High Nitrates in Water: Causes, Testing & Treatment Options
What Are Nitrates in Water?
Nitrates (and nitrites) are compounds made of nitrogen and oxygen that can be found in groundwater and well water. While low levels may occur naturally, high nitrate levels in water can pose health risks.
Nitrates are colorless, odorless, and tasteless. Because of this, many people do not realize they have a problem until they schedule a water test. High nitrate levels are especially common in agricultural areas.
In Iowa and Nebraska, nitrates have become a big concern for people who depend on private well water. In fact, in 2025, the Central Iowa Water Works issued a ban on watering lawns as almost record-high nitrate concentrations in the Des Moines and Raccoon rivers risked exceeding the utility’s ability to treat and manage the water supply. This ban affected about 600,000 commercial and residential customers.

What Causes Nitrates in Water?
Several factors can lead to high levels of nitrate in water, including:
- Fertilizer runoff from farms and lawns
- Septic system leaks
- Animal waste
- Decaying organic matter
- Flooding or heavy rainfall
- Shallow or aging wells
As water moves through soil, nitrates can enter underground water supplies and contaminate private wells.
Why Are Nitrates in Drinking Water a Concern?
High nitrates in water may create health concerns, especially for infants under six months old. Nitrate exposure can reduce the blood’s ability to carry oxygen. This condition is sometimes called “blue baby syndrome” and can be deadly without treatment. Pregnant women and people with certain health conditions should also avoid drinking water with high nitrate levels.
Because nitrates cannot be seen, smelled, or tasted, routine water testing is important for homes with well water. A professional nitrate water test can help determine whether levels are elevated and whether treatment is needed.
Signs You Should Schedule a Water Analysis
Roughly 1 in 5 Americans may face potentially dangerous nitrate concentrations in their tap water. It’s important to test your water for nitrates if:
- Your home uses well water
- You live near farmland or agricultural areas
- Your well is older or shallow
- Nearby homes use septic systems
- Your area recently experienced flooding
- You have never had your water tested
The EPA recommends annual well water testing for nitrates and other contaminants. Futuramic’s Clean Water Center offers professional lab testing to help homeowners identify water quality problems quickly.
How To Remove Nitrates From Water
Many homeowners ask, “How do you get rid of nitrates in water?” One of the most effective solutions is a reverse osmosis (RO) system. A reverse osmosis water filter uses a specialized membrane to reduce dissolved contaminants in drinking water. Reverse osmosis systems are commonly installed at the kitchen sink to provide cleaner drinking and cooking water.
Why Reverse Osmosis Is One of the Best Nitrate Water Filtration Systems
Reverse osmosis systems are widely recommended for nitrate water treatment because they can effectively reduce nitrate levels at the tap. RO uses a semipermeable membrane that rejects many dissolved contaminants, including nitrates.
Benefits of Reverse Osmosis Water Filters for Nitrates
A reverse osmosis system can help:
- Reduce nitrates in water
- Reduce other dissolved contaminants like fluoride, salts, and heavy metals
- Improve the taste of drinking water
- Provide cleaner water for cooking
- Deliver purified drinking water directly from the faucet
Many homeowners pair reverse osmosis with additional water treatment systems to improve overall water quality throughout the home.
We Help You Choose the Right Water Treatment System for Nitrates
Not all filtration systems are designed to remove nitrates. Standard sediment or carbon filters may not adequately reduce nitrate levels. At Futuramic’s Clean Water Center, we help homeowners choose filtration systems based on their water test results and household needs.
We provide:
- Nitrate water testing
- Professional system recommendations and installation
- System maintenance, including filter replacement and RO membrane replacement
- System repairs when needed
Nitrate Water Treatment for Iowa Homes
Nitrates in water in Iowa are a rising issue due to agricultural activity and groundwater conditions. Homes with private wells may face a higher risk of nitrate contamination, especially in rural areas.
Routine testing and proper treatment can help improve drinking water quality and reduce nitrate exposure. Futuramic’s Clean Water Center offers expert laboratory testing and water treatment services across Western Iowa.

FAQs About Nitrates in Water
-
How do nitrates get into well water?
Nitrates can enter well water through fertilizer runoff, animal waste, septic system leaks, decaying organic matter, and flooding. Homes located near agricultural areas are often at a higher risk of nitrate contamination.
How do I know if my water has nitrates?
Nitrates are colorless, odorless, and tasteless, so the only way to know if they are present is through water testing. A professional lab analysis can determine nitrate levels and identify other water quality concerns.
What are the symptoms of nitrates in drinking water?
Nitrates do not usually cause noticeable symptoms in healthy adults. However, high nitrate levels can be dangerous for infants, pregnant women, and vulnerable individuals.
They may reduce the blood’s ability to carry oxygen, causing symptoms such as shortness of breath, fatigue, headaches, dizziness, and a bluish tint to the skin, lips, or fingernails. In infants, nitrate exposure can lead to a serious condition known as methemoglobinemia, or “blue baby syndrome.”
What is the best way to remove nitrates from water?
Reverse osmosis is one of the most effective methods for removing nitrates from drinking water. These systems use a specialized membrane to reduce dissolved contaminants before the water reaches your faucet.
Does a water softener remove nitrates?
No, standard softeners are not designed to remove nitrates from water. If nitrates are present, a reverse osmosis system or another specialized treatment solution is typically recommended.
Can boiling water remove nitrates?
No, boiling water does not remove nitrates and may actually increase nitrate concentrations as water evaporates. Proper water treatment is needed to reduce nitrate levels.
How often should well water be tested for nitrates?
The EPA recommends testing private well water for nitrates at least once per year. More frequent testing may be needed after flooding, well repairs, or changes in local groundwater conditions.
