) 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.

Many less-developed countries that are becoming industrialized do not yet have the resources or technology to dispose their wastes with minimal impacts on the environment. Both untreated and partially treated wastewater are commonly fed back into a near lying body of water. Metals, chemicals and sewage released into bodies of water directly affect marine ecosystems and the health of those who depend on the waters as food or drinking water sources. Toxins from the wastewater can kill off marine life or cause varying degrees of illness to those who consume these marine animals, depending on the contaminant.

Water pollution

One of the most devastating effects of industrial waste is water pollution. For many industrial processes, water is used which comes in contact with harmful chemicals. These chemicals may include organic compounds (such as solvents), metals, nutrients or radioactive material. If the wastewater is discharged without treatment, groundwater and surface water bodies—lakes, streams, rivers and coastal waters—can become polluted, with serious impacts on human health and the environment. Drinking water sources and irrigation water used for farming may be affected. The pollutants may degrade or destroy habitat for animals and plants. In coastal areas, fish and other aquatic life can be contaminated by untreated waste; beaches and other recreational areas can be damaged or closed.

(MSW) management and industrial waste management are organized by the Royal Thai Government, which is organized as central (national) government, regional government, and local government. Each government is responsible for different tasks. The central government is responsible for stimulating regulation, policies, and standards. The regional governments are responsible for coordinating the central and local governments. The local governments are responsible for waste management in their governed area. However, the local governments do not dispose of the waste by themselves but instead hire private companies that have been granted the right from the Pollution Control Department (PCD) in Thailand. The main companies are Bangpoo Industrial Waste Management Center, General Environmental Conservation Public Company Limited (GENCO), SGS Thailand, Waste Management Siam LTD (WMS), and Better World Green Public Company Limited (BWG). These companies are responsible for the waste they have received from their customers before releasing it to the environment, burying it.

—corrective action is when treatment, storage, and disposal facilities (TSDFs) must oblige with inquiring hazardous releases into ground and surface water, soil, and air, and clearing it up. Under the HSWA, the EPA can necessitate corrective action at permitted and non-permitted TSDFs. Furthermore, the EPA uses Superfund to find sites of contamination, identify the parties responsible, and in the occurrences where said parties are not known or able to, the program funds cleanups. Superfund also works on figuring out and applying final remedies for cleanups. The Superfund process is to: 1) collect necessary information (known as the Remedial Investigation (RI) phase); 2) assess alternatives to deal with any potential risks to the environmental and human health (known as the

Some sites are so contaminated because of past waste disposals that it takes decades to clean them up, or bring the contamination down to acceptable levels, thus requiring long-term management over those sites. Hence, sometimes figuring out a final remedy is not possible, and so, the EPA has developed the

programs. State compliance is monitored by EPA inspections. In the case that waste management guideline standards are not met, action against the site will be taken. Compliance errors may be corrected by enforced cleanup directly by the site responsible for the waste or by a third party hired by that site. Prior to the enactment of the Clean Water Act (1972) and RCRA, open dumping or releasing wastewater into nearby bodies of water were common waste disposal methods. The negative effects on human health and environmental health led to the need for such regulations. The RCRA framework provides specified subsections defining nonhazardous and hazardous waste materials and how each should be properly managed and disposed of. Guidelines for the disposal of nonhazardous solid waste includes the banning of open dumping. Hazardous waste is monitored in a "

" fashion; each step in the process of waste generation, transport and disposal is tracked. The EPA now manages 2.96 million tons of solid, hazardous and industrial waste. Since establishment, the RCRA program has undergone reforms as inefficiencies arise and as waste management processes evolve. The 1972 Clean Water Act is a broad legislative mandate to protect surface waters (rivers, lakes and coastal water bodies). A 1948 law had authorized research and development of voluntary water standards, and had provided limited financing for state and local government efforts. The 1972 law prohibited, for the first time, uncontrolled discharges of industrial waste, as well as municipal sewage, into waters of the United States. EPA was required to develop national standards for industrial facilities and standards for municipal sewage treatment plants. States were required to develop water quality standards for individual water bodies. Enforcement is mainly delegated to state agencies. Major amendments to the law were passed in 1977 and 1987.
