Stormwater runoff raises concern over potential downstream impacts of selenium (Se) on aquatic ecosystems. Constructed wetland phytoremediation is a sustainable, inexpensive, eco-friendly technology with potential to remove Se from stormwater. The objectives of this study were to: 1) evaluate the bioavailability of Se chemical form and concentration on plant uptake and 2) determine the potential of aquatic macrophytes to improve water quality in a constructed wetland. The experiment was arranged as a 2 X 2 factorial nested within a split-split plot design replicated three times. Cattail (CT; Typha angustifolia L.), duckweed (DWD; Lemna minor L.), fanwort (CAB; Cabomba caroliniana A. Gray), soft rush (SR; Juncus effuses L.), muskgrass (MG; Chara spp.), and unplanted controls (UNP) were acclimatized 14 d in 115-L microcosms containing 0.035 m of Catalpa silty clay loam with 26 L of water supplemented with 0.1 N Hoagland’s solution. Selenium treatments were applied as a 4-L solution of either sodium selenite (SeO3 ) or sodium selenate (SeO4 ) to a total volume of 30 L at 0, 500, or 1000 μg Se L. Water samples were collected daily for six days. Plant and soil samples were collected prior to Se application and at three-day intervals post Se application. Water, plant, and soil samples were analyzed for total [Se] by inductively coupled plasma-mass spectrometry. Data were analyzed with PROC GLM at α=0.05. After six days, CT and MG-planted microcosms significantly decreased aqueous [Se] by 75 and 74%, respectively, compared to 61% for UNP. The aqueous fraction of microcosms planted to CAB, DWD, and SR were similar to UNP controls. Plant tissue Se content in CT was significantly less than CAB, DWD, or MG, suggesting CT has the potential to volatilize Se. Given its abundance and efficacy, CT is likely a suitable species for Se removal in constructed wetlands supplied with either selenite or selenate-impacted waters.

These contaminants are often particularly difficult or expensive to remove using conventional water treatment methods, such as chemical coagulation/precipitation, reverse osmosis filtration, ion exchange, etc. Treatment system capital and operating expenses combined with additional costs of sludge or concentrate stream disposal, are driving research and application of biotreatment methods for removal of these contaminants from mining and industrial wastewaters. This paper discusses application of the Electro-Biochemical Reactor (EBR) technology for Se, U, and NO3 bio-reduction and removal from mining wastewaters. Three case studies are presented, based on laboratory benchand onsite pilot-scale trials with significantly different mining waters (flotation-influenced base metals mine water, leach solution from a gold mine, and coal mine seepage water), each contaminated with varying concentrations of Se, U, and NO3. Average concentrations of these contaminants were 2,712 μg L Se, 2.0 μg L U, and 1.53 mg L NO3-N (Site A); 2.9 μg L -1 Se, 92.5 μg L U, and 189 mg L NO3-N (Site B); and 105 μg L Se, 18.4 μg L U, and 50 mg L NO3-N (Site C). The EBR technology was demonstrated on all three sites to treat the waters to <0.5 – 3.2 μg L Se, <0.1 – 0.8 μg L U, and <0.02 – <2 mg L NO3-N.","PeriodicalId":17230,"journal":{"name":"Journal of the American Society of Mining and Reclamation","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73825524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Flight 93 National Memorial is located in Somerset Co., near Shanksville, PA. The site was surfaced mined and much of the 890 ha of reclaimed land was re-contoured and seeded in the mid 1990’s. Starting in the spring 2012, the National Park Service, Office of Surface Mining Reclamation and Enforcement, and others have worked to reforest sections of the total area using native woody trees and shrubs. Each spring for the past six years (2012-17) over 500 volunteers planted a new section, which we have defined as a “Phase,” of the National Memorial. The Flight 93 National Memorial Reforestation Project was established to evaluate reforestation success and provide data to drive future management decisions. Specifically, this work aims to: O1) Determine abundance and percent stocking for each of the 34 native, woody species planted across the six Phases; O2) evaluate growth of woody plants; and O3) describe level of competing vegetation across each phase. Two hundred and sixteen permanent, fixed radius plots were established randomly throughout the six planting phases with the goal to maintain a minimum target sampling intensity of 10%. Percent stocking, growth, and deer browse data were collected for all planted trees and shrubs within the sampling plots. Competition data was collected using 1 m rectangular sub-plots nested within whole-plot. Of the 102,393 trees and shrubs (1,792 trees ha) planted at The Flight 93 National Memorial we sampled a total of 8,673 individual trees and shrubs. Total percent stocking across all six planting Phases was 74.5% ranging from 40-121% within individual Phases, with natural regeneration driving stocking levels above 100% in one of the planting phases. Greatest plant growth was observed in the conifer species with white pine and pitch pine driving this pattern. Among the deciduous trees we observed the greatest growth among the early successional species such as quaking aspen and black locust. Overall, 88% of all plants showed no sign of deer browse, however, this rate is expected to increase as the plants emerge above the competing vegetation. Competing vegetation across all six planting phases was dominated by grasses, sedges, and herbaceous dicots and constitutes the largest limitation to woody plant establishment.","PeriodicalId":17230,"journal":{"name":"Journal of the American Society of Mining and Reclamation","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85791647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
