Health Information Advisory - Drinking Water Systems

Posted in the Announcements page on 11/17/2016 11:44:42 on Thursday, November 17, 2016.

Oxford County Public Health is issuing an annual reminder to residents about levels of fluoride and sodium in some of the County’s drinking water systems. The presence of fluoride and sodium may present health considerations for some residents.


In this year’s Health Information Advisory, municipal drinking water in Brownsville, Ingersoll, Lakeside and Tillsonburg show fluoride levels above the recommended level of 1.5mg/L. This may put children under six years of age at risk for dental fluorosis (discolouration of the teeth). Households with children under six in these communities should use bottled water for baby formula, and cutback on other sources of fluoride, like using non-fluoride toothpaste.

Sodium levels in drinking water are only a concern for individuals on a sodium-restricted diet. This includes people with kidney disease, heart disease, high blood pressure or liver disease. These residents should speak with their physician or health care provider about how sodium in the water may affect their health. Communities with sodium levels that range above the recommended level of 20mg/L include: Bright, Brownsville, Embro, Ingersoll, Norwich, Otterville, Springford, Thamesford, Tillsonburg and Woodstock.
