Although existing laws - Law on maintaining cleanliness and order in communities, or Act on Waste require owners and managers of land with the duty of the purity of his dealings are constantly emerging "wild dumps" garbage continues. Every year, new place to deposit all kinds of illegal waste. It is especially evident on the outskirts of town, adjacent to housing estates, near the little busy roads, on the edge of forests or in zadrzewieniach midfield. As you can guess the growing number of "wild dumps" is not without negative impact on the environment, particularly the soil environment. Each, newly created or existing for years, "wild dumps" garbage is a potential source of many different pollutants. The biggest threat will normally randomly selected places where garbage is not in any way secured. "Wild dumps" is not separated from the substrate layer geometry taken, nor do they have a separate seal waterproofing or protection zone. As a result, illegal dumping rubbish are a threat because: • the intrusion of toxic substances (including rain water) derived from the deposited waste into the soil. Seepage of leachate from the waste pollutes groundwater shallow deposits. This can cause contamination of drinking water in locations often far removed from the wild dumps. • Increase in soil various admixtures of anthropogenic origin (rubble and ceramics, slag, glass, plastics, metals, textiles wastes and others).

• Epidemiological Risks due to the possibility of the occurrence and development of the waste of many pathogenic bacteria, fungi and other pathogens (such as enterohaemorrhagic Escherichia, Proteus bacillus of the type: Salmonella, Shigella and S. enterica Yersenica). • The existence of problematic waste or hazardous (including remnants of electrolytes, paints, varnishes, batteries, expired medicines, insecticides), which are high risk, because the contaminate soil with heavy metals. The toxicity of heavy metals is manifested already in small concentrations. Can cause side effects to the proper functioning of living organisms (mutagenic, teratogenic or carcinogenic), preventing them from functioning properly. The main source of heavy metals in landfills are usually wild: hazardous waste, ash from individual heating systems, but also the organic fraction, which shows considerable capacity to their accumulation. Within the "wild dumps" are recorded elevated concentrations of copper, nickel, zinc, chromium, and even mercury.

• Rot of organic substances which are a source of unpleasant odors and cause air pollution (such as hydrogen sulfide and methane). • creating favorable conditions for development of flies, mosquitoes and rats, spread and disease. In addition, waste is eaten by animals may lead to their death, and shards of glass, metals may hurt animals, strings lead to tangling of legs, especially birds.
