===Environmental remediation===
[[Environmental remediation]] is the process through which contaminants or pollutants in soil, water and other media are removed to improve environmental quality. The main focus is the reduction of hazardous substances within the environment. Some of the areas involved in environmental remediation include; [[soil contamination]], [[hazardous waste]], groundwater contamination, oil, gas and chemical spills. There are three most common types of environmental remediation. These include soil, water, and sediment remediation. <ref name="ancoenv">{{Cite web |date=2022-09-20 |title=What Are the 3 Main Types of Site Remediation? |url=https://www.ancoenv.net/what-are-the-3-main-types-of-site-remediation |access-date=2024-04-25 |website=www.ancoenv.net |language=en}}</ref>           

Soil remediation consists of removing contaminants in soil, as these pose great risks to humans and the ecosystem. Some examples of this are heavy metals, pesticides, and radioactive materials. Depending on the contaminant the remedial processes can be physical, chemical, thermal, or biological.           

Water remediation is one of the most important considering water is an essential natural resource. Depending on the source of water there will be different contaminants. Surface water contamination mainly consists of agricultural, animal, and industrial waste, as well as acid mine drainage. <ref>{{Cite web |date=2021-02-25 |title=The main three types of environmental remediation and reclamation - Anderson Engineering |url=https://www.andersoneng.com/the-main-three-types-of-environmental-remediation-and-reclamation/ |access-date=2024-04-25 |language=en-US}}</ref> There has been a rise in the need for water remediation due to the increased discharge of industrial waste, leading to a demand for sustainable water solutions. The market for water remediation is expected to consistently increase to $19.6 billion by 2030. <ref>{{Cite press release |last=LLC |first=Rationalstat |date=2023-11-27 |title=Industrial Wastewater Treatment Market to Reach US$ 19.6 Billion by 2030, Driven by Stringent Environmental Regulations and Growing Demand for Sustainable Water Management Solutions {{!}} According to RationalStat |url=https://www.globenewswire.com/en/news-release/2023/11/27/2785883/0/en/Industrial-Wastewater-Treatment-Market-to-Reach-US-19-6-Billion-by-2030-Driven-by-Stringent-Environmental-Regulations-and-Growing-Demand-for-Sustainable-Water-Management-Solutions-.html |access-date=2024-04-25 |website=GlobeNewswire News Room |language=en}}</ref>          

Sediment remediation consists of removing contaminated sediments. Is it almost similar to soil remediation except it is often more sophisticated as it involves additional contaminants. To reduce the contaminants it is likely to use physical, chemical, and biological processes that help with source control, but if these processes are executed correctly, there's a risk of contamination resurfacing. <ref name="ancoenv" /><ref>{{Cite web |date=2018-02-27 |title=Sediment Remediation • EnvGuide |url=https://us.envguide.com/sediment-remediation-2/ |access-date=2024-04-25 |website=EnvGuide |language=en-US |last1=Eg |first1=Contributor01 }}</ref>
