Abstract

See full text

Methods and systems are provided for treating a contaminated environmental medium. In one example, the treatment includes adding a first jarosite-group mineral to the contaminated environmental medium to form a wet mixture under a set of conditions. The set of conditions is maintained over a duration of time to expedite precipitation of a second jarosite-group mineral, the second jarosite-group mineral incorporating contaminant cations and contaminant anions into a structure of the second jarosite-group mineral. The first jarosite-group mineral is added in situ at a contamination site.
