What to Test for

Your drinking water looks, tastes, and smells fine, why test it?

Here’s Why:

  • Germs, chemicals and toxic waste in or on the ground can pollute your drinking water under the ground. You might not see, smell, or taste them.
  • Some local rocks contain harmful substances that can dissolve into your well water.

If you have never tested your well water, test for everything listed below. After this first complete test, you can follow the schedule below that spreads out the tests and the costs. For a list of labs that test well water click here.

Additional Tests

Pollutant Why?
Arsenic If you live near agricultural land – especially fruit orchards or land that was a fruit orchard. Also, if you live near industrial sites.
Beryllium Occurs naturally in the bedrock in some areas of Rhode Island, including East Greenwich, West Greenwich, Coventry, Exeter, western Cranston, Johnston and Scituate.
Copper If your plumbing system has copper pipes it is possible that the copper in the pipes can dissolve into the water.
Man-made Chemicals In some areas of the state industrial solvents, manufacturing chemicals, ammunition wastes, and pesticides have been detected in groundwater. Contact the Rhode Island Department of Health for information about areas of known drinking well water pollution.
Radon There is no drinking water standard for radon. However, radon in the water can contribute to radon levels in indoor air, which is of greater concern.
