The document discusses a railroad project in the 1920s that moved train tracks and built an access road over Native Springs, filling the area with dirt and rock without testing for toxicity. A 200 foot by 6 foot concrete "trail" was constructed, cutting through wetlands and destroying tree roots, causing erosion and water pollution. In 2010, an excavator was observed placing large, heavy rocks in a fragile pool bed, lifting them with pressure that drove into the substrate, further damaging the area. The River Exchange organization was granted funds to restore the Headwater Springs but the project appears to have caused further destruction rather than restoration.

Restoration of-the-headwaters-2010-09-01
The document discusses concerns about restoration work being done by the Railroad Exchange on Native Springs and the river. Specifically, it notes that fill materials used to build an access road and place metal structures were not tested for toxicity. Additionally, the organization did not conduct tests to determine if the work impacted wetland areas. The excavation work destroyed tree roots and is causing erosion and water pollution. The document urges contacting the Railroad Exchange to address these issues.
Headwaters bolger-2010-08-30
The document discusses the restoration of Headwater Springs. It describes how the railroad in the 1920s built tracks and roads over native springs, placing fill dirt and rock. In 2002, an organization called River Exchange was granted funds to restore the Headwater Springs after a railroad disaster poisoned a river. They began excavator work in September to remove the toxic railroad fill and rusting infrastructure. The document urges getting the restoration right and contacting River Exchange for more information and resources.

Ravine Alliance
This document discusses the importance of natural fluvial geomorphic processes for maintaining healthy ravine ecosystems. It uses several examples of ravines in the Highland Moraine region to illustrate the benefits of allowing natural erosion and sediment movement. Ravines that are confined or have sediment transport disrupted lose their ability to support diverse habitats and sensitive species. In contrast, ravines like Rosewood that are unaltered retain dynamic stability through natural cutting, filling, and transport processes - sustaining high biodiversity potential.
Jennings tdec stream small
The document provides an overview of streams and stream restoration. It defines what a stream is and discusses fluvial geomorphology and forms. Key concepts covered include meandering streams, bankfull stage, stream ecosystems and functions. The effects of urbanization on streams and symptoms of "urban stream syndrome" are outlined. Factors that contribute to a healthy stream are identified, such as bed stability, sediment transport balance, in-stream habitat, bank stability, riparian buffers, active floodplains, and watershed health. Stream restoration planning and components involving channel morphology, floodplain structure, hydrologic analysis, in-stream structures, habitats and vegetation are summarized. Case studies of stream restoration projects are presented.
2. apllied-hydrogeology-fetter- 2--315-324
The document discusses lithified sedimentary rocks and their impact on groundwater flow. Complex stratigraphy, such as interfingering rock units, can make groundwater exploration challenging. Folds and faults can create complex hydrogeologic systems, acting as barriers or conduits to flow depending on their composition. Clastic sedimentary rocks have permeability influenced by grain size, sorting, and cementation, with fractures increasing permeability. Fractures near the surface are important for bypassing low-permeability layers and recharge.

This document discusses enhancing ecosystem services through sediment retention in Phewa Lake, Nepal. Phewa Lake provides valuable ecosystem services but is threatened by heavy sedimentation. The study found that agricultural activities are major contributors to sedimentation. Payment for ecosystem services could help reduce sedimentation by improving farming practices and planting vegetation. Establishing organizations to manage payments between upstream communities and downstream beneficiaries could make a sediment retention PES program feasible for Phewa Lake.

The key components of restoration projects are then outlined, including reconfiguring the channel and floodplain connection, installing in-stream structures, stabilizing streambanks, establishing riparian buffers, managing stormwater, improving stream crossings, monitoring and maintenance, and providing public access and education. Specific restoration techniques are illustrated with photos from case studies. The document emphasizes the importance of designing projects based on reference streams and ensuring projects are properly constructed and maintained.
Madison fish passage conference presentation 2! Razvan Voicu, Eric Kay!
The document presents case studies that propose practical solutions for restoring fish passage on the Crisul Repede River in Romania. Currently, discharge sills and small dams stop fish migration. The proposed solutions include installing a rubber canal fish passage system upstream of one discharge sill and a concrete ramp fishway system upstream of another. Both proposed solutions aim to provide a cost-effective way of allowing fish to pass through the barriers while requiring minimal human intervention.

World class hydrocarbon accumulations are often found in ancient basins containing evaporites. The distribution of carbonate and evaporite facies provides important seals and traps for hydrocarbon storage. Evaporites are deposited during sea level lowstands, forming thick basin-center deposits that later provide regional seals. Large evaporite deposits occur when tectonic, climate, and basin conditions restrict marine waters and enable net evaporation. Saline giants are found in continental interior sag basins, post-orogenic foreland basins, and late-stage rift basins. Facies transitions between carbonates and evaporites within sequences can also generate hydrocarbon traps and seals.
Processes and Landforms of the Willamette River and Floodplain
This document summarizes current understanding of geomorphic processes shaping the Willamette River floodplain and identifies key knowledge gaps. It outlines a proposed study to better understand landforms, channel processes, gravel transport, vegetation succession, and their relationships. The study would create detailed habitat and landform maps, evaluate gravel supply and transport, and assess channel and floodplain evolution over time to address major questions about how flows shape habitats and the balance between gravel supply and transport.
McKechnie and Annesley GSA 2014 Presentation
This document summarizes research on uranium-thorium-rare earth element mineralized granitic pegmatites from the Fraser Lakes Zone B region. The pegmatites formed from partial melting of metasedimentary crustal rocks during peak metamorphism around 1.8 billion years ago. The melts migrated and crystallized in the middle crust, concentrating along structural features like the contact between older gneisses and folded metasedimentary rocks. Two types of pegmatites are distinguished based on their mineralogy and inferred source compositions. The mineralization shares similarities with other granite-hosted uranium deposits and may have provided a source of uranium for nearby unconformity-type deposits in the Athabasca
McKechnie et al. GAC-MAC 2013 Presentation
This document describes a petrogenetic model for uranium mineralization hosted in granitic pegmatites in the Wollaston Domain of Saskatchewan. Partial melting of metasedimentary rocks during peak metamorphism generated uranium-rich melts. These melts migrated along structural pathways and crystallized in the middle crust, forming the granitic pegmatites. The mineralization shows structural control along the contact between Archean gneisses and younger metasediments, as well as within antiformal fold noses. Differences in uranium concentration between pegmatite groups relate to source composition and degree of melting/fractional crystallization. The deposit shares similarities with other granitoid-hosted uranium deposits and
Hop and Providence rivers restoration!
The document discusses ecological restoration efforts along the Hop River and Providence River. For the Hop River, the banks were stabilized with vegetation and coconut fiber rolls, but these were later destroyed due to the sandy bank composition. The banks will now be restored using a bamboo structure pillar method to support the banks. For the Providence River, the complete concreting had led to pollution and biodiversity loss. The proposal is to construct a rectangular bamboo riverbed and two treated bamboo platforms downstream of the first bridge to restore riparian habitat.
Testing and Implementation of AMD Mitigation, Alum Gulch-Flux Canyon, Cox Gul...
The document summarizes a plan to mitigate acid mine drainage (AMD) and heavy metals in several tributaries in southeastern Arizona that flow into Sonoita Creek and Patagonia Lake. The plan involves installing gabion retaining wall structures and stream bed footers containing zeolite materials downstream of mine discharge points to raise pH and reduce metals like zinc, cadmium, lead, and copper. Water quality and biological monitoring will occur before and after installation to evaluate effectiveness. Zeolites are effective at absorbing metals and raising pH, as shown in previous studies. The structures are intended to last 5-10 years before material replacement depending on runoff conditions.

2) Created a 3D model of the Gold King Mine underground workings to investigate possible connections explaining high discharge volumes.
3) Presented their comparative analysis and findings to the public to provide a more complete understanding of the mine and varying metal concentrations in streams.
Geochemical anomalies in drainage sediments
The document discusses geochemical anomalies found in various types of drainage sediments that can be used for mineral exploration, including spring/seepage sediments, active stream sediments, flood plain sediments, lake sediments, and marine sediments. It explains that drainage sediments provide a sampling medium and anomalies may form from elements precipitating or being eroded, transported, and deposited. The document also notes that lake and marine sediments can indicate mineral deposits based on elements incorporated in sediments or precipitates.

False Promises: Water Quality Predictions Gone Wrong Large Mines and Water Po...No to mining in Palawan
The document discusses 10 examples of mines where government agencies and mining companies predicted little or no impact to water quality from the mines, but significant impacts occurred. In many cases, the mines generated acid mine drainage and heavy metal pollution in nearby streams at levels that harm aquatic life. Several mines filed for bankruptcy after closing, leaving state governments with high costs for long-term water treatment to address the ongoing pollution problems caused by the mines.Fore Site Summary Report
1. The document summarizes a study of 34 restoration sites within the Fore River Sanctuary in Portland, Maine. Sites were assessed and categorized based on degradation source and potential steward.
2. Major sources of degradation included erosion from an unstable railroad bed causing wetland loss and filling, as well as clearing for utility infrastructure which restricted tides and caused pollution. Nine tidal restrictions were documented.
3. The two local stewardship organizations could address many issues created by the railroad and utilities, such as building bridges over trails to restore tides. Educating locals on stewardship was also recommended.
STEEL SLAG LEACHATE
This document provides an overview of steel slag leachate and its impact on the environment using the US Republic Steel slag piles near Lorain, Ohio as a case study. It describes how rainwater percolating through slag piles becomes highly alkaline leachate that can mobilize heavy metals. The leachate from the US Republic piles is polluting nearby pools and waterways. The document recommends conducting a risk assessment, holding the property owner responsible, and capping the piles to collect leachate before a planned bike trail is opened on the site.
Paleoflow Final draft
- 11,700 years ago, the Wisconsinian glacier receded from North America, ending the Pleistocene epoch and leaving behind glacial deposits.
- The researcher examined gravel pits in Crawford County, PA to observe bedding and measure the strike and dip of clasts to determine the paleoflow direction of ancient glacial rivers.
- At 5 of the 35 gravel pits studied, clast imbrications indicated consistent southward paleoflow, suggesting present drainage patterns are inherited from Pleistocene systems. However, too few sites showed visible imbrications to construct an accurate paleoflow map.

Coastal Landscapes and How they Must Adapt to Climate Change
Presentation by Marcha Johnson, NYC Department of Parks and Recreation, at Enterprise Community Partners, New York City, 20 September 2016
GEOSCIENCE 08 Carey et al 437-444
Three arrays of MacroRhizone pore water samplers were deployed at the abandoned Devon Great Consols mine site to investigate water-substrate interactions and potential environmental contamination. Samples were taken from three distinct tailings types - copper, tin, and arsenic tailings - deposited at different stages of the mine's history. Pore water compositions varied significantly between tailings types, with copper tailings highest in copper, aluminum, and manganese, tin tailings highest in tin but lowest in other metals, and arsenic tailings highest in arsenic, sodium, and strontium but lowest in copper. This suggests ongoing geochemical processes influence pore water compositions differently in each tailings type. SEM-EDX analysis showed

Mosquito Poster Final
The document summarizes the geologic history of Mosquito Lake State Park in Ohio. The park was shaped by glacial activity during the Pleistocene, which deposited drift material over older Devonian bedrock. The geology includes three distinct glacial features - a portion of the Defiance End Moraine, ground moraine forming the western park's flat surface, and lacustrine deposits from a former lake. The bedrock consists of Devonian sandstones and shales deposited in marine environments. Multiple glacial advances covered the area with till during the Wisconsinan Glacier before retreating.
Moving the Copper
Moving a 28 ton boulder of pure copper is quite an adventure. This is the story of why on earth anyone would want to move such a beast! AAPS/Ancient Artifact Preservation Society and hundreds of friends want to save it from being sold for commercial melt down. As far as we know this is the largest natural glacial "float" copper in the world, and it's a specimen worth saving.
The Vale Brazilian Dam Collapse: An Ethical and Engineering Disaster
Vale S.A. is the largest iron ore mining company in the world. On January 25, 2019, Dam1 of Vale’s
Corrego do Feijao iron-ore mine in Brazil collapsed. The dam was built upstream on a mountain in order to contain
mining waste or tailings, which are made up of dirt, rocks and bits of ore that are dumped into a dam reservoir. The
mining waste was estimated to be travelling as fast as 50 miles an hour downhill toward the city of Brumadinho. The
mining waste killed 270 people within minutes, and it is the deadliest mining disaster of its type in more than 50 years.
Mine sediment from the dam was found as far away as 119 miles from the dam.
There were several causes for the dam’s failure including: the use of cheap materials, Vale’s managers ignoring
warnings of structural problems, and monitoring equipment that was no longer working. Both Vale and its safety
inspector TUV SUD are under criminal investigations for their actions leading up to the dam collapse.
Beach Road, Porous Pavement and Then Some
This document summarizes a presentation on a project to reconstruct a 1-mile section of Beach Road in Lake George, NY using porous asphalt pavement. The road was experiencing drainage and water quality issues. The project incorporated heavy-duty porous asphalt and stormwater treatment structures to address these issues. It established testing and maintenance protocols to ensure proper performance of the porous pavement system over time. The project has significant implications as one of the first applications of porous pavement to a higher traffic road.
Project report on water jet system
The document provides information about the history and working of water jet cutters. It discusses how water jet cutting originated in the 1950s and evolved over time with improvements to nozzle design, addition of abrasives, and development of high pressure pumps and motion control systems. The key developments include using abrasives to cut hard materials in the 1930s, reliable high pressure pumps in the 1960s, precise motion control in the 1990s, and modern water jet cutters that can switch between pure water and abrasive water jets. It then explains the basic working of water jet cutters, including how water is pressurized up to 50,000 psi using intensifier pumps and exits the nozzle or mixing tube at very high speeds to cut materials
love canal tragedy
Love Canal incident is remembered as a "national symbol of a failure to exercise a sense of concern for future generations", as retold by, New York State Health Department Commissioner David Axelrod.....it is an example of ground water pollution
