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?
Context: The Stringfellow Acid Pits are a toxic waste dump, and a Superfund site, located in Riverside County, California, United States, just north of the neighborhood of Glen Avon, California.  The site became the center of national news coverage in the early 1980s, in part because it was considered one of the most polluted sites in California, and because it became linked with mismanagement and scandal in the U.S. Environmental Protection Agency. The 70-acre Burlington Northern (Brainerd/Baxter Plant) is a United States Environmental Protection Agency (EPA) Superfund site located on the boundary between the cities of Brainerd and Baxter, in Crow Wing County, Minnesota, in an area south of the Paul Bunyan State Trail and State Highway 210 and north of Florence Street.  The Mississippi River flows approximately 3,000 feet east of the site.  The site is bordered by commercial and light industrial areas to the north and southwest and by residential areas to the south and southeast. 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. 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.  The town is located within the Tar Creek Superfund site; the vast majority of its residents accepted federal buyout offers, and the town's population dropped to zero in November 2010. The Fernald Feed Materials Production Center (commonly referred to simply as Fernald or later NLO) is a Superfund site located within Crosby Township in Hamilton County, Ohio, as well as Ross Township in Butler County, Ohio.  It was a uranium processing facility located near the rural town of New Baltimore, about 20 miles (32 km) northwest of Cincinnati, which fabricated uranium fuel cores for the U.S. nuclear weapons production complex from 1951 to 1989.  During that time, the plant produced 170,000 metric tons uranium (MTU) of metal products and 35,000 MTU of intermediate compounds, such as uranium trioxide and uranium tetrafluoride. 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. The Kin-Buc Landfill is a 220 acre Superfund site located in Edison, New Jersey where 70 e6USgal of liquid toxic waste and 1 million tons of solid waste were dumped.  It was active from the late 1940s to 1976.  Cleanup operations have been underway to address environmental issues with contamination from 1980s through to 2000s.  This site was one of the largest superfund sites in New Jersey having taken in around 90 e6USgal .  The site is heavily contaminated with PCBs, which leaked into Edmonds Creek, a tributary of Raritan River. The Del Amo Superfund Site is a U.S. EPA Region 9 Superfund Site.  It is one of 94 Superfund Sites in California as of November 29, 2010. Douthat is a ghost town in Ottawa County, Oklahoma, United States.  Douthat is 2 mi south of Picher.  Douthat once had a post office, which opened on March 17, 1917.  The community was named after Zahn A. Douthat, the owner of the townsite.  Douthat is now abandoned and part of the Tar Creek Superfund site. 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.
