Toluene, also known as toluol, is a substituted aromatic hydrocarbon with the chemical formula C6H5CH3, often abbreviated as PhCH3, where Ph stands for phenyl group. It is a colorless, water-insoluble liquid with the odor associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a methyl group (CH3) attached to a phenyl group by a single bond. As such, its systematic IUPAC name is methylbenzene. Toluene is predominantly used as an industrial feedstock and a solvent.
Toxic waste is any unwanted material in all forms that can cause harm. Mostly generated by industry, consumer products like televisions, computers, and phones contain toxic chemicals that can pollute the air and contaminate soil and water. Disposing of such waste is a major public health issue.
Trichloroethylene (TCE) is a halocarbon with the formula C2HCl3, commonly used as an industrial degreasing solvent. It is a clear, colourless, non-flammable, volatile liquid with a chloroform-like pleasant mild smell and sweet taste. Its IUPAC name is trichloroethene. Trichloroethylene has been sold under a variety of trade names. Industrial abbreviations include TCE, trichlor, Trike, Tricky and tri. Under the trade names Trimar and Trilene, it was used as a volatile anesthetic and as an inhaled obstetrical analgesic. It should not be confused with the similar 1,1,1-trichloroethane, which is commonly known as chlorothene.
The Toms River is a 41.7-mile-long (67.1 km) freshwater river and estuary in Ocean County, New Jersey in the United States.
Diazinon, a colorless to dark brown liquid, is a thiophosphoric acid ester developed in 1952 by Ciba-Geigy, a Swiss chemical company. It is a nonsystemic organophosphate insecticide formerly used to control cockroaches, silverfish, ants, and fleas in residential, non-food buildings. Diazinon was heavily used during the 1970s and early 1980s for general-purpose gardening use and indoor pest control. A bait form was used to control scavenger wasps in the western U.S. Diazinon is used in flea collars for domestic pets in Australia and New Zealand. Diazinon is a major component in the "Golden Fleece" brand sheep dip. Residential uses of diazinon were outlawed in the U.S. in 2004 because of human health risks but it is still approved for agricultural uses. An emergency antidote is atropine.
Ethylbenzene is an organic compound with the formula C6H5CH2CH3. It is a highly flammable, colorless liquid with an odor similar to that of gasoline. This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene, the precursor to polystyrene, a common plastic material. In 2012, more than 99% of ethylbenzene produced was consumed in the production of styrene.
The Laurel Park, Inc. site, also known as Hunters Mountain Dump, or Murtha's Dump to locals, is a capped landfill that occupies approximately 20 acres (81,000 m2) of a 35-acre (140,000 m2) parcel of land in Naugatuck, Connecticut. The landfill has been in existence since the late 1940s, and several industries disposed of solvents, oils, hydrocarbons, chemical and liquid sludge, chemical solids, tires, and rubber products there. The facility continued to operate as a municipal landfill until 1987. It was owned and operated by Terrence and Howard Murtha.
The Lipari Landill is an inactive landfill on a 6-acre (2.4 ha) former gravel pit in Mantua Township, New Jersey. It was used from 1958 to 1971 as a dump site for household and industrial wastes. Toxic organic compounds and heavy metals dumped at the site have percolated into the ground water and leached into lakes and streams in the surrounding area. The site has been identified as the worst toxic dump in the United States and was ranked at the top of the United States Environmental Protection Agency's Superfund eligibility list.
The Omega Chemical Corporation was a refrigerant and solvent recycling company that operated from 1976 to 1991 in Whittier, California. Due to improper waste handling and removal, the soil and groundwater beneath the property became contaminated and the area is now referred to as the Omega Chemical Superfund Site. Cleanup of the site began in 1995 with the removal of hazardous waste receptacles and a multimillion-dollar soil vaporization detoxifying system.
The former Operating Industries Inc. Landfill is a Superfund site located in Monterey Park, California at 900 N Potrero Grande Drive. From 1948 to 1984, the landfill accepted 30 million tons of solid municipal waste and 300 million US gallons (1,100,000 m3) of liquid chemicals. Accumulating over time, the chemical waste polluted the air, leached into groundwater, and posed a fire hazard, spurring severely critical public health complaints. Recognizing OII Landfill's heavy pollution, EPA placed the financial responsibility of the dump's clean-up on the main waste-contributing companies, winning hundreds of millions of dollars in settlements for the protection of human health and the environment.
The Waste Disposal Inc. Superfund site is an oil-related contaminated site in the highly industrialized city of Santa Fe Springs in Los Angeles County, California. It is approximately 38 acres (15 ha), with St Paul's high school immediately adjacent to the northeast corner of the site. Approximately 15,000 residents of Santa Fe Springs obtain drinking water from wells within three miles (4.8 km) of the site.
The Rockaway Borough Well Field is a Superfund site that came into place in 1981 after the soil was suspected of being contaminated with toxic chemicals. The site is located in Rockaway, Morris County, New Jersey. It was first found to be an official Superfund site after it was discovered that tetrachloroethene (PCE) and trichloroethylene (TCE) were contaminating the soil. Studies suspected that the chemicals were coming from the area of two companies in the town of Rockaway. In 1985, the residents of Rockaway were advised not to drink the tap water and the National Guard had to come and supply water supplies for the community. The town soon installed a water filter system in order to try to reduce the amount of pollution in the water. After finding that the system was not effective, the NJDEP came to the scene to investigate the soil. NJDEP found that the soil tested positive with chemicals and from there the EPA were contacted. The EPA found chemicals in different areas of the borough and found that the soil was contaminated and began to install a groundwater treatment system that functioned to purify the ground of chemicals. The system was soon pumping up to 900,000 gallons of water from the boroughs wells. Today, the pump is still functioning and has since reduced the amount of chemicals and the chance of pollution in the water to appear again. The final project to completely purify the water is still in production.
The Combe Fill South Landfill is located on the border of Chester and Washington townships, both of which are in Morris County, in the state of New Jersey. The Landfill was put on the National Priority List by the EPA in September 1983 due to the site being tested for potentially dangerous chemicals, such as benzene, methylene chloride, and chloroform. Despite attempts to clean up, the site has remained an active Superfund as of September 25, 2017.
Emmell's Septic Landfill (ESL) is located at 128 Zurich Ave, 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 Diamond Head Oil Refinery is a former oil reprocessing facility located in Kearny, New Jersey, United States, that was designated as a Superfund site by the Environmental Protection Agency (EPA). It opened up in 1946, but then stopped production in 1979 and has been inactive since then. The refinery was shut down in 1980 and the EPA designated it as a Superfund site in 1991 due to the discovery of toxic chemicals in the soil and the surface water. This created a dangerous work environment for the workers at the facility. The EPA proposed a clean up plan for the site, but it has yet to take effect. So far, the Diamond Head site is still in the process of being cleaned up. Although cleanup plans were discussed and finalized, the future of the Diamond Head Oil Refinery and its cleanup state is unknown.
Bog Creek Farm, located in Howell Township, New Jersey, is a designated Environmental Protection Agency (EPA) Superfund site. Lying on 12 acres of land, Bog Creek Farm is home to several hazardous and life-threatening contamination beginning in 1973 and continuing for a year. Over a decade later, actions began to take place to clean and restore the contaminated soil and water. Bog Creek Farm is situated near several other farms that house horses, growing crops and flowers, and livestock. Less than a mile down the road lies Allaire State Park, a park used by golfers, hunters, and fisherman.
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 that is slightly above sea-level. The company, known as the Chemical Control Corporation, worked as a hazardous waste disposal plant from 1972 until its condemnation in 1979. Before the April 21, 1980 fire, it was reported that over 50,000 drums of chemicals, ranging from 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.
The Orange Valley Regional Groundwater Superfund site is a group of wells in Orange and West Orange, two municipalities in Essex County, New Jersey, United States. The groundwater in the public wells are contaminated with the hazardous chemicals of Trichloroethylene (TCE), Dichloroethene (DCE), Tetrachloroethylene (Perchloroethene), 1,1-Dichloroethene (1,1-DCE), and 1,2-Dichloroethene (1,2-DCE). These chemicals pose a huge risk to the towns nearby population, as the wells are a source of public drinking water. In March 2012, the site was added to the National Priorities List (NPL) of the United States Environmental Protection Agency (EPA) Superfund site list.
Price Landfill is a 26-acre site located in Pleasantville, Egg Harbor Township, Atlantic County, New Jersey. Price Landfill is also known as Price Sanitary Landfill, Prices Pit, Price Landfill No.1 and Price Chemical Dump. The United States Environmental Protection Agency (USEPA) added Price Landfill to the Superfund National Priorities List on September 20, 1983, because of the hazardous chemicals found on the site and in the groundwater. The site was originally owned by Mr. Charles Price and was used to mine sand and gravel, which was shut down in 1968. The site was then turned into a private landfill in 1969 and then a commercial solid waste landfill in 1971. At this point the landfill was used to dispose of liquid waste by companies, specifically Atlantic City Electric Company. The liquid waste consisted of industrial chemicals, oils and greases/sludges, septic tank and sewer wastes, which were disposed on the site for 8 years, ending altogether in 1976, but in the meantime, having contaminated the groundwater, soil, air, and nearby creeks, specifically Absecon Creek. Chemicals dumped on the site are believed to be 1,2-Dichloroethane, arsenic, benzene, chloroform, lead, and vinyl chloride, all of which contaminated the groundwater, soil, air, and nearby creeks. The USEPA originally got involved in 1982 by beginning to correct the damage. Currently the USEPA states that they are continuing to monitor and treat the groundwater and land, and that hazards to humans are controlled.
Ohio River Park is a Superfund Site located in Neville Island, Pennsylvania. Between the 1920s-1970s, the Site was used for municipal waste, pesticide manufacturing, coke sludge disposal, cement manufacturing disposal, and pesticide waste. In 1977, Neville Land Company donated the Site to Allegheny County who started developing the Site as a community park. In 1979, Allegheny County found various hazardous contaminants on the Site. On August 30, 1990, the Site was determined to be a Superfund Site due to VOCs, SVOCs, inorganics, and pesticides being present in the surface soil, subsurface soil, surface water, river sediment, and groundwater. Soil remediation began in February 1998 and ended in September 1999. Today, Ohio River Park has the Robert Morris University Island Sports Center and Coraopolis Bridge on top of it. Additionally, benzene continues to be monitored because it is still present in the Site's groundwater.
