What are illegal dumps and tire piles?
An illegal dump is a site where waste is disposed of without a permit. Illegal dumping is also called open dumping, fly dumping, or midnight dumping when materials are dumped in open areas, from vehicles along roads, or late at night. A legal, sanitary landfill is a land disposal site for non-hazardous household solid waste, where the waste is spread in compacted layers. Human exposure to landfill gas can cause respiratory problems, central nervous system damage, and cancer.
Illegally dumped materials can include construction waste, automobiles, auto parts, scrap tires, appliances, furniture, and medical waste. Scrap tires and bulky items may be illegally dumped because they are banned from landfills and their proper disposal may be expensive. An illegal dump can also contain any toxic chemicals or hazardous materials that someone chooses to discard.
Illegal dumps can cause not only the same human health risks as landfills, but also other health threats. Rodents, insects, and other disease-carrying pests are attracted to dump sites. Polluted water runoff from dump sites can contaminate wells and other sources of drinking water. Disease-carrying mosquitoes can breed in the rain water that collects inside discarded tires. Tire fires can burn for a long time, polluting the air, soil, and water with gases, heavy metals, and oil.
Smoke from tire fires can include benzene, polycyclic aromatic hydrocarbons, and styrene. Benzene is listed as a human carcinogen in the Fourteenth Report on Carcinogens published by the National Toxicology Program; styrene and some polycyclic aromatic hydrocarbons are listed as "reasonably anticipated to be human carcinogens."
