Contaminants & Testing Frequency:

NH DES recommends the following tests every 3 to 5 years, except for bacteria and nitrate testing, which NH DES recommends to be conducted annually.

Water Test Instructions:

If the well has recently been chlorinated, please make sure there are no residual traces of bleach in the water. Bleach will affect the results.

  1. Remove the aerator screen from the faucet and turn on the cold water for 5 minutes.

  2. Turn the water down to a slow, steady stream. Fill bottle labeled INORGANIC first.

  3. If you have chosen a package that includes radon, remove the cap from the vial and fill very slowly until the water is almost overflowing from the vial. Fill the cap with water and replace the cap and tighten completely. (This will help eliminate air)

  4. Turn the radon vial upside down and tap to check for the presence of air. If air is present, unscrew the cap and carefully add a few more drops of water to the vial. *The presence of air in the radon vials will lead to inaccurate results.

  5. To collect water for the BACTERIA analysis, turn off the water and disinfect the faucet. A cotton ball with bleach works well. Run the water for an additional 5 minutes.

  6. Turn the water back down to a slow, steady stream. Now fill the sealed and sterile bacteria bottle, containing a tablet, to above the line marked 100mL.

  7. Water test kits must be brought to Granite State Analytical office in North Conway before 3 PM the same day (M - Th) as the collected water sample.
