In Waterloo region sodium levels in municipal drinking water range from 11 - 200mg/l.. The most common source of elevated sodium in groundwater is salt (sodium chloride) applied to de ice public roadways...People may also choose to "soften" their water using a salt exchange process when the municipal water is very "hard" (high in minerals), as is the case in Waterloo Region.

This is a problem for all countries that use salt on thier roadways.

While a blood lead level of over 10 micrograms per deciliter is considered cause for concern, recent studies indicate that even blood lead levels of less than 10 micrograms per deciliter may have subtle effects on the neurological development of children. ....snip.. Tests of the City of London?s drinking water have consistently shown that the lead levels in the municipal water supply are significantly less than the 10 microgram per liter standard.

However, in 2006 and 2007, some older homes in London with lead service lines were found to have elevated levels of lead in their water when samples were taken at the tap. This was despite flushing or running the water for several minutes. Service lines are the pipes that carry the water from the water main, which runs down each street, into each home. Some homes built before 1952 may still have lead service lines. ..snip
