Hazardous wastes improper disposal

As defined under the Resource Conservation and Recovery Act (RCRA), any solid or combination of solid wastes that, because of its physical, chemical, or infectious characteristics, may pose a hazard when improperly disposed of. Possesses at least one of four characteristics (ignitability, corrosivity, reactivity, or toxicity), or appears on special Environmental Protection Agency (EPA) lists. See also Resource Conservation and Recovery Act (RCRA). 

CERCLA, or Superfund, was enacted in 1980, and amended in 1986, for the basic purpose of providing funding and enforcement authority to clean up any site where there is a past unremedied release of a hazardous substance or hazardous substance spill. Such sites are typically characterized as areas where hazardous waste or materials have been disposed of improperly, with litde if any responsible action being taken to mitigate the situation. Standards for financial responsibility were promulgated by the SARA of 1986 which further amended Section 9003 of RCRA and mandated that the EPA establish financial responsibility requirements for UST owners and operators to guarantee cost recovery for corrective action and third-party liability caused by accidental releases of USTs containing petroleum products. 

A chemical waste is any solid, liquid, or gaseous waste material that if improperly managed or disposed of, may pose substantial hazards to human health and the environment (Table 1.2). At any stage of the management process, a chemical waste may be designated by law as a hazardous waste (Chapter 12). Improper disposal of such waste streams in the past has created a need for very expensive cleanup operations (Tedder and Pohland, 1993). Correct handling of such... 

Release routes of 3,3 -dichlorobenzidine to the environment appear to be waste waters, sludges, and solid wastes where emissions are not properly controlled during the use of 3,3 -dichlorobenzidine or during its chemical transformation to pigments. The compound has been found in water and soil at hazardous waste sites, a result of the improper land disposal of solid wastes. 

As a generator, an industrial plant always retains responsibility for hazardous waste. If the plant s waste is dumped or disposed of improperly, the plant manager and the owner wiU be held responsible. It is therefore important that the plant manager or the owner knows where the plant s waste is going and whether or not it is handled properly and safely [73]. 

The RCRA has also outlined a set of systematic rules governing the transport of hazardous waste. A detailed manifest system was established, where a manifest is to be prepared for each shipment of hazardous waste. The manifest includes information on the generator, the nature of the waste, and the quantity. Each transporter of the waste is required to sign and verify the manifest and keep a copy. When the waste reaches its destination, a copy signed by all parties is returned to the origination point to verify arrival of the waste. This system ensures that no waste is lost or disposed of improperly. 

One of the most critical areas for the prevention of toxicity caused by environmental contamination is that of disposal of hazardous wastes. It is now apparent that past practices in many industrialized countries have created large numbers of waste sites in which the waste is often unidentified, improperly stored, and leaching into the environment. The task of rectifying these past errors is an enormous one just now being addressed. 

Exposure to toxicants from terrestrial sources is very common because of the intimate association between animals and plants that live on the land with soil. Modem agricultural practices call for the application of large quantities of herbicides and other pesticides to plants and soil residues of these substances may readily enter living organisms. Soil is the repository of a variety of air pollutants, especially airborne particles that settle onto soil. Improper disposal of industrial wastes and toxic substances washed from or blown off of hazardous waste sites has contributed to exposure of soil. 

You may dispose of hazardous waste as outlined below. It is the responsibility of the generator to ensure hazardous waste does not end up in ground water, soil or the atmosphere through improper disposal. 

Significant adverse effects on environmental quality, ecosystem integrity, and human health have often been associated with improper disposal of hazardous materials. A study ascertained the levels of eight potentially toxic elements in various fish species that were collected from a local hazardous-waste-contaminated wetland and estimated the potential health risk associated with consuming such fish [24]. A total of 53 fish samples representing 12 different species were examined. The respective mean concentrations (in ng g-1) of As, Cd, Cr, Cu, Fe, Pb, Hg, and Ni found in edible tissues were as follows 72.5 + 103.1, 55.4 + 34.6,... 

In recent years, improper disposal of various waste materials has posed serious threats to surface and groundwater supplies and developed into a global scale soil and water pollution problem [1], Heavy metals account for much of the contamination found at hazardous waste sites in the United States, and have been detected in the soil and groundwater at approximately 65% of the U.S. Environmental Protection Agency Superfund sites [2], Dramatic increases in land application of agricultural and municipal biosolids have accentuated the problem. In spite of their beneficial contributions as nutrient sources and soil conditioners, these amendments, if not monitored, pose a considerable environmental risk because of their high heavy-metal concentrations [3],... 

As a result of these improper disposal practices, sites contaminated with hazardous wastes came to public attention throughout the 1970s and 1980s. The effects of improper hazardous waste disposal may persist for decades or even centuries when the contaminants have low degradation rates and migrate slowly through the subsurface. 

These provisions provide a tremendous impetus to hazardous waste generators to dispose of their waste on site under carefiilly controlled conditions. This concept of liability also burdens the generator with the threat of future costs as a result of someone else s improper actions. These values follow directly from our system of government, which was created to assure that individual citizens do not suffer loss of property and freedoms (health) by the actions of others. The need for a careful choice of a contractor to carry out waste management and disposal responsibilities is also highlighted by these provisions.

Thus, for example, the majority of PCBs in air result from volatilization of PCBs from soil and water. Some PCBs may be released to the atmosphere from uncontrolled landfills and hazardous waste sites incineration of PCB-containing wastes leakage from older electrical equipment in use and improper disposal or spills (Blumbach and Nethe 1996 Boers et al. 1994 Bremle and Larsson 1998 Eisenreich et al. 1992 Hansen and O Keefe 1996 Hansen et al. 1997 Hennanson and Hites 1989 Larsson 1985 Lewis et al. 1985 Morselli et al. 1985, 1989 Murphy et al. 1985 Oehme et al. 1987 ... 

The issue of pesticide waste disposal has been recognized as a national problem for years, yet today remains as one of the foremost problems confronting most pesticide users. In any Extension meeting that addresses pesticide safety issues, the most frequently discussed topic is that of pesticide waste disposal. The undisputable fact is that adequate hazardous waste disposal facilities do not presently exist for small volume pesticide users. Improper, albeit not necessarily irresponsible, handling of pesticide wastes and containers often results in unacceptable levels of environmental contamination and excessive exposure to the applicators themselves. 

Criminal liability for improper disposal of hazardous waste. Responsibilities of waste generators, companies, and individuals. 

CERCLA s purpose is to authorize the federal government to respond swiftly to hazardous substance emergencies and to protect public health and the environment by cleaning up the nation s worst hazardous waste sites (Reisch and Bearden, 1997). The law seeks to make those responsible for the improper disposal of hazardous waste bear the costs and accept responsibility for their actions with a retroactive liability regime, and established the Hazardous Substance Superfund Trust Fund to finance response actions where a liable party cannot be found or is incapable of paying cleanup costs. The Superfund program is the principal federal effort to clean up inactive hazardous waste sites. 

RDX particles can enter the air when it is disposed of by burning. RDX can enter the water from disposal of waste water from Army ammunition plants, and can enter water or soil from spills or leaks from improper disposal at these plants or at hazardous waste sites. RDX dissolves very slowly and to a limited extent in water, and it also evaporates very slowly from water. It does not cling to soil very strongly and can get into the groundwater from soil. RDX can be broken down in air and water in a few hours, but it breaks down more slowly in soil. RDX does not build up in fish or in people. See Chapters 4 and 5 for more information on RDX in the environment. 

Under special EPA requirements, hazardous waste shippers must mark each shipping container of 110 gallons or less with this warning HAZARDOUS WASTE—Federal Law Prohibits Improper Disposal. If found, contact the nearest police or public safety authority or the U.S. Environmental Protection...
