This report highlights select mining-influenced water (MIW) treatment technologies used or piloted as part of remediation efforts at mine sites. It is intended to provide information on treatment technologies for MIW to federal, state and local regulators, site owners and operators, consultants, and other stakeholders. Included in the report are short descriptions of treatment technologies and information on the contaminants treated, pre-treatment requirements, long-term maintenance needs, performance, and costs. Sample sites illustrate considerations associated with selecting a technology. Website links and sources for more information on each topic are also included.You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
