Question: The town of Cardin, Oklahoma is located within the Tar Creed Superfund site causing toxic areas and therefore reducing the population to what number in November 2010?

full_context: Document 1: Cardin, Oklahoma: Cardin is a ghost town in Ottawa County, Oklahoma, United States. The population was 150 at the 2000 census, but plummeted to 3 at the 2010 census in April 2010.

Document 2: Tar Creek (film): Tar Creek is a 2009 feature-length environmental documentary about the Tar Creek Superfund Site, which at one time was considered the worst environmental disaster in the United States. It was directed Matt Myers, who also wrote the film's script and served as its narrator.
Document 3: McCurtain County, Oklahoma: McCurtain County is located in the southeastern corner of the U.S. state of Oklahoma. As of the 2010 census, the population was 33,151. Its county seat is Idabel. It was formed at statehood from part of the earlier Choctaw Nation in Indian Territory. The name honors an influential Choctaw family that lived in the area.

It was founded between 1824 and 1831, by people of the Choctaw Indian tribe who were forced to leave their homes in the Southeastern United States and relocate in an area designated in for their resettlement in Indian Territory. The community was named for Joseph Doak, co-owner of the local trading post.

It is now a ghost town and an archaeological preservation site.
Document 5: Iron Mountain Mine: Iron Mountain Mine, also known as the Richmond Mine at Iron Mountain, is a mine near Redding in Northern California, US. Geologically classified as a "massive sulfide ore deposit", the site was mined for iron, silver, gold, copper, zinc and pyrite intermittently from the 1860s until 1963. The mine is the source of extremely acidic mine drainage which also contains large amounts of zinc, copper and cadmium. One of America's most toxic waste sites, it has been listed as a federal Superfund site since 1983.
Document 6: List of Superfund sites in Nevada: This is a list of Superfund sites in Nevada designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations. These locations are known as Superfund sites, and are placed on the National Priorities List (NPL). The NPL guides the EPA in "determining which sites warrant further investigation" for environmental remediation. As of November 29, 2010, there was one Superfund site on the National Priorities List in Nevada, with no further sites proposed for addition. No site has yet been removed from the list.
Document 7: FMC Corporation (Fridley Plant): The 18-acre FMC Corporation (Fridley Plant) is a United States Environmental Protection Agency Superfund site located in Anoka County, Minnesota, several hundred feet east of the Mississippi River. Solvents, paint sludge, and plating wastes were generated and disposed of in an on-site dump from the 1940s until 1969. Minnesota Pollution Control Agency (MPCA) staff sampled site surface and groundwater in the early 1980s and confirmed that ground and surface water were contaminated by industrial solvents. In the 1980s, solvents from the site were detected in the city of Minneapolis drinking water system intake that is located downgradient of where the FMC site groundwater contaminant plume enters the river.
Document 8: Exide lead contamination: The Exide lead contamination, in southeast Los Angeles County, California, United States, came from a battery recycling plant that emitted lead, arsenic and other dangerous pollutants over decades that contaminated as many as 10,000 homes in half a dozen working-class, Latino communities near the plant. Exide Technologies, owner of the lead-acid battery smelter located in Vernon, agreed in 2015 to close the facility while the massive cleanup of the contaminated soil will take years and cost hundreds of millions of dollars. The residents have expressed outrage over the failure of state regulators to act as the plant was allowed to operate without a full permit while documented violations were occurring. The Department of Toxic Substances Control, which allowed the plant to operate, is in charge of the cleanup and is finding that the many residents do not trust them. The residents must give them permission to test the soil around their home yet many feel betrayed by this government agency.
Document 9: Tri-State district: The Tri-State district was an historic lead-zinc mining district located in southwest Missouri, southeast Kansas and northeast Oklahoma. The district produced lead and zinc for over 100 years. Production began in the 1850s and 1860s in the Joplin - Granby area of Jasper and Newton counties of southwest Missouri and continued until the closure of the Picher, Oklahoma mines in 1967. The tri-state district includes three mining-related Superfund sites: the Tar Creek Superfund site in Oklahoma, and two others in Missouri and Kansas.
Document 10: Mill Creek, Oklahoma: Mill Creek is a town in Johnston County, Oklahoma, United States. The population was 319 at the 2010 census, a loss from 340 at the 2000 census. Mill Creek Community is an unincorporated area of Johnston County that surrounds the town and claims to have about 1,000 residents, including those that live within the town limits.

Document 12: Koppers Co., Inc. (KCI) Superfund Site: The Koppers Co., Inc. (KCI) Superfund Site is one of three Superfund sites in Oroville, California, along with Louisiana Pacific Sawmill and Western Pacific Railyard. The KCI Superfund Site is a 200-acre site which served as a wood treatment plant for 50 years. Wood was treated with many chemicals to prevent wood deterioration. The accumulation of these chemicals from spills, fires, and uses has caused this site to be contaminated with hazardous waste material. Due to soil and groundwater contamination, the site was placed on the National Priorities List in 1984 for remedial action plans to clean up the site to protect surrounding residential areas concerning environmental and human health risks.
Document 13: Boggy Depot, Oklahoma: Boggy Depot is a ghost town and Oklahoma State Park that was formerly a significant city in the Indian Territory. It grew as a vibrant and thriving town in present-day Atoka County, Oklahoma, United States and became a major trading center on the Texas Road and the Butterfield Overland Mail route between Missouri and San Francisco. After the American Civil War when the MKT Railroad came through, it bypassed Boggy Depot and the town began a steady decline. It was soon replaced by Atoka as the chief city in the area. By the early 20th century, all that remained of the community was a sort of ghost town.
Document 14: Tar Creek Superfund site: Tar Creek Superfund site is a United States Superfund site, declared 1983, located in the cities of Picher and Cardin, Northeastern Oklahoma. From 1900 to the 1960’s lead mining  and zinc mining companies left open Chat piles behind until the present day. The dust has blown around the city containing these metals, cadmium, and others. The metals have also seeped into groundwater, ponds, and lakes, many of which still are used by children for swimming. Elevated lead, zinc and manganese levels in Picher children have led to learning disabilities and other problems. The EPA declared Picher to be one of the most toxic areas in the United States.
Document 15: Cassiar, British Columbia: Cassiar is a ghost town in British Columbia, Canada. It was a small company-owned asbestos mining town located in the Cassiar Mountains of Northern British Columbia north of Dease Lake. After forty years of operation, starting in 1952, the mine was unexpectedly forced to close in 1992. The closure was driven by a combination of factors including diminished demand for asbestos and expensive complications faced after converting from an open-pit mine to an underground mine. Most of the contents of the town, including a few houses, were sold off and trucked away. Most of the houses were bull-dozed and burned to the ground. The mill was briefly reactivated in 1999 by Cassiar Chrysotile Inc which had a reclamation permit to clean up the site. 11,000 tons of asbestos were exported before the mill burned down on Christmas Day of 2000, effectively halting all production. Today the streets are bare and flowers bloom where the houses once stood. Residents living between the townsite and the Stewart-Cassiar Highway, and on the highway itself, who originally obtained phone service from the Cassiar exchange, were moved to the nearby Good Hope Lake exchange in fall 2006 and the Cassiar exchange shut down.
