Ogólne informacje dotyczące występowania zanieczyszczeń środowiska gruntowo-wodnego na terenach poprzemysłowych. Omówienie procedur formalnych, wyboru lokalizacji badań i ich zakresu oraz wymagań dotyczących zapewnienia jakości wykonania. Schematy i metody poboru próbek oraz opracowanie wyników badań oraz podejmowanie decyzji dotyczących działań rekultywacyjnych i zagospodarowania porekultywacyjnego.

General information on the occurrence of soil and water contamination in industrial areas. Discussing formal procedures, choosing the location and research of soil and water tests and requirements concerning workmanship. Schemes and methods of sampling as well as elaborating research results and making decisions regarding remediation and post-treatment activities.

The article discusses purification of groundwater contaminated with chlorinated solvents including tetrachlorethane (PCE) and trichloroethene (TCE), using reactive barriers and in situ injection. For the dehalogenation of complex chlorinated hydrocarbons, a reagent consisting of zero-value controlled iron and nutrient-stimulating bio-degradable substances was used in the remediation works. The effectiveness of remediation ofsoil and water contaminated with TCE and PCE depends on the degree ofunderstanding of the processes that pollutants undergo. The combination of three methods made it possible to reduce pollution in groundwater by 80%. The Regulation on the Register of Historic Land Pollution, introduced in September 2016, paves the way for restoring contaminated land to its initial quality with the remediation processes, but does not answer the question of how to assess the quality of water in the context of the proposed remediation work.

The article presents an analysis of selected methods of remediation of land and groundwater, performed on the site in the ground (ie. in-situ) or on the treated plot, as alternatives to soil excavation treating, of ten many kilometers outside the investments (ex-situ). The choice of the appropriate method depends on the geological and environmental conditions, the type and the volume of pollutant concentrations and the planned development of the land. Remediation methods are designed to reduce the negative impact of hazardous substances on the environment and on human health, who may be exposed to the pollution.
