Geochemical Modeling of Iron and Aluminum Precipitation During Mixing and Neutralization of Acid Mine Drainage
minerals Article Geochemical Modeling of Iron and Aluminum Precipitation during Mixing and Neutralization of Acid Mine Drainage Darrell Kirk Nordstrom U.S. Geological Survey, Boulder, CO 80303, USA; [email protected] Received: 21 May 2020; Accepted: 14 June 2020; Published: 17 June 2020 Abstract: Geochemical modeling of precipitation reactions in the complex matrix of acid mine drainage is fundamental to understanding natural attenuation, lime treatment, and treatment procedures that separate constituents for potential reuse or recycling. The three main dissolved constituents in acid mine drainage are iron, aluminum, and sulfate. During the neutralization of acid mine drainage (AMD) by mixing with clean tributaries or by titration with a base such as sodium hydroxide or slaked lime, Ca(OH)2, iron precipitates at pH values of 2–3 if oxidized and aluminum precipitates at pH values of 4–5 and both processes buffer the pH during precipitation. Mixing processes were simulated using the ion-association model in the PHREEQC code. The results are sensitive to the solubility product constant (Ksp) used for the precipitating phases. A field example with data on discharge and water composition of AMD before and after mixing along with massive precipitation of an aluminum phase is simulated and shows that there is an optimal Ksp to give the best fit to the measured data. Best fit is defined when the predicted water composition after mixing and precipitation matches most closely the measured water chemistry. Slight adjustment to the proportion of stream discharges does not give a better fit. Keywords: geochemical modeling; acid mine drainage; iron and aluminum precipitation; schwertmannite; basaluminite 1. -
Highway Conditions Introduction
Chapter 4 Highway Conditions Introduction The Ebbetts Pass National Scenic Byway (NBS) began as a trail that American Indians most likely used for trade and a hunting access route, and was later utilized by fur trappers. By the early to mid 1800’s pioneers and miners crossed over the pass. With the discovery of silver and the demand for more supplies to be delivered to the region, so came improvements to the road. Today, the highway itself is managed and maintained by the California Department of Transportation (CalTrans). The road twists you further into the mountains narrowing with no centerline near Lake Alpine as it separates both the Carson-Iceberg and Mokelumne Wildernesses, luring the traveler farther away from society. The journey takes one both physically and psychologically closer to wildness. Beyond the crest of Ebbetts Pass, the descent winds through a rugged volcanic landscape overlooking the canyons below. This asphalt ribbon transitions back to a distinct, 2-lane highway with a centerline when you reach the floor of Silver Creek, just east of Silver Creek Campground. This portion of the byway is steep, narrow, and windy, and is not suitable for semi trucks, buses, and most Recreational Vehicles (RV’s). It is best left for smaller vehicle travel. Average Daily Traffic CalTrans collects data annually that reflects the number of vehicles that travel along Highway 4 in a given month. This data is compiled into average annual daily traffic counts (AADT). AADT numbers are calculated using electronic highway counters, determining the yearly figure and dividing by 365 days/year. -

Calvin, Ph.D., Advisor Simon R. Poulson, Ph.D., Committee Member Glenn C. Miller, Ph.D., Graduate School Representative David W. Zeh, Ph.D., Dean, Graduate School December, 2015 i Abstract: Acid mine drainage (AMD) resulting from the oxidation of sulfides in mine waste is a major environmental issue facing the mining industry today. Open pit mines, tailings ponds, ore stockpiles, and waste rock dumps can all be significant sources of pollution, primarily heavy metals. These large mining-induced footprints are often located across vast geographic expanses and are difficult to access. With the continuing advancement of imaging satellites, remote sensing may provide a useful monitoring tool for pit lake water quality and the rapid assessment of abandoned mine sites. This study explored the applications of laboratory spectroscopy and multi-season hyperspectral remote sensing for environmental monitoring of mine waste environments. -
5.1 Historic Period Human Interaction with the Watershed
Upper Carson River Watershed Stream Corridor Assessment 5. Human Interaction With the Watershed 5.1 Historic Period Human Interaction With the Watershed The purpose of this section is to summarize human activities that have had some effect on the Carson River watershed in Alpine County, California. Regional prehistory and ethnography are summarized by Nevers (1976), Elston (1982), d’Azevedo (1986), and Lindstrom et al. (2000). Details of regional history can be found in Maule (1938), Jackson (1964), Dangberg (1972), Clark (1977), Murphy (1982), Marvin (1997), and other sources. A book published by the Centennial Book Committee (1987) contains an excellent selection of historic photographs. Particularly useful is a study on the historical geography of Alpine County by Howatt (1968). 5.1.1 Prehistoric Land Use Human habitation of the Upper Carson River Watershed extends thousands of years back into antiquity. Archaeological evidence suggests use of the area over at least the last 8,000 to 9,000 years. For most of that time, the land was home to small bands of Native Americans. Their number varied over time, depending on regional environmental conditions. For at least the last 2,000 years, the Washoe occupied the Upper Carson River Watershed. Ethnographic data provides clues as to past land use and land management practices (see extended discussions in Downs 1966; Blackburn and Anderson 1993; Lindstrom et al. 2000; Rucks 2002). A broad range of aboriginal harvesting and hunting practices, fishing, and camp tending would have affected the landscape and ecology of the study area. Shrubs such as service berry and willow were pruned to enhance growth. -
