Sodium (Na) in drinking water
The Regional Municiplaity of York has advised the Town of moderatey elevated levels of sodium (Na) in the municipal drinking water.
The Region has reported an average sodium concentration of 34mg/l in 2019, and elevated concentrations of sodium on April 1, 2020 at the Georgina Water Treatment Plant (32.5mg/l) and at the Sutton Elevated Tower (32.3mg/l). When test results for sodium exceed 20mg/l, the Safe Drinking Water Act requires the Region to report this as an adverse test result to the Ministry of Environment, Conservation and Parks (MECP) and to the Regional Medical Officer of Health.
Sodium is not considered toxic in moderate levels, however, many people consume more sodium than the recommended intake of 1500mg/day. Sodium is found in most food, soft and mineral water, and in most medication we ingest. As such, sodium in drinking water is not a health concern for majority of people, however, may cause concern for individuals with severe hypertension, congestive heart failure or whom have been prescribed a sodium-restricted diet. The moderately elevated levels of sodium in the Towns drinking water does not cause concern for taste or odour as the concentration is far below the taste and odour objective limit of 200mg/l.
