Methods and systems are provided for treating a contaminated environmental medium. In one example, the treatment includes adding a salt to the contaminated environmental medium to form a slurry. The slurry is heated to irreversibly precipitate a jarosite-group mineral incorporating contaminant cations and contaminant anions into its structure.
