200296 Community participatory driven research; Comparisons of water quality variables and concentrations of toxic elements downstream from Allegheny River gravel mining operations during periods of activity and inactivity
Tuesday, November 10, 2009: 5:06 PM
River mining for sand and gravel have a long history in Southwestern Pennsylvania, their abundance in the drainage is responsible for the emergence of the glass and construction composite industries, respectively. Employed CBPR methodologies found community values connected with increasing use of the river for recreational and residential uses are at odds with historical economic use patterns. River mining has been shown to cause numerous environmental impacts, primarily substrate and depth changes resulting in anoxic hole formation. We sought to compare indicators of water quality and concentrations of a suite of elements downstream from active mining operations (2-4 hours after onset) with those obtained during periods of inactivity (8 hours post cessation). Elemental analysis was done using ICP-MS methods. Elemental concentration data were analyzed for significant differences (alpha .05) using a paired sample t-test using SPSS Version 16 software. Significantly elevated concentrations of arsenic (p < .001), selenium (p = .027) and zinc (p = .018) were found in river water after onset of mining operations compared to pre-mining levels. Turbidity levels at all sampling stations at all depths were higher after onset of mining operations than before mining onset (p < .001; 95% CI of Mean Difference 2.36 to 4.05 FTD units). The overall environmental public health significance of this work is that it shows that river mining adds significant masses of sediment specific toxic elements to surface waters that are used as a drinking water source for downstream communities and for bank filtration well water users.
