Wells in Vaughan
Vaughan gets Lake Ontario water through York Region, but the city also includes rural land in the north, and York Region notes that some residents get water from private wells on their property.
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.
