Nitrate Water Testing
Identify a common groundwater contaminant that can impact drinking water safety.
Schedule Nitrate TestingWhat Are Nitrates?
Nitrates are naturally occurring compounds that can enter groundwater through fertilizers, septic systems, animal waste, and natural soil processes. They are one of the most commonly detected contaminants in private wells.
Nitrates dissolve easily in water and cannot be seen, smelled, or tasted, making laboratory testing the only reliable way to detect them.
Nitrates in Maine Wells
In Maine, nitrate contamination is most often associated with rural areas, septic systems, and agricultural activity. Because many homes rely on private wells, testing becomes a routine part of responsible ownership.
The Maine CDC recommends regular testing of private well water for nitrates,
particularly when there are infants in the household or when the well is
located near potential sources of contamination.
Maine CDC Nitrate Guidance
Testing is also recommended when buying or selling a home, or when there are changes in land use or nearby environmental conditions.
Why Nitrate Testing Matters
Elevated nitrate levels can present health risks, particularly for infants. In these cases, nitrates can interfere with the blood’s ability to carry oxygen, a condition sometimes referred to as “blue baby syndrome.”
Because nitrates move easily through soil and groundwater, levels can change over time. A well that previously tested clean may show elevated levels later.
National health guidance recommends routine nitrate testing for private wells,
especially in households with vulnerable populations.

How Chanalytical Supports Nitrate Testing
Chanalytical provides local, laboratory-grade nitrate testing for Maine homeowners. The focus is on delivering clear, reliable results that support informed decisions.
The process is designed to be simple and practical:
• Guidance on when nitrate testing is appropriate
• Proper sample handling support
• Convenient drop-off locations across Maine
• Clear, actionable lab results
What Happens If Nitrates Are Found?
Detection does not mean immediate danger, but it does require attention. The appropriate response depends on the level detected and how the water is being used within the home.
Treatment options such as reverse osmosis systems are commonly used to reduce nitrate levels in drinking water. In some cases, identifying and addressing the source of contamination may also be necessary.
Testing provides the baseline needed to make these decisions with confidence.
Test With Confidence
Nitrate levels can change over time. Regular testing helps you stay ahead of potential risks.
