The best time to test for contaminant in well water is during the spring or summer following a rainy period.
Testing for bacteria should be conducted after repairing or replacing a well pump or piping. If a new baby is expected in the home, it is a good idea to test for bacteria and nitrate in the early months of a pregnancy and again during the first six months of the baby’s life.
If any older person or anyone with a low immune system is going to live in the house, check for bacteria and possibly nitrate/nitrite.
When purchasing a property with a well, the water should always be tested for bacteria. Additional tests can be performed depending on the situation for nitrate/ nitrite, lead or any specific chemical that you may require
