Arsenic, uranium, radon, bacteria

When the lab flags more than a stain

Some lines on a report are compared with a health-based limit. A flag there is a reason to plan, not a reason to rush.

Granite-state bedrock can carry arsenic, uranium and radon into well water. None of them show in color or taste, which is why the lab report is the only way to know.

We read the report with you, and the treatment follows the form and the amount the lab reports.

  • Do this firstRead the lab's own note. If it names a health-based limit, ask the lab or the state's drinking-water program what to drink and cook with until you have a plan.

We explain reports and install systems. We are not a health service.

What the lab can flag

  • Arsenic

    Some treatments depend on the form of arsenic. We may ask the lab for a second analysis before proposing anything.

  • Uranium

    Treated at the tap you drink from, or for the whole house, depending on the amount and your use.

  • Radon in water

    A gas that leaves the water into the air of the house. The report number and an air test together set the answer.

  • Coliform bacteria

    A sign something has reached the well or the plumbing. The well and plumbing are disinfected and retested before anything else.

What we promise

A retest on the record

We cannot tell you the result before the system runs. What we do is send a second sample to the same lab after it has, and sit down with both reports side by side.

If the number has not moved enough, we say so and look again, in writing.

  • The same lab, the same panel, the same bottles

  • Both reports in your hands

  • Terms in the proposal, in plain words

Questions about the flagged lines

Is my water safe to drink?

We cannot say that. Ask the lab about your report, and the state's drinking-water program about the limit it names.

Can one filter do all of it?

Sometimes. Different lab flags need different treatment, so the proposal lists what each part of the system is for.

My house was built before 1986. Should I test for lead too?

A house plumbed before 1986 can have lead solder or fixtures. A lab can test at the tap, and we can add it to your sample.

Send the report, then decide

We will tell you which lines are the lab's concern and which are only about stains.
