Standard Well Water Panel
The cornerstone test for understanding your water. If you are not sure where to start, start here.
Start With the Standard PanelThe Starting Point for Private Well Testing
Most homeowners do not begin with a specific contaminant in mind. They begin with a question: “Is my water safe?”
The Standard Well Water Panel answers that question. It establishes a baseline across the most common contaminants found in Maine groundwater and gives you a clear picture of your water quality.
This is the test most homeowners use first. From there, additional testing—such as PFAS or radon— can be added based on results, location, or specific concerns.
What the Standard Panel Covers
The Standard Well Panel is designed to capture the most common risks in private well water.
Bacteria
Detects coliform and E. coli contamination, one of the most immediate risks to drinking water.
Nitrates
Identifies contamination from septic systems, fertilizers, and environmental sources.
Metals
Screens for naturally occurring elements such as arsenic, manganese, and other groundwater metals.
These three categories form the foundation of well water testing and are recommended as a baseline by state and national guidance for private wells.
How the Standard Panel Fits Into Testing
Think of the Standard Panel as the first step in a larger process. It answers the question: “What is happening in my water right now?”
Based on those results, homeowners may choose to expand testing. For example:
• Add PFAS testing if there is concern about environmental exposure
• Add radon testing to evaluate air and water interaction
• Repeat testing over time to monitor changes in water quality
This approach avoids guesswork and focuses testing where it actually matters.
Why the Standard Panel Matters
Many of the most important contaminants in well water cannot be seen, smelled, or tasted. A clear glass of water does not guarantee safe water.
The Standard Panel gives homeowners a reliable baseline. From there, decisions about treatment, filtration, or additional testing can be made with confidence.
Without a baseline, every decision is a guess. With it, every decision becomes informed.
