Wells in Vaughan

How testing works in Ontario
Free bacteria testing through Public Health Ontario labs: pick up a kit at a PHO lab or your public health unit and drop it back off. Chemistry (nitrate, sodium, metals) goes to a licensed private lab for a fee. Local health units recommend testing at least three times a year: spring, summer and fall.
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.
