Private Well Water Supplies - Safe Water

The goal of the Safe Water program is to reduce the number of people who become ill from drinking or coming in contact with contaminated water.

  • Many rural residents rely on private wells and cisterns as their drinking water source.  In Hamilton, it is estimated that there are approximately 10,000 wells in use.  Testing of private water wells are the responsibility of each homeowner.  To ensure your well water is safe to drink, Public Health Services recommends testing your well water at least 3 times each year for bacteria (a free service from the City).

    Rural City of Hamilton residents who use a drilled water well located above the Niagara Escarpment as their main source of drinking water are advised that there is the potential for high lead levels in some wells due to naturally occurring lead in the bedrock. The Medical Officer of Health advises these residents to have their water tested for total and dissolved lead.
