Hydrocarbons at the Vojvoda Stepa oil drilling sites

Abstract

The objective of this study was to assess the effect of oil drilling waste on the environment. This paper reviews the results of analyses of sotl and ground water taken from the two oil-drilling sites situated near the Vojvoda Stepa village tn eastern part of Banat region. A total of 29 soil samples and 5 surface and ground water samples have been analyzed. In the location of Vojvoda Stepa | (VS1) and Vojvoda Stepa 2 (VS2) total petroleum hydrocarbons (TPH) ranged from 1, 54 g/kg to 5, 98 g/kg and 6, 26 g/kg to SS, 94 g/ke respectively. The soils in the location VS2 should be adequately recultivated in order tt lower the TPH to the aceptable level of 2. 5 ofke. TPH concentrations in water ranged from 6,8 mg/d? to 44, 3 myfdm. The methoc detection limit for water was 5 mg/dnv. US standards for ground water specify that the water more than 100 m away from a possible source of potable walter may Contain it} to 50 mgldne af TPH, while the water potentially usable for water supply should no have more than | mg/dm’ of TPH (CERL Special Report, 2000). If we apply this stan dard, there is no risk for water supply since there are no settlements near the analyzec sites.
