ABSTRACT OHM designed and installed an in situ bioremediation system with an above ground water treatment system at a petroleum hydrocarbon distribution and fuel facility. The remediation system consists of an infiltration trench system to deliver treated, amended ground water to the upper silty lens, and an injection well system to deliver water to the lower sand and gravel lens. A French drain is located downgradient of the groundwater injection systems to provide hydraulic control of the site. Recovered ground water is pumped to an on-site treatment system prior to re-injection.

Energy Consuming

Contaminated soil from industrial or agricultural activities poses a health threat to animals and humans and can also have a detrimental effect on economic systems by making land unsuitable for agriculture and other economic purposes. This problem is of particular concern in tropical developing countries where agriculture is the economic base. Traditional methods for soil remediation are often expensive and energy consuming. In-situ bioremediation has been proposed as a cheaper alternative to conventional methods in areas where remediation would otherwise not be implemented. Despite encouraging results in the laboratory, the practice of in-situ bioremediation is limited, partially due to its inefficiency at low temperatures. The objective of this study is to provide an inventory of some waste products that potentially can be used as amendments for in-situ bioremediation in developing countries in tropical climate. Emphasis has been given to map efficient methods that are appropriate to economically marginalised people in such countries. Waste from livestock operations, crop residues and processing waste constitute the major waste flows in many developing countries. A number of organic by-products can potentially be used to stimulate microbial activity for bioremediation purposes. Three amendments; whey, pyroligneous acid and compost teas were selected to be studied in detail due to their liquid nature and documented capacity to stimulate microorganisms with capacity to degrade pollutants. Experiments are needed to determine their potential for in-situ bioremediation in developing countries in tropical climate.

The Cost

It is shown that the mechanical remediation of oil-contaminated soil is carried out quickly and radically, and the cost of this method (from 3.8 to 62.4 million rubles/ha) is several times higher than the cost of bioremediation. Soil cleaning by in situ bioremediation can last from 1 to 3 growing seasons, but it does not require the transportation and disposal of hazardous waste and does not destroy the soil cover. Adding sorbents and ameliorants for bioremediation of oil-contaminated soils is often justified, since it significantly expands the capabilities of the method, although it increases the cost of cleaning from 1.0–4.3 to 1.1–18.3 million rubles/ha, depending on the type and dose sorbent.
