How We Analyze Your Samples
Water testing is not guesswork. It is a structured process built on measurement and documentation.
At Chanalytical Laboratories, every sample moves through four clear steps: collect, process, analyze, report. That sequence keeps the focus where it belongs — on measured facts.
Below is a closer look at what that process means and why it matters.
1. Collect & Drop Off
The process begins with collection.
We collect a water sample from you or at one of our drop-off locations. The condition of the sample at that moment reflects what is present in your water at the time of collection.
The Centers for Disease Control and Prevention explains why collection matters:
“Testing your well water is the only way to know if your well is contaminated.”
(CDC, Testing Well Water: https://www.cdc.gov/healthywater/drinking/private/wells/testing.html)
The key phrase is “at the time.” Water quality can change due to seasonal conditions, rainfall, or system factors. The collected sample represents a snapshot.
That snapshot begins the analytical process.
2. Process the Sample
Once received, the sample is logged, handled, and prepared for the requested analyses.
Processing ensures the sample is organized and prepared for accurate measurement. Depending on what is being tested, preparation may involve separating portions of the sample, preserving it appropriately, or readying it for instrumental analysis.
The U.S. Environmental Protection Agency notes:
“Water testing identifies the presence and concentration of constituents in your water.”
(EPA, Private Drinking Water Wells: https://www.epa.gov/privatewells)
Before those concentrations can be measured, the sample must be prepared correctly. Processing is the bridge between collection and analysis.
3. Analyze in the Lab
After preparation, technicians use specialized instruments to measure various analytes through precise methods.
This is where numbers are produced.
Laboratory analysis does not speculate. It measures. Instruments are designed to detect specific substances and report their concentration in defined units.
The U.S. Geological Survey emphasizes the importance of measurement in understanding groundwater:
“Groundwater quality changes over time as a result of natural and human influences.”
(USGS, Water Quality Trends: https://www.usgs.gov/mission-areas/water-resources/science/water-quality-trends)
If water quality changes over time, then measurement at a specific point becomes essential. Analysis provides that measurement.
Different instruments are used depending on the analyte. Some methods are designed to measure dissolved metals. Others identify biological indicators. Others quantify dissolved gases.
Regardless of the analyte, the purpose remains consistent: determine what is present and in what amount.
4. Report Your Results
Once analysis is complete, the findings are compiled into a clear report.
That report shows what was measured at the time of testing in a readable format.
It lists:
- The analyte
- The measured value
- The units
The CDC reinforces why that clarity matters:
“You cannot taste, see, or smell many types of contamination.”
(CDC, Testing Well Water: https://www.cdc.gov/healthywater/drinking/private/wells/testing.html)
Because many substances are invisible, the report becomes the primary tool for understanding what is present.
The report does not guess. It does not predict. It documents.
No Guesswork — Just Measured Facts
Water testing is important because assumptions are unreliable.
Clear water does not automatically mean known water. Environmental factors, seasonal changes, and natural geology can influence what appears in groundwater.
The EPA explains:
“Private well owners are responsible for the safety of their drinking water.”
(EPA, Private Drinking Water Wells: https://www.epa.gov/privatewells)
Responsibility begins with information.
The four-step procedure — collect, process, analyze, report — provides that information in a structured and transparent way.
Why the Process Matters
Each step supports the next.
- Collection captures a moment in time.
- Processing prepares the sample for accurate measurement.
- Analysis produces measurable data.
- Reporting documents what was found.
This sequence ensures clarity. There are no shortcuts. There is no interpretation layered onto the data.
There are measured facts.
Chanalytical Laboratories follows a four-step procedure: collect and drop off, process the sample, analyze in the lab, and report the results. Each step is designed to provide clear, measurable data about what was present in your water at the time of testing. Water testing replaces guesswork with documented information, allowing decisions to begin with facts.
