If you're buying a home on a well, it is recommended you have a water test as part of the inspection process. Most tests consist of collecting a sample and having it sent to a local, provincial-certified lab for analysis.
Well water should be tested for the presence of bacteria (e-coli, total coliform, nitrates, nitrites, total nitrates-nitrites, Ph, iron, lead and turbidity) and chemical contamination (including arsenic).
Organic (Bacteria) Test: $100 plus HST
Inorganic (Chemicals & Metals) Test: $200 plus HST
