Public crude oil fields in Wonocolo sub-district were active from 1942 until now and have inadequately operated. The aims of this research were to measure the level of total petroleum hydrocarbon (TPH) pollution and their distribution in soil and surface water at the Wonocolo public crude oil fields. Twelve composite soil samples were collected from uncontaminated and contaminated sites of old well (OW), transportation line (T), and refinery area (R) at the depths of 0–30 cm, 30–60 cm, and 60–90 cm. The composite surface water sample was obtained from two points with different distances from the river side. TPH from soil and surface water samples were extracted using soxhlet and gravimetric method. Quantification of TPH was performed using Fourier Transform Infrared (FT-IR) Spectrometer. From the results of this study, it was concluded that soils and surface water are contaminated by TPH of 119.80–107,190 µg/g and 211,025.73 µg/L, respectively. TPH is clearly located in the upper of 0–30 cm depth at OW, T, and R sites (52,328.14–107,189.63 µg/g). These concentrations exceeded the soil quality standard of TPH and classified as category A for human hazard risk. The findings from this study show that there are considerable health risks which are potentially poisonous to humans in the local area. We recommend that remediation could be conducted using biological methods to reduce TPH pollution level.

In the paper, a comparison of the efficiency of riverbank treatments is outlined for the Krajkowo well field, where different methods of water abstraction are used. The water is extracted from 29 vertical wells that are located at a distance of 60–80 m from the channel of the River Warta and from a horizontal well with radial drains located 5 m below the bottom of the river. The results of a two-year water-quality investigation indicate that the water quality in both types of abstraction system is influenced by the quality of river water. The water quality observed in the horizontal well is closely similar to that of the river water, with similar concentrations of sulphates, nitrates and micropollutants, but a reduction in bacteriological contamination and plankton is clearly seen. The reduction in contaminants is mainly the result of physical processes, such as mechanical entrapment of suspended material and colloids as well as bacteria and plankton. In the vertical wells, the influence of contamination from river water is also visible, but the reduction in contamination is more significant, especially in cases of bacteria, plankton, micropollutants and nitrates, and is determined by both physical and chemical processes, such as sorption, dissolution, red-ox processes and denitrification. The present research shows that river water treatment is more effective in the case of vertical wells. The most favourable distance of a well from the channel of the river, from the perspective of water quality, is 150–200 m, which corresponds to a residence time of about six months.

Badania stabilnych izotopów węgla znajdują zastosowanie zarówno w celach poznawczych jak i praktycznych. Służą do określenia genezy węgla w środowisku wodnym oraz są stosowane do wykazania zanieczyszczenia związkami zawierającymi węgiel. Na podstawie analizy składu izotopowego węgla w wodach podziemnych można między innymi ocenić zasięg oddziaływania składowiska odpadów na środowisko gruntowo-wodne. Celem artykułu jest przedstawienie szerokich możliwości wykorzystania oznaczeń stabilnych izotopów węgla nieorganicznego do interpretacji dotyczącej wód powierzchniowych i podziemnych pod kątem naturalnych i antropogenicznych czynników wpływających na stan ich jakości. Z przeprowadzonej analizy wynika, że metoda bazująca na pomiarach składu izotopowego węgla w środowisku wodnym może być stosowana powszechnie, ponieważ węgiel pochodzący z różnych źródeł różni się wyraźnie składem izotopowym.

Carbon isotope analyses can be used for knowledge and practical purpose. They can be used to assess the genesis of carbon in geochemical environment, and may also be used to indicate groundwater contamination by carbon-containing compounds. Based on this method it is possible to delineate contamination area by the activity of the landfill site. The aim of the paper is to indicate the possibilities of using carbon isotope composition for interpretation surface water and groundwater in terms of natural and anthropogenic factors influencing their quality. This method can be applied universally in water research, because carbon sources are different in isotopic composition.
