Comprehensive Ontario Drinking Water Standards Testing

Full-Spectrum Testing to Guarantee Safe, Clean Drinking Water

Why Test for Ontario Drinking Water Standards?


Testing for Ontario Drinking Water Standards is critical to ensuring that your drinking water is safe, clean, and free from harmful contaminants. The Safe Drinking Water Act (SDWA) and Ontario Regulation 169/03 establish a comprehensive framework for ensuring that water systems meet specific chemical, microbiological, and physical parameters. This includes guidelines for contaminants such as bacteria, nitrates, pH levels, heavy metals, chlorine, arsenic, lead, and more.


While potable water testing typically refers to general assessments that verify if water is safe for consumption (focusing on a select few high-risk parameters), comprehensive ODWS testing refers to a full-spectrum analysis of all parameters outlined in Ontario's official standards. In other words, potable testing may confirm that your water is drinkable — but ODWS testing ensures your water meets every legal and regulatory threshold required by the province.


Comprehensive testing allows for the early detection of any harmful elements in drinking water, helping businesses, municipalities, and private property owners maintain safe water supplies and comply with provincial regulations.


Comprehensive Ontario Drinking Water Standards Testing includes all key parameters as listed under Ontario Regulation 169/03, which governs drinking water quality in Ontario. With this full spectrum of testing, you can be confident that your water meets the highest safety standards and remains safe for consumption.


Regular testing is not only essential for compliance but also helps avoid potential health hazards. Undetected contamination can lead to outbreaks, illnesses, or long-term health issues. By performing thorough testing across all water quality parameters, we give you the peace of mind that your water is safe for all users.

Comprehensive Testing for All Ontario Drinking Water Parameters

Comprehensive Testing for All Ontario Drinking Water Parameters

We conduct testing across a wide range of parameters, as required under the Ontario Drinking Water Standards, including:

- Microbiological Testing (e.g., E. coli, total coliforms)

- Chemical Testing (e.g., lead, arsenic, nitrate levels, chlorine, fluoride, pesticides, heavy metals)

- Physical Testing (e.g., turbidity, pH levels, color)

- Inorganic Compounds (e.g., ammonia, sulfate, phosphate)

- Organic Compounds (e.g., volatile organic compounds like benzene, toluene, and chlorinated solvents)


These tests allow us to detect any substances that could compromise the safety and quality of drinking water. Comprehensive testing is essential for meeting Ontario’s drinking water standards and ensuring water is safe for consumption and use.

Stay Compliant with Ontario Drinking Water Regulations

Regular testing for all Ontario Drinking Water Standards is mandatory for municipalities, industrial water systems, and private water suppliers to ensure that drinking water remains free from contaminants. Ontario’s Safe Drinking Water Act (SDWA) and Ontario Regulation 169/03 stipulate maximum acceptable concentrations (MAC) for various contaminants to protect public health.


Failure to comply with these standards can lead to serious consequences, including fines, legal liabilities, and public health concerns. By performing comprehensive testing, we help you stay compliant with these regulations and safeguard your water supply.

Prevent Contamination and Ensure Safe Water for All

Prevent Contamination and Ensure Safe Water for All

Drinking water contamination is a serious health risk that can lead to illness, long-term health effects, and costly damage to systems. Some common contaminants, such as lead and arsenic, are especially harmful when consumed over time and can cause chronic health issues, particularly for children and vulnerable populations.


Testing for all the key parameters outlined in the Ontario Drinking Water Standards ensures that these contaminants and others are within safe levels and do not pose a threat to health. Our comprehensive testing program provides a proactive approach to water safety, identifying risks early and allowing you to take necessary actions before issues escalate.


We offer complete certified sampling, lab analysis, and detailed reports that outline your water’s compliance with Ontario’s stringent regulations. By partnering with Canadian Water Compliance, you ensure the health and safety of those who rely on your water supply.
