Water Testing

If the home you are purchasing has a well, we recommend that you have the water tested to be sure it is safe, unless it has been tested by the previous owner in the last year.

We offer three basic types of tests:

  • The standard mortgage test: includes testing for: PH, Copper, Lead, Chloride, Iron, Arsenic, Hardness, Manganese, Sodium, Nitrates/Nitrites, Coliform/E, Coli, Flouride.

  • First draw lead: If your home was built prior to 1990, lead solder was often used in the plumbing fixtures, and this lead can contaminate your water.
  • Radon water: This test is not recommended unless you have a high radon air concentration or have a radon mitigation system installed.

It is estimated that 40 to 60 percent of the wells in Idaho are contaminated with coliform bacteria. Coliform bacteria is not necessarily harmful, but the presence of coliform bacteria is an indicator that other disease carrying micro-organisms may be present. Bleaching the well will usually clear coliform bacteria from the well. For more information on well bleaching, see Idaho well water brochure or read drinking water.

The test sample must be drawn on Monday thru Thursday and cannot be drawn on the day before a holiday. Otherwise the sample will get to the lab when it is closed and will not be tested in time. So if you are planning your inspection on a Friday and would like to have the water tested, this will require an additional trip to the property to obtain the water sample, at additional cost. Also note that the sample must be taken early enough in the day so that it can be received at the shipping office before 5:00 pm.

If the water sample fails and the well needs to be bleached or otherwise re-conditioned, any additional testing will be at additional cost.
