Street Sweeper
A street sweeper or street cleaner is a person or machine that cleans streets. People have worked in cities as "sanitation workers" since sanitation and Waste management, waste removal became a priority. A street-sweeping person would use a broom and shovel to clean off litter, animal waste and filth that accumulated on streets. Later, water hoses were used to wash the streets. Street sweepers as machines were created in the 19th century to do the job easier. Today, modern street sweepers are mounted on truck bodies and can vacuum cleaner, vacuum debris that accumulates in streets. History Manual sweeping The need for rubbish to be removed from roads in built-up areas has existed for centuries. Sometimes a local law in a town or city ordered the owner or occupier of each address to clean the length of that road that passed his address. Sometimes when much traffic was horse-drawn vehicles or ridden horses, there were street cleaners who selectively removed manure, horse ...

Street Sweeper In Minneapolis Neighborhood University
A street is a public thoroughfare in a city, town or village, typically lined with Building, buildings on one or both sides. Streets often include pavements (sidewalks), pedestrian crossings, and sometimes amenities like Street light, streetlights or Bench (furniture), benches. A street can be as simple as a level patch of Dirt road, dirt, but is more often pavement (material), paved with a hard, durable surface such as Tarmacadam, tarmac, concrete, cobblestone or brick. It can be designed for both social activity and movement. Originally, the word ''street'' simply meant a paved road (). The word ''street'' is still sometimes used informally as a synonym for ''road'', for example in connection with the ancient Watling Street, but city residents and urban planning, urban planners draw a significant modern distinction: a road's main function is transportation, while streets facilitate public interaction.

Water Quality
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage. It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed. The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extent of water pollution and condition of drinking water. Water quality has a significant impact on water supply and often determines supply options. Impacts on public health Over time, there has been increasing recognition of the importance of drinking water quality and its impact on public health. This has led to increasing protection and management of water quality.

Zero Emission
A zero emission engine, electric motor, motor, process, or other energy source emits no waste products that pollute the environment or disrupt the climate. Zero emission engines Vehicles and other mobile machinery used for transport (over land, sea, air, rail) and for other uses (agricultural, mobile power generation, etc.) contribute heavily to climate change and pollution, so zero emission engines are an area of active research. These technologies almost in all cases include an electric motor powered by an energy source compact enough to be installed in the vehicle. These sources include hydrogen fuel cells, Traction battery, batteries, supercapacitors, and flywheel energy storage devices. In some cases, such as Air engine, compressed air engines, the engine may be mechanical rather than electrical. This mechanical engine is then powered by a passive energy source like compressed air, or a combustible non-polluting gas like hydrogen. The above engines can be used in all vehicles ...

Boschung
Bushong is a surname found mostly in the United States, derived from the surname Boschung found mainly in Switzerland, but also in the Palatinate and other regions in Western Europe. Surname history The American surname, ''Bushong'' and variant ''Bushon'', prior to being ''anglicized'', was the German-Swiss name, ''Boschung''. The spelling was changed after immigration to Colonial America. The immigrants, Hans and Johann Nicholas both arrived as Boschung, Hans in 1731 and Johann Nicholas in 1732.

PM10
Particulate matter (PM) or particulates are microscopic particles of solid or liquid matter suspended in the air. An ''aerosol'' is a mixture of particulates and air, as opposed to the particulate matter alone, though it is sometimes defined as a subset of aerosol terminology. Sources of particulate matter can be natural or anthropogenic. Particulates have impacts on climate and precipitation that adversely affect human health. Types of atmospheric particles include suspended particulate matter; thoracic and respirable particles; inhalable coarse particles, designated PM, which are coarse particles with a diameter of 10 micrometers (μm) or less; fine particles, designated PM, with a diameter of 2.5 μm or less; ultrafine particles, with a diameter of 100 nm or less; and soot. Airborne particulate matter is a Group 1 carcinogen. Particulates are the most harmful form of air pollution as they can penetrate deep into the lungs and brain from blood streams, causing ...

Walk Behind Street Sweeper
Walking (also known as ambulation) is one of the main gaits of terrestrial locomotion among legged animals. Walking is typically slower than running and other gaits. Walking is defined as an "inverted pendulum" gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the usable number of limbs—even arthropods, with six, eight, or more limbs, walk. In humans, walking has health benefits including improved mental health and reduced risk of cardiovascular disease and death. Difference from running The word ''walk'' is descended from the Old English ''wealcan'' 'to roll'. In humans and other bipeds, walking is generally distinguished from running in that only one foot at a time leaves contact with the ground and there is a period of double-support. In contrast, running begins when both feet are off the ground with each step. This distinction has the status of a formal requirement in competitive walking events. For quadrupedal specie ...

Best Practice
A best practice is a method or technique that has been generally accepted as superior to alternatives because it tends to produce superior results. Best practices are used to achieve quality as an alternative to mandatory standards. Best practices can be based on self-assessment or benchmarking. Best practice is a feature of accredited management standards such as ISO 9000 and ISO 14001. Some consulting firms specialize in the area of best practice and offer ready-made templates to standardize business process documentation. Sometimes a best practice is not applicable or is inappropriate for a particular organization's needs. A key strategic talent required when applying best practice to organizations is the ability to balance the unique qualities of an organization with the practices that it has in common with others. Good operating practice is a strategic management term. More specific uses of the term include good agricultural practices, good manufacturing practice, good labora ...

Stormwater Runoff
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to '' channel runoff'' (or ''stream flow''). It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry human-made cont ...

Pollutant
A pollutant or novel entity is a substance or energy introduced into the environment that has undesired effect, or adversely affects the usefulness of a resource. These can be both naturally forming (i.e. minerals or extracted compounds like oil) or anthropogenic in origin (i.e. manufactured materials or byproducts). Pollutants result in environmental pollution or become of public health concern when they reach a concentration high enough to have significant negative impacts. A pollutant may cause long- or short-term damage by changing the growth rate of plant or animal species, or by interfering with resources used by humans, human health or wellbeing, or property values. Some pollutants are biodegradable and therefore will not persist in the environment in a long term. However, the degradation products of some pollutants are themselves pollutants such as DDE and DDD produced from the degradation of DDT. Pollution has widespread negative impact on the environment.
