WebA major portion of stable and radioactive strontium in soil dissolves in water, so it is likely to move deeper into the ground and enter groundwater. However, strontium compounds may stay in the soil for years without moving downward into groundwater.

WebStrontium can be found naturally in many drinking water sources across Canada. Groundwater typically contains higher levels of strontium than surface water because it may have been in contact with minerals and rocks containing strontium. Human activities such as mining and manufacturing operations can also release strontium into water.
