Book Synopsis Spatial and Temporal Trends of Mining-related Lead-zinc Sediment Contamination, Galena River Watershed, SW Wisconsin-NW Illinois by : Dylan Alexander King

This book was released on 2018 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alluvial sediments within the Galena River Watershed were severely contaminated with heavy metals by historical zinc (Zn) and lead (Pb) mining operations during the early 1800s until 1979. Since the mines closed, there have been efforts to remediate on-site mine waste. However, the effectiveness of these efforts to reduce metal concentrations in stream sediments is unknown. This study compares present-day (2017) contamination trends in the Galena River Watershed to trends reported 25 years ago. A total of 415 sediment/soil samples were collected and analyzed using X-ray florescence spectrometry to determine sediment metal concentrations. The highest concentrations of zinc measured were 23,577 ppm in the channel bed, 19,825 ppm in the channel banks, and 51,273 ppm in tailings. Zinc concentrations averaged 198 ppm within the unmined Madden Branch (n=10), 2,057 ppm within the main branch of the Galena (n=31), 9,569 ppm within the heavily mined Diggings Branch (n=11), and 26,158 ppm in tailings (n=16). Present day contamination trends show little difference compared to 25 years ago. However, stream sediments collected downstream of some large-scale remediation projects have shown significant decreases in Zn concentrations. Nevertheless, even with continued efforts to remediate contaminated sediments in the Galena River, high concentrations will probably persist far into the future.

This book was released on 2017-12-01 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Superfund program of the US Environmental Protection Agency (EPA) was created in the 1980s to address human-health and environmental risks posed by abandoned or uncontrolled hazardous-waste sites. Identification of Superfund sites and their remediation is an expensive multistep process. As part of this process, EPA attempts to identify parties that are responsible for the contamination and thus financially responsible for remediation. Identification of potentially responsible parties is complicated because Superfund sites can have a long history of use and involve contaminants that can have many sources. Such is often the case for mining sites that involve metal contamination; metals occur naturally in the environment, they can be contaminants in the wastes generated at or released from the sites, and they can be used in consumer products, which can degrade and release the metals back to the environment. This report examines the extent to which various sources contribute to environmental lead contamination at Superfund sites that are near lead-mining areas and focuses on sources that contribute to lead contamination at sites near the Southeast Missouri Lead Mining District. It recommends potential improvements in approaches used for assessing sources of lead contamination at or near Superfund sites.

Book Synopsis The Temporal and Spatial Dynamics of Trace Metals in Sediments of a Highly Urbanized Watershed by : D. McCallum
Download or read book The Temporal and Spatial Dynamics of Trace Metals in Sediments of a Highly Urbanized Watershed written by D. McCallum and published by . This book was released on 2006 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Brunette watershed (7200 ha) is located in the urbanized metropolitan area of Greater Vancouver, Canada. It is an area of high traffic density and extensive impervious surfaces (paved roads and roof tops). This watershed provides an excellent area for the study of the spatial and temporal trace metal contamination in sediments. Street surface, stream, and lake sediments were collected over a 25-year period and analyzed for total and acid-extractable trace metals (Cu, Fe, Mn, Pb, and Zn). Lead concentrations in all areas have decreased dramatically, directly as a result of the discontinuation of lead addition to fuels in the 1970s. The mean concentration of total lead in stream sediments has decreased from 230 in 1973 to 134 and 36-66 mg/kg in 1993 and 1997-1998, respectively. Manganese, especially the acid extractable fraction, increased during the early 1990s when MMT replaced tetraethyl lead as an antiknock compound. The 0.5 M HCl extractable manganese in stream sediments has increased from 18 in 1973 to 545 in 1993 and 162-273 mg/kg in 1997-1998. Burnaby Lake, a shallow (Zav=1.0 m, 140 ha) lake, has acted as a sink for trace metal contaminated sediments. Highest trace metal levels are found in surface sediments at the east end of the lake (where Cu, Pb, and Zn were 159, 179, and 529 mg/kg) containing more silt (24 %) and higher organic matter (32.5 %). The sandy delta of Still Creek (silt

Book Synopsis Concentrations and Sources of Trace Metals in Water and Sediments of the South Fork New River, Ashe County, North Carolina, and Their Potential Effects on Aquatic Biota by : Xaviera Watkins

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ore Knob Copper Mine located near Jefferson, North Carolina, operated from 1850 to 1962;mine tailings from the mine were disposed of behind an earthen dam located in the headwaters of Ore Knob Branch, a tributary to Peak Creek. As a result of groundwater contamination, the EPA placed the mine on the National Priority List in 2009. The erosion of mine tailings also released toxic trace metals to Peak Creek, where they were transported to the South Fork New River, an important recreational and ecological resource. The objectives of this study were to determine the source of metals in the South Fork New River and their potential impact(s) on aquatic biota by (1) documenting metal concentrations, and their spatial variations, in water and sediment along the river to locate potential sources, and (2) comparing these metal concentrations to previously developed aquatic effect criteria. Geochemical analyses included the determination of both total and bioavailable concentrations of aluminum, cobalt, copper, iron, and zinc in channel bed sediment as well as their dissolved and total recoverable concentrations in water along a 33km reach of the South Fork New River. Water and sediment samples were also collected from surrounding tributaries, including Peak Creek. Metal concentrations in Peak Creek, below the mine, were relatively high and decreased downstream, indicating that some metals were delivered to the South Fork New River. However, metal concentrations in both water and sediment varied significantly along the river and did not abruptly increase downstream of Peak Creek. These spatial trends suggest that the Ore Knob mine and Peak Creek (which was once devoid of fish) no longer contribute significant quantities of metals to the South Fork New River. Downstream variations in sediment-associated metal concentrations appear to reflect, in part, localized fine-grain sediment deposition, differences in organic carbon content, and the exposure of bedrock outcrops from which sulfidic minerals can be eroded. Comparison of dissolved metal concentrations in water to EPA guidelines found that no sampling sites exceeded acute nor chronic limits. In contrast, numerous (56 %, 94%) of the sampling sites exceeded the NCDEQ total recoverable concentration limits (120 ppb, 7 ppb) for Zn and Cu, respectively. A total of two sites exceeded the threshold effect concentration (TEC) for sediments compiled for Zn by MacDonald et al., whereas 3 sites exceed the TEC for Cu. The various criteria used herein suggest differing potential impacts of the metals on aquatic biota along the South Fork New River. However, the bioavailability of the metals is an important consideration. Dissolved concentrations in water, which indicated limited potential impacts, represent highly bioavailable metals. In contrast, metals attached to sediments both on the channel bed and within the water column may in part, be non-bioavailable, particularly given that the metals are largely derived from sulfidic mineral layers in the bedrock. Thus, the impacts to aquatic biota is likely to be limited.
