How testing works in British Columbia
There's no free provincial program: use a qualified lab (search the CALA directory), which supplies the bottles. HealthLinkBC recommends testing for bacteria at least once a year and for chemistry when the well is new and annually after that.
What to test for
- Bacteria (total coliforms and E. coli): at least once a year, and after flooding, heavy rain or work on the well.
- Nitrate, especially near farmland or septic systems.
- Metals and naturally occurring contaminants such as arsenic, uranium or manganese when a well is new and every few years after, depending on local geology.
