Abstract: Wetland development on a minesite sedimentation pond consisted of the alterations of a sedimentation pond to control water flow rates and to aid in planting cattails, rushes, sedges and other aquatic plants into the system in an attempt to reduce nutrient enrichment. It is believed that wetlands can act as a buffer between the mine working and the receiving environment. A wetland was designed and constructed to establish both aerobic and anaerobic conditions within the rougher lagoon. The aerobic cell was planted with a diversity of marsh plant species such as sedge (Carex sp) which is more desirable for water treatment purposes. The anaerobic cell uses an underflow method. Flows are adjusted using control gates and weirs. Both cells were filled with a substrate suitable for wetland development. The objectives of the project are to design and monitor the water treatment results of a large scale constructed wetland. The specific objectives will be to determine design specifications for the construction of wetlands on the other minesite sedimentation ponds, determine optimum water retention time on treatment results, quantify the removal of nitrogen from the water passing through the different wetland cells during the year and to provide information on the operation and maintenance of a wetland to enhance plant survival and growth.
