B-Line Trail
The B-Line Trail is a 3.1 mile multi-use trail in the United States, connecting the downtown area of Bloomington, Indiana, to an outlying neighborhood. The trail connects with the Bloomington Rail Trail which in turn runs into the planned Limestone Greeneay trail. Four plazas are located along the trail, which is fitted with LED lighting. Works of public art including murals and sculpture are located along the trail. There are also fitness stations. The trail runs along a former CSX Railroad bed. It was part of a rail line for more than a century. Pollution from heavy metals and hydrocarbons has been an issue at some parts because of historic cinder and coal ash emissions. The Environmental Protection Agency awarded money for environmental remediation Environmental remediation deals with the removal of pollution or contaminants from environmental media such as soil, groundwater, sediment, or surface water. Remedial action is generally subject to an array of regulatory requireme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Multi-use Trail
A shared-use path, mixed-use path or multi-use pathway is a path which is 'designed to accommodate the movement of pedestrians and cyclists'. Examples of shared-use paths include sidewalks designated as shared-use, bridleways and rail trails. A shared-use path typically has a surface that is asphalt, concrete or firmly packed crushed aggregate. Shared-use paths differ from cycle tracks and cycle paths in that shared-use paths are designed to include pedestrians even if the primary anticipated users are cyclists. The path may also permit other users such as inline skating. Contrastingly, Motorcycles and mopeds are normally prohibited. Shared-use paths sometimes provide different lanes for users who travel at different speeds to prevent conflicts between user groups on high-use trails. Shared-use paths are criticised for creating conflict between different users. Types Bridleways In the UK, cyclists are legally permitted to cycle on bridleways (paths open to horse riders), ...

Bloomington, Indiana
Bloomington is a city in and the county seat of Monroe County, Indiana, Monroe County in the central region of the U.S. state of Indiana. It is the List of municipalities in Indiana, seventh-largest city in Indiana and the fourth-largest outside the Indianapolis metropolitan area. According to the Monroe County History Center, Bloomington is known as the "Gateway to Scenic Southern Indiana". The city was established in 1818 by a group of settlers from Kentucky, Tennessee, the Carolinas, and Virginia who were so impressed with "a haven of blooms" that they called it Bloomington. The population was 79,168 at the 2020 United States census, 2020 census. Bloomington is the home to Indiana University Bloomington, the flagship campus of the Indiana University, IU System. Established in 1820, IU Bloomington has 45,328 students, as of September 2021, and is the original and largest campus of Indiana University.

Limestone Greeneay
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limestone co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LED Light
An LED lamp or LED light bulb is an electric light that produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and can be significantly more efficient than most fluorescent lamps. The most efficient commercially available LED lamps have efficiencies of 200 lumen per watt (Lm/W). Commercial LED lamps have a lifespan many times longer than incandescent lamps. LED lamps require an electronic LED driver circuit to operate from mains power lines, and losses from this circuit means that the efficiency of the lamp is lower than the efficiency of the LED chips it uses. The driver circuit may require special features to be compatible with lamp dimmers intended for use on incandescent lamps. Generally the current waveform contains some amount of distortion, depending on the luminaires’ technology. The LED lamp market is projected to grow from US$75.8 billion in 2020 and increasing to US$160 billion in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CSX Railroad
CSX Transportation , known colloquially as simply CSX, is a Class I freight railroad operating in the Eastern United States and the Canadian provinces of Ontario and Quebec. The railroad operates approximately 21,000 route miles () of track. The company operates as the leading subsidiary of CSX Corporation, a Fortune 500 company headquartered in Jacksonville, Florida. CSX Corporation (the parent of CSX Transportation) was formed in 1980 from the merger of Chessie System and Seaboard Coast Line Industries, two holding companies which controlled a number of railroads operating in the Eastern United States. Initially only a holding company itself, the subsidiaries that made up CSX Corporation were gradually merged, with this process completed in 1987. CSX Transportation formally came into existence in 1986, as the successor of Seaboard System Railroad. In 1999, CSX Transportation acquired approximately half of Conrail, in a joint purchase with competitor Norfolk Southern Railway ...

Heavy Metals
upright=1.2, Crystals of osmium, a heavy metal nearly twice as dense as lead">lead.html" ;"title="osmium, a heavy metal nearly twice as dense as lead">osmium, a heavy metal nearly twice as dense as lead Heavy metals are generally defined as metals with relatively high density, densities, atomic weights, or atomic numbers. The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic number, while a chemist would likely be more concerned with chemical property, chemical behaviour. More specific definitions have been published, but none of these have been widely accepted. The definitions surveyed in this article encompass up to 96 out of the 118 known chemical elements; only mercury, lead and bismuth meet all of them. Despite this lack of agreement, the term (plural or singular) is widely used in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocarbon
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and hydrophobic, and their odors are usually weak or exemplified by the odors of gasoline and lighter fluid. They occur in a diverse range of molecular structures and phases: they can be gases (such as methane and propane), liquids (such as hexane and benzene), low melting solids (such as paraffin wax and naphthalene) or polymers (such as polyethylene and polystyrene). In the fossil fuel industries, ''hydrocarbon'' refers to the naturally occurring petroleum, natural gas and coal, and to their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers. Most anthropogenic (human-generated) emissions of greenhouse gases are carbon di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fly Ash
Fly ash, flue ash, coal ash, or pulverised fuel ash (in the UK) plurale tantum: coal combustion residuals (CCRs)is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases. Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash. In modern coal-fired power plants, fly ash is generally captured by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys. Together with bottom ash removed from the bottom of the boiler, it is known as coal ash. Depending upon the source and composition of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline), aluminium oxide (Al2O3) and calcium oxide (CaO), the main mineral compounds in coal-bearing rock strata.

Environmental Protection Agency
A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment. The term ''environment'' can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK's Environment Agency. Life-environment interaction All life that has survived must have adapted to the conditions of its environment. Temperature, light, humidity, soil nutrients, etc., all influence the species within an environment. However, life in turn modifies, in various forms, its conditions. ...

Environmental Remediation
Environmental remediation deals with the removal of pollution or contaminants from environmental media such as soil, groundwater, sediment, or surface water. Remedial action is generally subject to an array of regulatory requirements, and may also be based on assessments of human health and ecological risks where no legislative standards exist, or where standards are advisory. Remediation standards In the United States, the most comprehensive set of Preliminary Remediation Goals (PRGs) is from the Environmental Protection Agency (EPA) ''Regional Screening Levels'' (RSLs). A set of standards used in Europe exists and is often called the Dutch standards. The European Union (EU) is rapidly moving towards Europe-wide standards, although most of the industrialised nations in Europe have their own standards at present. In Canada, most standards for remediation are set by the provinces individually, but the Canadian Council of Ministers of the Environment provides guidance at a federa ...
