Environmental protection

Storage areas of pesticides with past their sell-by date (waste burials) are one of the most dangerous objects threatening the natural environment in Poland. In the turn of 1970s and 80s, unnecessary chemical reagents or other dangerous wastes were deposited in those burial grounds. Such grounds pose a threat to the system of underground waters and grounds, as well as to the atmospheric air to a lower degree. Most of such objects were closed down in 1975- 85, and the protection and shaping natural environment act practically made it impossible to localise such objects. Thus, finding and rendering harmless such underground storage areas of different chemical wastes constitutes one of the most difficult tasks in the environmental protection from many years.

Old, covered with a layer of embankment, illegal storage areas of communal, hospital and dangerous waste are also a serous problem. Most of all, they are the source contamination of underground water and ground itself. They may also pose a potential geotechnical threat, is such ground are allotted for housing.

By means of the GPR, it is possible to determine exact locations of waste burials and waste storage areas, as well as their depth. Furthermore, the usage of GPR makes it possible to determine the actual geometry of waste storage areas and obtain their three-dimensional model after some data processing.

Frequent cause of ground contamination is the leakage from tanks and pipelines due to installation unsealing. Cases of pipeline damages caused by an unauthorised access were reported. The contamination of grounds, underground waters, rivers and water tanks is the result of oil leakage..

The basic usage of GPR in ground contamination by oil-derivatives survey provides us with the possibility only to determine the place of contamination. However, thorough data analysis permits even to determine the density of substance contaminating the ground. Besides, it is unimportant whether the contaminating area is covered with sand or it is uncovered. The GPR will detect the contamination even under a thick layer of stones or concrete.
