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.
