Re: Global News feature on Trumpeter Swans dying in Abbottsford
Lead can be soluble in groundwater (and surface water), however that solubility is dictated by the pH (acidity/alkalinity) and hardness of the water. The more acidic the water is, typically the hardness (mg/L CaCo3 equivalent) is lower, and the lead becomes more soluble.
In BC the lead content in drinking water is regulated under the Contaminated Sites Regulation (via Health Canada), and the permissible dissolved lead content in drinking water is 10 ug/L. For freshwater aquatic life use, the permissible dissolved lead content varies from 40 to 160 ug/L and is dependent on hardness of the water.
Drinking rum before 10 a.m. does not mean you are an alcoholic, it means you are a pirate.
