The City of Brantford has reaffirmed its commitment to providing safe and reliable drinking water, announcing proactive measures to address seasonal changes in nitrate levels observed in the Grand River during winter months. City officials emphasized that Brantford’s water supply undergoes rigorous daily testing to meet or exceed provincial health and safety standards, ensuring public confidence in the water quality delivered to homes and businesses.
Nitrate, a naturally occurring compound, is typically present in surface water and groundwater at low levels. However, during the winter, reduced biological activity in the Grand River can result in higher nitrate concentrations. Unseasonal warm temperatures or heavy rain can exacerbate these conditions by increasing nitrate runoff from agricultural and industrial sources.
City officials confirmed that current nitrate levels in the water supply remain well below the Maximum Acceptable Concentration (MAC) of 10 milligrams per litre (mg/L) as nitrogen, established by the Ministry of the Environment, Conservation and Parks (MECP). The City continues to work in close collaboration with Grand Erie Public Health, the Grand River Conservation Authority, and the MECP to monitor and manage nitrate levels to maintain public safety.
Health Canada has identified vulnerable populations, including bottle-fed infants under six months, babies one year old and younger, and expecting mothers, as most at risk if nitrate levels in drinking water exceed the MAC. Excessive nitrate consumption in these groups can lead to methemoglobinemia, or “blue baby syndrome,” which impairs oxygen transport in the blood. City officials assured the public that nitrate levels in Brantford’s water distribution system have never exceeded the regulatory threshold.
In the unlikely event that nitrate levels surpass 10 mg/L for an extended period, the City will take immediate action, including utilizing stored water reservoirs and providing bottled or potable water to vulnerable populations. Public advisories would be promptly issued to ensure transparency and safety.
Residents seeking further information are encouraged to visit Brantford.ca/nitrate, where a detailed FAQ document is available. Additionally, a comprehensive staff report and presentation on nitrate levels will be delivered to Brantford City Council on January 21 at 6 p.m., accessible through the City Council calendar page at calendar.brantford.ca/meetings.
The City of Brantford remains dedicated to safeguarding public health and providing timely updates as part of its commitment to the community.
