Socio Economic Impact

The increasing need for fuel derived from petroleum is also in line with the increased exploration and production activities of petroleum. Besides producing crude oil products, this activity also produces petroleum waste. This waste will pollute the soil which will have an impact on environmental damage, disruption of human health and other living things. Therefore according to Veegha (2008), an efficient and environmentally friendly method for treating petroleum waste is needed. One of the waste treatment methods is using phytoremediation method. Phytoremediation is defined as a technology for cleaning, removing or reducing harmful pollutants, such as heavy metals, pesticides, and toxic organic compounds in soil or water using the help of plants. This research was conducted for three months from September to November 2019 at the open nursery of PT. CPI with paranet shade 60%. This study aims to determine the effectiveness of bahia grass (P. notatum) in degrading Total Petroleum Hydrocarbon (TPH) in petroleum-contaminated soils in the Rokan Block PT. Chevron Pacific Indonesia and analyze the socio-economic impact of phytoremediation on local communities. The results showed that the effectiveness of Bahia (P. notatum) grass proved effective in reducing the concentration of Total Petroleum Hydrocarbon (TPH) in petroleum-contaminated soils in the Rokan Block operating area of PT. Chevron Pacific Indonesia. The percentage of effectiveness shows a decrease in value of up to 58.38%. The socio-economic impact of phytoremediation on local communities has a positive impact with the planned phytoremediation activities using bahia grass with the community as work agents for planting the grass.

This study investigated the potential of Aspergillus sydowii and Fusarium lichenicola as mixed cultures in the biodegradation of Total Petroleum Hydrocarbons TPHs in oilfield wastewater. Oilfield wastewater was collected from an onshore oil producing platform and biodegradation of total petroleum hydrocarbons was investigated using standard methods. Fungi were isolated from oilfield wastewater contaminated soils obtained from the vicinity of the oil producing platform. Experimental control set-up and treatment with mixed culture of fungal isolates were periodically analyzed on days 7 and 21 intervals for total petroleum hydrocarbon degradation using Gas Chromatography (GC). The total amount of TPHs on day 1 recorded 381. 871 mg/l.  The amount of TPHs on days 7 and 21 in the mixed culture of fungi was 108.975 mg/l and 21.105 mg/l respectively while TPHs in control was 342.891 mg/l and 240.749 mg/l respectively. There was a significant difference between the mixed culture and the control on days 7 and 21 at p≤0.05. The results therefore revealed actual and significant reduction of TPHs in the mixed culture. In addition, there was clearance of n-alkanes by the mixed culture. This suggests that fungi have great potentials in biodegradation of TPHs and in remediation of TPH contaminated environments.

Phytoremediation of hydrocarbon-contaminated soils is a challenging process. In an effort to enhance phytoremediation, soil was artificially contaminated with known concentration of light crude oil containing Total petroleum hydrocarbon (TPH) at a concentration of 75 gkg−1 soil. The contaminated soil was subjected to phytoremediation trial using four plant species (Oryza longistaminata, Sorghum arundinaceum, Tithonia diversifolia, and Hyparrhenia rufa) plus no plant used as control for natural attenuation. These phytoremediators were amended with concentrations (0, 5 and 10 gkg−1 soil) of organic manure (cow dung). Results at 120 days after planting, showed that application of manure at concentrations of 5 and 10 gkg−1 soil combined with an efficient phytoremediator can significantly enhance reduction of TPH compared to natural attenuation or use of either manure or a phytoremediator alone (p<0.05). The study also showed that a treatment combination of manure 5 gkg−1 soil, with a phytoremediator gives a similar mean percentage reduction of TPH as manure 10 gkg−1 soil (p>0.05). Therefore, the study concludes that use of phytoremediators and manure 5 gkg−1 soil could promote the restoration of TPH contaminated-soils in the Sudd region of South Sudan.

Biodegradation of hydrocarbons by microorganisms represents one of the primary mechanisms by which petroleum and other hydrogen pollutants are eliminated from the environment. This work was carried out on the effect of microorganisms on the biotreatment of oil in crude oil contaminated soil. Microorganisms were isolated from two experimental soil samples contaminated with Bonny Crude and normal uncontaminated soil as a control over a period of seven months. The microbial as well as the physico-chemical parameters of the soil samples were all analyzed using standard methods. Changes in total petroleum hydrocarbon level were measured appropriately. Treatments used were the microbial isolates. Forty-four microorganisms were isolated from the contaminated soils and identified as species of Pseudomonas (7), Flavobacterium (6), Bacillus (8), Proteus (4), Klebsiella (1), Pencillium (5), Aspergillus (7), Fusarium (3), Trichypton (2) and Neurospora (1). Ten of the forty-four isolates had ability to degrade crude oil in the laboratory. On contamination a value of 1.0X105 cfu/g in microbial counts were obtained followed by a subsequent increase in population levels after a period of 2months with a value of 1.0X106 cfu/g. Oil application to the soil resulted in an increase in total petroleum hydrocarbon from 0.31 ppm to 5.53 ppm; organic matter from 0.41% to 7.34%; available phosphorus from 1.75 ppm to 2.84 ppm. The treatment measures all showed progressive decrease in oil concentration in the soil. Mixture of bacterial and fungal isolates as a treatment measure proved to be more favourable above all others, it brought the concentration from 5.53 ppm to 0.31 ppm after a period of 5 weeks of treatment, which is same value with the normal soil (uncontaminated). Species of Pseudomonas, Bacillus, Flavobacterium, Proteus, Klebsiella, Penicillium, Aspergillus, Fusarium, Trichyphyton and Neurospora had potential for the degradation of bonny crude oil. They could therefore be employed in environmental cleanup of petroleum spill site.
