Well Water Testing (Private Drinking Water)
We provide testing for the presence of the bacterial indicators of contamination, E. coli and total coliforms in private drinking water systems. This information is for people who rely on drinking water from a privately owned water source such as a well and other private drinking water systems (e.g., water from cisterns, treated lake water).
As of May 4, 2020, some drinking water samples sent to the PHO Laboratory, Hamilton will be transferred to the Ministry of the Environment, Conservation and Parks (MECP) Laboratory Services Branch for analysis until further notice. There is no charge for this testing and regular options for accessing the test results will still be available.
If you dropped your sample off at the PHO Laboratory, Hamilton or at a drop off location advertised by one of the following public health units: Brant County, Halton, Hamilton, Niagara and Wellington-Dufferin-Guelph, and do not wish to have your sample transferred, please contact firstname.lastname@example.org. They will arrange to have the analysis cancelled.
If the sample has already been transferred and the results are available, they will be reported. A list of alternate licensed laboratories can be found on the MECP website.
