When ash falls to the ground, the soluble components (leachates) can by washed away by water, potentially resulting in changes to local water chemistry and hence quality.
-
Observations from historical eruptions show that concentrations of hazardous leachates in ash decrease with increasing distance from an erupting volcano, with few examples of serious chemical contamination of portable water supplies.
