New Brunswick’s routine testing schedule
Current provincial guidance recommends checking bacterial quality twice a year, ideally around spring thaw and fall rains, and testing inorganic parameters such as arsenic, uranium, fluoride and nitrate every two years. Additional testing is recommended after flooding, heavy rain, well work or noticeable changes in the water.
A special step for newly drilled or repaired wells
New Brunswick says that when a well is drilled, deepened or repaired, the homeowner receives a testing voucher from the well contractor for inorganic and microbiological analysis. Keep that result with the well log and property records.
Where New Brunswick owners can test
- Use an SCC- or CALA-accredited laboratory for the parameters required.
- RPC Analytical Services is the designated provincial analytical laboratory, with designated Service New Brunswick locations used for bottle pickup and sample drop-off.
- Use the laboratory’s bottles and collection instructions; bacteria samples in particular have strict handling and delivery requirements.
Why the local geology still matters
Inorganic contaminants can originate naturally from rock formations, so the actual property’s chemistry result matters more than a neighbour’s result. A well record adds construction and location context but does not replace water-quality testing.
