The impacts of industrial wastewater contamination on the geotechnical properties of clayey soil have been studied in the research presented in this paper. The contaminant in question is industrial wastewater released from Thi-Qar oil refinery as a by-product of production, and the soil samples obtained from Thi-Qar oil refinery plant in Al-Nassyriah (a city located in the south of Iraq). The geotechnical properties of contaminated soil samples were compared with those of intact soil to measure the effects of such a contaminant. The soil samples were obtained from three locations in the study area; representing the highly contaminated area, the slightly contaminated area, and the intact area used as a reference for comparison of test results. The results of the tests showed that the contaminant causes an increase of natural moisture content, field unit weight, Atterberg’s limits, and maximum dry unit weight, as well as an increase of the compression index and the coefficient of vertical consolidation. Also, the contaminant causes a decrease in specific gravity, the optimum moisture content initial void ratio, the swelling index, the coefficient of permeability, and cohesion between soil particles.
Niniejsza praca została poświęcona badaniu wpływów zanieczyszczeń ściekami na właściwości geotechniczne próbek gleby gliniastej. Czynnikiem zanieczyszczającym są ścieki przemysłowe, uwalniane z rafinerii Thi-Qar jako produkty uboczne produkcji i wyrzucane bezpośrednio na glebę, powodując jej zanieczyszczenie. Ten produkt uboczny będzie dalej określany jako węglowodory ropopochodne (THP), w celu uniknięcia złożoności omawianych wpływów poszczególnych składników ścieków przemysłowych na właściwości geotechniczne gleby. Próbki gleby zostały pobrane z rafinerii Thi-Qar w mieście Al.-Nassyriah, położonym na południu Iraku, o współrzędnych geograficznych (N 305916.2, E 0461332.8). Zanieczyszczone i nierozłożone próbki gleby zostały pobrane w trzech miejscach na badanym obszarze oraz na trzech głębokościach w każdym z tych miejsc. W celu zbadania wpływu różnych stężeń węglowodorów ropopochodnych na właściwości geotechniczne gleby, przeprowadzono badanie trzech lokalizacji o bardzo zanieczyszczonym obszarze (NA1), nieznacznie zanieczyszczonym obszarze (NA2) oraz nienaruszonym obszarze (NA3).
