Nova Scotia’s recommended testing schedule
Nova Scotia’s current private-well guidance recommends testing at least every year for bacteria and every five years for chemical contaminants. A water test from a neighbour cannot establish the safety of your own well.
Why chemistry deserves attention in Nova Scotia
The province specifically highlights naturally occurring contaminants such as arsenic and uranium and provides a broader recommended chemistry panel. Those issues cannot be ruled out by a bacteria-only result or by how the water tastes, smells or looks.
How to sample and interpret the result
- Sample bottles can be obtained through Nova Scotia Health locations and other drinking-water laboratories.
- Use the receiving lab’s instructions; bacteria and chemical samples have different collection requirements.
- Nova Scotia provides an online Drinking Water Interpretation Tool to help homeowners evaluate laboratory results against current guidance.
For a Nova Scotia home purchase
Compare the current lab report with the property’s well log and inspection. If treatment equipment is installed, confirm which parameters it is designed to address and use follow-up testing to verify performance.
