Sodium in drinking water


Sodium is a nutrient found in table salt and many other foods. Your body needs some sodium to function, but too much may lead to high blood pressure (a major risk factor for stroke, heart disease and kidney disease). Most Canadians take in more than twice the amount of sodium they need in a day.*

In Oxford County, natural sodium levels in drinking water are high enough that people on a sodium-restricted diet should be aware of how much sodium they are taking in through their water. 

For a healthy adult, the level of sodium in the water supply does not pose a risk to health.  However, if you or members of your family have kidney disease, heart disease, high blood pressure or liver disease, and need to restrict your salt intake because of these illnesses, please ask your physician or health care professional how sodium in the water may affect your health.  


 

Monitoring sodium in municipal drinking water


The County of Oxford tests for sodium in drinking water every five years. To find out what the sodium levels are in your community’s drinking water, visit the online annual drinking water reports on this website: Drinking Water | Annual Reports

Oxford County municipal water containing sodium levels under 200 mg/L is considered safe for drinking.

When sodium levels are higher than 20 mg/L, the Medical Officer of Health is required to inform the public, through health professionals, in order to help people on sodium-restricted diets control their sodium intake. 

The bacteriological safety of municipal drinking water is not affected by sodium levels, meaning that the water is safe to drink.

For more information regarding water systems with over 20 mg/L of sodium, read the latest Health Information Advisory.
