Indoor air quality (IAQ) is the air quality within buildings and structures. Poor indoor air quality due to indoor air pollution is known to affect the health, comfort, and well-being of building occupants. It has also been linked to sick building syndrome, respiratory issues, reduced productivity, and impaired learning in schools. Common pollutants of indoor air include: secondhand tobacco smoke, air pollutants from indoor combustion, radon, molds and other allergens, carbon monoxide, volatile organic compounds, legionella and other bacteria, asbestos fibers, carbon dioxide, ozone and particulates.
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle. It often disperses downwind in a pattern called an exhaust plume.
Volatile organic compounds (VOCs) are organic compounds that have a high vapor pressure at room temperature. They are common and exist in a variety of settings and products, not limited to house mold, upholstered furniture, arts and crafts supplies, dry cleaned clothing, and cleaning supplies. VOCs are responsible for the odor of scents and perfumes as well as pollutants. They play an important role in communication between animals and plants, such as attractants for pollinators, protection from predation, and even inter-plant interactions. Some VOCs are dangerous to human health or cause harm to the environment, often despite the odor being perceived as pleasant, such as "new car smell".
A gas stove is a stove that is fuelled by flammable gas such as natural gas, propane, butane, liquefied petroleum gas or syngas. Before the advent of gas, cooking stoves relied on solid fuels, such as coal or wood. The first gas stoves were developed in the 1820s and a gas stove factory was established in England in 1836. This new cooking technology had the advantage of being easily adjustable and could be turned off when not in use. The gas stove, however, did not become a commercial success until the 1880s, by which time supplies of piped gas were available in cities and large towns in Britain. The stoves became widespread on the European Continent and in the United States in the early 20th century.
The Barnett Shale is a geological formation located in the Bend Arch-Fort Worth Basin. It consists of sedimentary rocks dating from the Mississippian period in Texas. The formation underlies the city of Fort Worth and underlies 5,000 mi2 (13,000 km2) and at least 17 counties.
Ponder Independent School District is a public school district based in Ponder, Texas, United States.
Lantana is an upscale census-designated place (CDP) and planned community originally developed by Republic Property Group, 8 miles (13 km) south of Denton in unincorporated Denton County, Texas, United States. The population of the CDP at the 2010 census was 6,874. Lantana had 3,274 occupied homes as of December 31, 2015, with an estimated population of 10,641. Lantana shares the 76226 ZIP code of Argyle. Approximately one quarter of the populace have an annual household income of greater than $150,000, with 34% having incomes from $75,000-$150,000. Almost half of the Lantana population has a bachelor's degree or higher. In 2004, 2006, 2011 and 2012, Lantana won the People's Choice Award for Community of the Year at the Dallas Homebuilders Association McSAM Awards. Lantana hosts regular community events, such as outdoor music presentations in the parks, chili cook offs, festivals, picnics, and other similar functions for its residents.
Paloma Creek is a master-planned community in northeastern Denton County, Texas, United States. The community is listed by the U.S. Census Bureau as two separate census-designated places, "Paloma Creek" and "Paloma Creek South", separated by U.S. Highway 380. As of the 2010 census, the Paloma Creek CDP had a population of 2,501, while Paloma Creek South had a population of 2,753. As of 2022, the HOA currently estimates the population to be approximately 20,000.
Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health. Research has determined that human health is affected. A number of instances with groundwater contamination have been documented due to well casing failures and illegal disposal practices, including confirmation of chemical, physical, and psychosocial hazards such as pregnancy and birth outcomes, migraine headaches, chronic rhinosinusitis, severe fatigue, asthma exacerbations, and psychological stress. While opponents of water safety regulation claim fracking has never caused any drinking water contamination, adherence to regulation and safety procedures is required to avoid further negative impacts.
Toxic hotspots are locations where emissions from specific sources such as water or air pollution may expose local populations to elevated health risks, such as cancer. These emissions contribute to cumulative health risks of emissions from other sources nearby. Urban, highly populated areas around pollutant emitters such as old factories and waste storage sites are often toxic hotspots.
In an oil and gas production, flash-gas is a spontaneous vapor that is produced from the heating or depressurization of the extracted oil mixture during different phases of production. Flash evaporation, or flashing, is the process of volatile components suddenly vaporizing from their liquid state. This often happens during the transportation of petroleum products through pipelines and into vessels, such as when the stream from a common separation unit flows into an on-site atmospheric storage tank. Vessels that are used to intentionally “flash” a mixture of gas and saturated liquids are aptly named "flash drums." A type of vapor-liquid separator. A venting apparatus is used in these vessels to prevent damage due to increasing pressure, extreme cases of this are referred to as boiling liquid expanding vapor explosion (BLEVE).
Emmell's Septic Landfill (ESL) is a landfill in Galloway Township, New Jersey and takes up about 38 acres of space. The landfill was in operation from 1967 until 1979. ESL disposed of liquid and solid waste including many chemicals such as volatile organic compounds (VOCs), Polychlorinated Biphenyls (PCBs), Trichloroethene and Vinyl chloride which all had their own effect on the environment and community. These chemicals affected the groundwater required millions of dollars to reconstruct the groundwater pathways and provide clean water to residents. The landfill holds a Hazardous Ranking Score of a 50/100, qualifying for the Superfund National Priority List. In August 1999, the state acknowledged the site's contamination and held town meetings and provided research upon the site such as groundwater samples. In July 1997, a sitewide investigation was called upon by the United States Environmental Protection Agency. In total the clean up was estimated to cost $5 million to fund this superfund site, and a grant of $3.9 million was given by the Federal Government under the Recovery Act Funding (Previti). Today, the project is still ongoing however, greatly improved since the landfill was discovered.
The Chemical Control Corporation superfund site is located at 22 South Front St. Elizabeth, New Jersey. Once a marsh, the 2-acre (0.81 ha) area next to the Elizabeth River is primarily flat land slightly above sea-level. The company, Chemical Control Corporation, worked as a hazardous waste disposal plant from 1970 until its condemnation in 1979. Before the April 21, 1980 fire, it was reported that over 50,000 drums of chemicals, including dioxin, benzene, cyanide, toluene, ethylene dichloride and more, were present on the site. State intervention was taken prior to the fire, but it became a matter of national intervention following the fire due to the level of contamination that impacted the environment and community. Cleanup operations have been underway since the early 1980s. The Environmental Protection Agency is considering removing the site from the National Priorities List because of the extensive cleanup that has been done.
