Newtown Creek (Pennsylvania)
Newtown Creek, a long tributary of the East River, is an estuary that forms part of the border between the boroughs of Brooklyn and Queens, in New York City. Channelization made it one of the most heavily-used bodies of water in the Port of New York and New Jersey and thus one of the most polluted industrial sites in the United States, containing years of discarded toxins, an estimated of spilled oil, including the Greenpoint oil spill, raw sewage from New York City’s sewer system, and other accumulation from a total of 1,491 sites. Newtown Creek was proposed as a potential Superfund site in September 2009, and received that designation on September 27, 2010. The EPA has delayed its cleanup until 2032. Course The creek begins near the intersection of 47th Street and Grand Avenue on the Brooklyn-Queens border at the intersection of the East Branch and English Kills. It empties into the East River at 2nd Street and 54th Avenue in Long Island City, opposite Bell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Island City
Long Island City (LIC) is a residential and commercial neighborhood on the extreme western tip of Queens, a borough in New York City. It is bordered by Astoria to the north; the East River to the west; New Calvary Cemetery in Sunnyside to the east; and Newtown Creek—which separates Queens from Greenpoint, Brooklyn—to the south. Incorporated as a city in 1870, Long Island City was originally the seat of government of the Town of Newtown, before becoming part of the City of Greater New York in 1898. In the early 21st century, Long Island City became known for its rapid and ongoing residential growth and gentrification, its waterfront parks, and its thriving arts community. The area has a high concentration of art galleries, art institutions, and studio space. Long Island City is the eastern terminus of the Queensboro Bridge, the only non-tolled automotive route connecting Queens and Manhattan. Northwest of the bridge are the Queensbridge Houses, a development of the New ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sunswick Creek
Sunswick Creek is a buried stream located in Astoria and Long Island City, in the northwestern portion of Queens in New York City. It originated to the north of Queensboro Bridge and Queens Plaza in Long Island City, flowing north to the present-day site of the Socrates Sculpture Park in Astoria, and emptying into the East River. The creek was named for a term in the Algonquin language that likely means "Woman Chief" or "Sachem’s Wife." The mouth of the creek was settled in the late 17th century by William Hallet and Elizabeth Fones, who built a milldam at the creek's mouth to create a mill pond. Due to industrialization in Long Island City, the creek became heavily polluted and was covered-over starting in the late 19th century. Course Prior to its burial, Sunswick Creek's source was located close to 21st Street north of what is now the Queensboro Bridge and Queens Plaza, within the Long Island City subsection of Ravenswood. The creek passed north near the current site o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...

Moveable Bridge
A moveable bridge, or movable bridge, is a bridge that moves to allow passage for boats or barges. In American English, the term is synonymous with , and the latter is the common term, but drawbridge can be limited to the narrower, historical definition used in some other forms of English, in which ''drawbridge'' refers to only a specific type of moveable bridge often found in castles . An advantage of making bridges moveable is the lower cost, due to the absence of high piers and long approaches. The principal disadvantage is that the traffic on the bridge must be halted when it is opened for passage of traffic on the waterway. For seldom-used railroad bridges over busy channels, the bridge may be left open and then closed for train passages. For small bridges, bridge movement may be enabled without the need for an engine. Some bridges are operated by the users, especially those with a boat, others by a bridgeman (or bridge tender); a few are remotely controlled using video-cam ...

Long Island Rail Road
The Long Island Rail Road , often abbreviated as the LIRR, is a commuter rail system in the southeastern part of the U.S. state of New York (state), New York, stretching from Manhattan to the eastern tip of Suffolk County, New York, Suffolk County on Long Island. With an average weekday ridership of 354,800 passengers in 2016, it is the List of United States commuter rail systems by ridership, busiest commuter railroad in North America. It is also one of the world's few commuter systems that runs 24/7 year-round. It is Government-owned corporation, publicly owned by the Metropolitan Transportation Authority, which refers to it as MTA Long Island Rail Road. In , the system had a ridership of , or about per weekday as of . The LIRR logo combines the circular MTA logo with the text ''Long Island Rail Road'', and appears on the sides of trains. The LIRR is one of two commuter rail systems owned by the MTA, the other being the Metro-North Railroad in the northern suburbs of the New ...

Montauk Branch
The Montauk Branch is a rail line owned and operated by the Long Island Rail Road in the U.S. state of New York. The branch runs the length of Long Island, 115 miles (185 km) from Long Island City on the west to Montauk on the east. However, in LIRR maps and schedules for public use, the term ''Montauk Branch'' refers to the line east of Babylon; the line west of there is covered by Babylon Branch schedules, and a few Montauk Branch trains operate via the Main Line west of Babylon due to increased track capacities. Route description Lower Montauk left, 200px, Lower Montauk Branch (defunct Richmond Hill station) in 2019 The westernmost portion of the Montauk Branch in Queens, known as the "Lower Montauk," runs between the Long Island City and Jamaica stations, mostly at street level with grade crossings. Just east of the Long Island City station, the abandoned Montauk Cutoff merges with the branch. The Lower Montauk Branch had nine stations, four of which were closed b ...

Sludge
Sludge is a semi-solid slurry that can be produced from a range of industrial processes, from water treatment, wastewater treatment or on-site sanitation systems. For example, it can be produced as a settled suspension obtained from conventional drinking water treatment, as sewage sludge from wastewater treatment processes or as fecal sludge from pit latrines and septic tanks. The term is also sometimes used as a generic term for solids separated from suspension in a liquid; this 'soupy' material usually contains significant quantities of 'interstitial' water (between the solid particles). Sludge can consist of a variety of particles, such as animal manure. Industrial wastewater treatment plants produce solids that are also referred to as sludge. This can be generated from biological or physical-chemical processes. In the activated sludge process for wastewater treatment, the terms "waste activated sludge" and "return activated sludge" are used. In food processing and bevera ...

Urban Runoff
Urban runoff is surface runoff of rainwater, landscape irrigation, and car washing created by urbanization. Impervious surfaces (roads, parking lots and sidewalks) are constructed during land development. During rain , storms and other precipitation events, these surfaces (built from materials such as asphalt and concrete), along with rooftops, carry polluted stormwater to storm drains, instead of allowing the water to percolate through soil. This causes lowering of the water table (because groundwater recharge is lessened) and flooding since the amount of water that remains on the surface is greater.Water Environment Federation Alexandria, VA; an American Society of Civil Engineers Reston, VA [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravity, gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the #Phase and amplitude, phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see ''#Timing, Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal cycle, diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Stagnation
Water stagnation occurs when water stops flowing. Stagnant water can be a major environmental hazard. Dangers Malaria and dengue are among the main dangers of stagnant water, which can become a breeding ground for the mosquitoes that transmit these diseases. Stagnant water can be dangerous for drinking because it provides a better incubator than running water for many kinds of bacteria and parasites. Stagnant water can be contaminated with human and animal feces, particularly in deserts or other areas of low rainfall. Water stagnation for as little as six days can completely change bacterial community composition and increase cell count. Stagnant water may be classified into the following basic, although overlapping, types: * Water body stagnation (stagnation in swamp, lake, lagoon, river, etc.) * Surface and ground waters stagnation * Trapped water stagnation. The water may be trapped in human artifacts (discarded cans, plant pots, tires, dug-outs, roofs, etc.), as well a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combined Sewer
A combined sewer is a type of gravity sewer with a system of pipes, tunnels, pump stations etc. to transport sewage and urban runoff together to a sewage treatment plant or disposal site. This means that during rain events, the sewage gets diluted, resulting in higher flowrates at the treatment site. Uncontaminated stormwater simply dilutes sewage, but runoff may dissolve or suspend virtually anything it contacts on roofs, streets, and storage yards. As rainfall travels over roofs and the ground, it may pick up various contaminants including soil particles and other sediment, heavy metals, organic compounds, animal waste, and oil and grease. Combined sewers may also receive dry weather drainage from landscape irrigation, construction dewatering, and washing buildings and sidewalks. Combined sewers can cause serious water pollution problems during combined sewer overflow (CSO) events when combined sewage and surface runoff flows exceed the capacity of the sewage treatment plant ...
