| Abstract |
Extreme acid-rock drainage is the dominant long-term environmental concern at the Summitville mine and could have been predicted given the geological characteristics of the deposit. Extensive remedial efforts are required to isolate both unweathered sulfides and soluble metal salts in the open-pit area and mine-waste piles from weathering and dissolution. Results of studies as of late 1993 indicate that mining at Summitville has had no discernible short-term adverse effects on barley or alfalfa crops irrigated with Alamosa River water. Remediation of the site will help to ensure that no adverse effects occur over the longer term. -from Editor |

| Abstract |
Nach einer Definition der Wetlands wird ihre zunehmende Bedeutung als kostengünstige, ästhetische und nahezu wartungslose Alternative zur chemischen Aufbereitung saurer und schwermetallbelasteter Grubenwässer erläutert. Es werden die physikalischen Voraussetzungen behandelt und unter Bezugnahme auf ein umfangreiches Schrifttum die chemischen und mikrobiologischen Prozesse, die in Wetlands ablaufen, tabellarisch aufgelistet und detailliert unter Angabe der möglichen Reaktionen erläutert. Anschließend werden der Aufbau und die Funktionsweise der einzelnen Komponenten eines Wetlandsystems vorgestellt und die unterschiedlichen Typen der möglichen Ausführungsvarianten erläutert, was durch bildliche Darstellungen illustriert wird. Es wird ein Überblick zur Anwendung von Wetlands in Australien vermittelt. Die bei diesen Anwendungsfällen erzielten Ergebnisse werden diskutiert. Es werden Hinweise zur Planung sowie zur Anordnung der Wetlands gegeben, die auch grobe Kostenabschätzungen enthalten. |

| Abstract |
Passive-treatment systems that mitigate acid-rock drainage from coal mines have been operating since the mid-1980s. Large systems at metal mines are being contemplated. A typical man-made passive-treatment-system can mimic a natural wetland by employing the same geochemical principles. Passive-treatment systems, however, are engineered to optimize the biogeochemical processes occurring in a natural wetland ecosystem. The passive-treatment methodology holds promise over chemical neutralization because large volumes of sludge are not generated. Metals may be precipitated as oxides, sulfides or carbonates in the passive-treatment system substrate. The key goal of a passive-treatment system is the long-term immobilization of metals in the substrate materials. The passive-treatment technique may not be applicable in all mine-drainage situations. -from Author |
