Well Water Testing

Rural residents of Ottawa are likely already aware of the free well water testing program that is available to ensure your well's water is safe. In 2014, Ottawa Public Health (OPH) took steps to improve the program to increase the convenience for rural residents to drop off water samples.

OPH has established permanent locations throughout Ottawa for well owners to drop off samples and pick up new bottles every Tuesday. The following list includes all Ottawa drop-off locations, though locations in Rideau-Goulbourn are in bold text.
