, including rapid heart rate, nausea, headaches, and abdominal cramps. Some studies also suggest an increased risk of thyroid problems and some cancers. Learn More

Testing and treating your water is the only way to eliminate nitrates from tap water. TheWisconsin Department of Resources (WDNR)recommends private well users test for nitrate annually using a Wisconsin certified lab.

Introducing Nitrate Shield™ from U.S. Water

Nitrate Shield is the cutting-edge treatment technology from U.S. Water that will stop nitrate before it ever enters your home. Unlike “under-the-sink” systems, Nitrate Shield is a robust “whole home” system that works together with your water softening system to remove nitrates from your entire water system.

      • The system can easily be scaled for both residential and commercial needs
      • It uses the industry’s best material to thoroughly and consistently remove nitrate from your water
      • State of Wisconsin approved

How Does Nitrate Shield Work?


Nitrates can get into groundwater from many sources, including fertilizers, manure on the land, and liquid waste discharged from septic tanks. Natural bacteria in soil converts various forms of nitrogen into nitrate.


Rent our equipment hassle-free!

Our rental options cover all equipment, a trouble-free maintenance agreement, plus all filter media for the rental term.



Water Softening

Your water begins with softening, eliminating minerals for Nitrate Shield’s best performance. The twin tank system means no downtime in your water flow and consistent water quality.



Nitrate Shield

Water flows through the resin material within the tank. This material traps and removes nitrate from your water supply, ensuring cleaner and safer water for you and your family.



Injection System

The Precision Injection pH Balancing System injects the precise amount of neutralizer into the water stream regardless of the flow rate to maintains a consistent pH level.

The Wisconsin state-approved Nitrate Shield* is a highly effective treatment system that uses an ion exchange system to remove nitrates from your water system. Unlike a reverse osmosis system, Nitrate Shield is installed at the point of entry for a whole-home treatment solution.

*The specifications for this nitrate reduction system have been determined to comply with applicable state code and have been approved by the Wisconsin Dept. of Safety and Professional Services.
