Beach on the IJmeer in the Diemerpark, with a view of IJburg
Diemerpark is the largest urban park in Amsterdam with an area of around 90 hectares, making it about twice as large as the famous Vondelpark in Amsterdam-Centrum. Diemerpark, located between IJburg and the Amsterdam-Rhine Canal, was opened in 2004 and offers numerous recreational opportunities for visitors.
In the 12th century, the "Diemerzeedijk" (English: Diemerseadike) was built to protect the surrounding land against the floods of the Zuiderzee. However, the dikes bursted often. In 1932, the Afsluitdijk transformed the Zuiderzee into an inland lake without the devastating floods of the past. The area around the lake thus became a natural area with rich vegetation and many animal species.[1]
In the 1960s and 1970s, the area of today's nature and urban park was used as a landfill for household and chemical waste. This made the Diemerzeedijk one of the most polluted places in the Netherlands. Until 1973, chemical waste was burned in a part of the area. This caused the area to become very polluted.[2] Ten years later the dump was permanently closed. Soil remediation took place from 1998 to 2001. In 2004, the park was opened to visitors.[3] The chemical waste was dumped illegally for years. The municipality of Amsterdam was able to avoid legal prosecution in a settlement procedure (Dutch: "schikking") by paying 100,000 euros to the Dutch state.[4]
However, after the landfill was closed, a rugged nature reserve with a great biodiversity developed. Research showed that the pollution did not pose a direct danger to humans and animals, but because of the construction of IJburg, plans were made to clean up the area. Because of the extent of the pollution, the area was "wrapped" underground by sheet piles and covered with a waterproof top layer consisting of bentonite clay and foil. The park was built on top of that. This makes the park a kind of roof garden on the former landfill. As a result, visitors are not allowed to dig holes, and it is not possible to leave deep-rooted trees of more than 5 meters high there.[5] The groundwater is pumped away and purified. A story can be read on the manhole covers.[citation needed]
At the entrances to the park, visitors are made aware that there are some restrictions on using the nature park: neither humans nor dogs are allowed to dig on the site, the installation of poles or tent pegs is prohibited and dogs must be kept on a leash.[6] According to the municipality of Amsterdam, the groundwater is not contaminated and therefore harmless to trees and plants. The southeastern part of the park is largely inaccessible to visitors as it consists of swamp. There are now a large number of animals in the natural area, around 200 species of birds, grass snakes, shrews, nightingales, bluethroats, kingfishers and others.[7] In addition, around 200 plant species have been counted and some mammals have returned to the nature park, including deer, bats and stoats. Reptiles such as the grass snake are harmless to visitors.[citation needed]
Events
The sixth theatre festival took place on September 6, 2010, with street, music, puppet theatre and dance performances. On the west-side is a sports venue with 3 football pitches and 3 hockey fields. There are also hiking and cycling trails, a small beach and open-air theatre. The last festival took place on September 9, 2012.[8]
Access
The park is connected via bridges to the Rieteilanden of IJburg. It is also accessible via the Nescio Bridge over the Amsterdam-Rhine Canal or via the Diemerzeedijk.

A landfill is a site for the disposal of waste materials. It is the oldest and most common form of waste disposal, although the systematic burial of waste with daily, intermediate and final covers only began in the 1940s. In the past, waste was simply left in piles or thrown into pits.
Industrial waste is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process such as that of factories, mills, and mining operations. Types of industrial waste include dirt and gravel, masonry and concrete, scrap metal, oil, solvents, chemicals, scrap lumber, even vegetable matter from restaurants. Industrial waste may be solid, semi-solid or liquid in form. It may be hazardous waste or non-hazardous waste. Industrial waste may pollute the nearby soil or adjacent water bodies, and can contaminate groundwater, lakes, streams, rivers or coastal waters. Industrial waste is often mixed into municipal waste, making accurate assessments difficult. An estimate for the US goes as high as 7.6 billion tons of industrial waste produced annually, as of 2017. Most countries have enacted legislation to deal with the problem of industrial waste, but strictness and compliance regimes vary. Enforcement is always an issue.
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.
Environmental remediation is the cleanup of hazardous substances dealing with the removal, treatment and containment of pollution or contaminants from environmental media such as soil, groundwater, sediment. Remediation may be required by regulations before development of land revitalization projects. Developers who agree to voluntary cleanup may be offered incentives under state or municipal programs like New York State's Brownfield Cleanup Program. If remediation is done by removal the waste materials are simply transported off-site for disposal at another location. The waste material can also be contained by physical barriers like slurry walls. The use of slurry walls is well-established in the construction industry. The application of (low) pressure grouting, used to mitigate soil liquefaction risks in San Francisco and other earthquake zones, has achieved mixed results in field tests to create barriers, and site-specific results depend upon many variable conditions that can greatly impact outcomes.
Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations like milk and egg production. It may be performed in plants using mechanized treatment units similar to those used for industrial wastewater. Where land is available for ponds, settling basins and facultative lagoons may have lower operational costs for seasonal use conditions from breeding or harvest cycles. Animal slurries are usually treated by containment in anaerobic lagoons before disposal by spray or trickle application to grassland. Constructed wetlands are sometimes used to facilitate treatment of animal wastes.
A leachate is any liquid that, in the course of passing through matter, extracts soluble or suspended solids, or any other component of the material through which it has passed.
Munisport Landfill is a closed landfill located in North Miami, Florida adjacent to a low-income community, a regional campus of Florida International University, Oleta River State Park, and estuarine Biscayne Bay.
Landfills in the United Kingdom were historically the most commonly used option for waste disposal. Up until the 1980s, policies of successive governments had endorsed the "dilute and disperse" approach. Britain has since adopted the appropriate European legislation and landfill sites are generally operated as full containment facilities. However, many dilute and disperse sites remain throughout Britain.
IJburg is a residential neighbourhood under construction in Amsterdam, Netherlands. It is situated in the IJmeer and is being built on artificial islands which have been raised from the lake. The Haveneiland, Rieteilanden, Steigereiland and Centrumeiland are already inhabited as of 2004. It is part of the municipality Amsterdam-Oost and also contains the Diemerpark, one of the city's largest parks.
Groundwater remediation is the process that is used to treat polluted groundwater by removing the pollutants or converting them into harmless products. Groundwater is water present below the ground surface that saturates the pore space in the subsurface. Globally, between 25 per cent and 40 per cent of the world's drinking water is drawn from boreholes and dug wells. Groundwater is also used by farmers to irrigate crops and by industries to produce everyday goods. Most groundwater is clean, but groundwater can become polluted, or contaminated as a result of human activities or as a result of natural conditions.
Municipal solid waste (MSW) – more commonly known as trash or garbage – consists of everyday items people use and then throw away, such as product packaging, grass clippings, furniture, clothing, bottles, food scraps and papers. In 2018, Americans generated about 265.3 million tonnes of waste. In the United States, landfills are regulated by the Environmental Protection Agency (EPA) and the states' environmental agencies. Municipal solid waste landfills (MSWLF) are required to be designed to protect the environment from contaminants that may be present in the solid waste stream.
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.
Thurrock Thameside Nature Park is an Essex Wildlife Trust nature reserve located on top of the former Mucking Marshes Landfill in Thurrock, England which will eventually cover 845 acres (342 ha). It is next to the River Thames and provides good bird and ship watching. The Cory Environmental Trust Visitor Centre is located at the preserve and provides a rooftop viewing platform.
The Nescio Bridge is a cycle and footbridge in the Netherlands. This curved, steel suspension bridge, located in Amsterdam, is the country's first suspension bridge that carries only a cycle track and footway, and at almost 800 metres length it is also one of the country's longest cycle and footbridges. Additionally, it is the longest single cable suspension bridge in the Netherlands.
The Central Landfill is a 154-acre (62 ha) waste disposal site in Johnston, Rhode Island. It is the state's only landfill and receives more than 90% of the state's solid waste. It has been on the Environmental Protection Agency's Superfund National Priorities List since 1986. The site is owned and operated by the Rhode Island Resource Recovery Corporation (RIRRC).
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.
Groundwater pollution, also referred to as groundwater contamination, is not as easily classified as surface water pollution. Groundwater aquifers are susceptible to contamination from sources that may not directly affect surface water bodies.
The Glen Lily Landfill is an inactive municipal solid waste landfill located in unincorporated Warren County, Kentucky northwest of the city of Bowling Green. The landfill accepted residential and industrial waste from 1975 to 1979; after being idled, carcinogenic pollutants were found to be leaching into nearby groundwater. Remediation of the facility was administered as a Superfund site by the state of Kentucky.
The Beatrixpark is a park in the Amsterdam-Zuid borough and is located in the "Prinses Irenebuurt" residential area. The park was named after the former Dutch Queen Beatrix. In 1972, part of the park, together with the Amstelpark, was the site of the Floriade garden and agricultural exhibition.
