Fluoridation of drinking water back on at Pockwock Lake

Halifax Water has officially resumed the fluoridation of drinking water at its Pockwock Lake facility after more than a year-long interruption. The fluoride units at Pockwock Lake had been offline since May 2023, but the repair work at the J. Douglas Kline water supply plant has now been completed, as announced in a recent news release by the water utility.

However, fluoridation at Lake Major is still offline and has been since April 2020. Halifax Water stated that they are currently evaluating options for reintroducing fluoride back into the system at Lake Major. These options range from standalone renovations to accommodate additional tanks to incorporating solutions into the larger water supply enhancement projects planned for the water treatment plant over the next five to 10 years. There is hope that the timing for the restoration of the fluoride system at Lake Major may be sooner than anticipated.

The decision to halt fluoridation at Pockwock Lake and Lake Major was met with criticism from the president of the Nova Scotia Dental Association and Nova Scotia’s chief medical officer of health, both of whom strongly advocate for the use of fluoride in drinking water. Halifax Water faced backlash for not informing customers about the interruption in fluoridation promptly. The public only became aware of this issue after New Glasgow announced its decision to stop adding fluoride to its water supply.

Fluoride is a naturally occurring mineral that plays a crucial role in protecting teeth from cavities. The provincial Environment Department supports the fluoridation of drinking water supplies as a well-accepted measure to safeguard public health, backed by scientific evidence. Halifax Water has been adding fluoride at some of its water supply plants since the 1950s.

It is worth noting that Halifax Water’s six smaller treatment plants, including Bennery Lake, Five Islands, Bomont, Middle Musquodoboit, Collins Park, and Silver Sands, have never incorporated fluoride in the treatment process. These smaller plants cater to fewer than 300 residential customers in the Halifax Regional Municipality.

In a recent interview, the president of the Nova Scotia Dental Association emphasized the importance of protecting teeth through fluoride. As Halifax Water continues to address the fluoridation issue, it is crucial for residents to stay informed and prioritize their dental health.
