Clear water is not necessarily safe drinking water. Some harmful contaminants have no obvious taste, odor or color, which is why private well testing matters even when the pump and plumbing appear to work perfectly.
What the CDC recommends annually
The CDC recommends that private well owners test at least once each year for total coliform bacteria, nitrates, total dissolved solids and pH. Other testing depends on local geology, land use, past contamination, nearby activities and household health considerations.
Use a state-certified laboratory and carefully follow its sampling directions. A result is only as useful as the collection and handling behind it.
Know what different tests answer
A coliform result helps screen for possible microbial contamination pathways. Nitrates are especially important where vulnerable household members may be exposed. Total dissolved solids and pH give broader information about water chemistry but cannot establish the absence of all harmful substances.
If the water has staining, unusual taste or odor, ask a qualified professional whether additional tests for iron, manganese, hardness, sulfate or other constituents are appropriate. Regional geology may warrant other panels as well.
Test after significant changes
The EPA advises additional testing when water appearance changes, after flooding or when nearby land activities could affect the well. Repairs to the system may also call for follow-up testing. If contamination is suspected, avoid assuming the problem can be fixed with a generic filter.
Make the laboratory conversation practical
Before collecting a sample, tell the laboratory whether you are checking a new well, following up on a repair or investigating a change in the water. Ask which sample containers to use, where to collect the sample, and how quickly it must reach the laboratory. Follow its instructions rather than reusing a household bottle or choosing a sampling point by guesswork.
Keep the report with your well records. Note the sampling date, sampling location, any treatment equipment in use and recent repairs or flooding. These details give a qualified professional useful context when comparing results over time.
Keep water quality separate from drilling yield
A well that pumps strongly may have unsuitable drinking-water quality, while a low-yield well could still have acceptable chemistry. Analyze both independently. Treatment choices should follow certified test results and a qualified recommendation.
Does boiling remove nitrates and dissolved minerals?
No. Boiling does not reliably remove those chemical contaminants and can increase their concentration as water evaporates. Follow public-health and laboratory guidance for a safe response.
