Tar Creek Superfund Site
Tar Creek Superfund site is a United States Superfund site, declared in 1983, located in the cities of Picher and Cardin, Ottawa County, in northeastern Oklahoma. From 1900 to the 1960s lead mining and zinc mining companies left behind huge open chat piles that were heavily contaminated by these metals, cadmium, and others. Metals from the mining waste leached into the soil, and seeped into groundwater, ponds, and lakes. Because of the contamination, Picher children have suffered elevated lead, zinc and manganese levels, resulting in learning disabilities and a variety of other health problems. The EPA declared Picher to be one of the most toxic areas in the United States."Pollution busts Okla. mining town"

Tar is a dark brown or black viscosity, viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic matter, organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat. "a dark brown or black bituminous usually odorous viscous liquid obtained by destructive distillation of organic material (such as wood, coal, or peat)". "tar and pitch, viscous, dark-brown to black substances obtained by the destructive distillation of coal, wood, petroleum, peat and certain other organic materials. " Mineral products resembling tar can be produced from fossil fuel, fossil hydrocarbons, such as petroleum. Coal tar is produced from coal as a byproduct of coke (fuel), coke production. Terminology "Tar" and "pitch (resin), pitch" can be used interchangeably; asphalt (naturally occurring pitch) may also be called either "mineral tar" or "mineral pitch". There is a tendency to use "tar" for more liquid substances and "pitch ...

Commerce, Oklahoma
Commerce is a city in Ottawa County, Oklahoma, United States. The population was 2,473 at the 2010 census, down 6.5 percent from the figure of 2,645 in 2000, and lower than the 2,555 residents it had in 1920. Commerce is included in the Joplin, Missouri metropolitan area. History What became Commerce was land that was part of the Quapaw Indian Agency, allocated in the late 1830s. The Quapaw were removed to the area in the 1830s by the federal government after residing for hundreds of years on the west side of the Mississippi River in what later entered the union as the state of Arkansas. Immigrants arrived and formed a mining camp named Hattonville after Amos Hatton. In 1906, Hatton developed the Emma Gordon zinc and lead mine, whose resources had attracted workers. Starting in 1908, the Oklahoma, Kansas and Missouri Inter-Urban Railway built a line between Miami and Commerce to serve the mining industry. In a series of steps the line was later acquired by the St. Louis– ...

Aquifer
An aquifer is an underground layer of water-bearing, permeable rock, rock fractures, or unconsolidated materials (gravel, sand, or silt). Groundwater from aquifers can be extracted using a water well. Aquifers vary greatly in their characteristics. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude (or ''aquifuge''), which is a solid, impermeable area underlying or overlying an aquifer, the pressure of which could create a confined aquifer. The classification of aquifers is as follows: Saturated versus unsaturated; aquifers versus aquitards; confined versus unconfined; isotropic versus anisotropic; porous, karst, or fractured; transboundary aquifer. Challenges for using groundwater include: overdrafting (extracting groundwater beyond the Dynamic equilibrium, equilibrium yield of the aquifer), groundwater-related subsidence of land, gro ...

Lead Poisoning
Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. The brain is the most sensitive. Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility, and tingling in the hands and feet. It causes almost 10% of intellectual disability of otherwise unknown cause and can result in behavioral problems. Some of the effects are permanent. In severe cases, anemia, seizures, coma, or death may occur. Exposure to lead can occur by contaminated air, water, dust, food, or consumer products. Lead poisoning poses a significantly increased risk to children as they are far more likely to ingest lead indirectly by chewing on toys or other objects that are coated in lead paint. The amount of lead that can be absorbed by children is also higher than that of adults. Exposure at work is a common cause of lead poisoning in adults with certain occupations at particular risk. Diagnosis is typically by ...

Tailing Pond
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which is ...

Quapaw Nation
The Quapaw ( ; or Arkansas and Ugahxpa) people are a tribe of Native Americans that coalesced in what is known as the Midwest and Ohio Valley of the present-day United States. The Dhegiha Siouan-speaking tribe historically migrated from the Ohio Valley area to the west side of the Mississippi River in what is now the state of Arkansas; their name for themselves (or autonym) refers to this migration and to traveling downriver. The Quapaw are federally recognized as the Quapaw Nation. The US federal government forcibly removed them to Indian Territory in 1834, and their tribal base has been in present-day Ottawa County in northeastern Oklahoma. The number of members enrolled in the tribe was 3,240 in 2011. Name Algonquian-speaking people called the Quapaw ''akansa''. French explorers and colonists learned this term from Algonquians and adapted it in French as ''Arcansas''. The French named the Arkansas River and the territory of Arkansas for them. Government The Quapaw Nati ...

National Priorities List
The National Priorities List (NPL) is the priority list of hazardous waste sites in the United States eligible for long-term remedial investigation and remedial action (cleanup) financed under the federal Superfund program. Environmental Protection Agency (EPA) regulations outline a formal process for assessing hazardous waste sites and placing them on the NPL. The NPL is intended primarily to guide EPA in determining which sites are so contaminated as to warrant further investigation and significant cleanup. As of 2022, 1333 sites are on the list, and 43 sites have been proposed for listing. 448 sites have been deleted from the list. Process for listing The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), also known as "Superfund", requires that the criteria provided by the Hazard Ranking System (HRS) be used to make a list of national priorities of the known releases or threatened releases of hazardous substances, pollutants, or contamin ...

Hazard Ranking System
Superfund is a United States federal environmental remediation program established by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). The program is administered by the Environmental Protection Agency (EPA). The program is designed to investigate and clean up sites contaminated with hazardous substances. Sites managed under this program are referred to as "Superfund" sites. There are 40,000 federal Superfund sites across the country, and approximately 1,300 of those sites have been listed on the National Priorities List (NPL). Sites on the NPL are considered the most highly contaminated and undergo longer-term remedial investigation and remedial action (cleanups). The EPA seeks to identify parties responsible for hazardous substances released to the environment (polluters) and either compel them to clean up the sites, or it may undertake the cleanup on its own using the Superfund (a trust fund) and seek to recover those costs from th ...

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. ...

Love Canal
Love Canal is a neighborhood in Niagara Falls, New York, United States, infamous as the location of a landfill that became the site of an enormous environmental disaster in the 1970s. Decades of dumping toxic chemicals harmed the health of hundreds of residents; the area was cleaned up over the course of 21 years in a Superfund operation. In 1890, Love Canal was created as a model planned community, but was only partially developed. In the 1920s, the canal became a dump site for municipal refuse for the city of Niagara Falls. During the 1940s, the canal was purchased by Hooker Chemical Company, which used the site to dump of chemical byproducts from the manufacturing of dyes, perfumes, and solvents for rubber and synthetic resins. Love Canal was sold to the local school district in 1953, after the threat of eminent domain. Over the next three decades, it attracted national attention for the public health problems originating from the former dumping of toxic waste on the grou ...
