If necessary, nutrients or hydrogen peroxide or both can be added at a later date, pending laboratory analysis of soil samples obtained from the site. Both of the treatments mentioned provide onsite treatment in which the entire bio-remediation process can be completed without any excavation or soil removal. This form of remediation has significant environmental and economic advantages when compared to other means of remediation. C. Hazardous Waste Lagoon Bio-remediation Hazardous waste lagoons can be treated by merely spraying the product and the proper nutrients on the surface of the lagoon. Circulating and aerating the lagoon with the use of a direct drive mixer will greatly increase the rate of biological degradation.
Eliminator loosens the extensive oil and grease built up on the ties, ballast and rock.
The pretreatment is then followed by a high pressure wash, which removes the oil and grease from the ties and ballast and deposits this material on the soil below. The ballast and soil is further inoculated with PDM-7 HC and proper nutrients. These petrophilic bacteria will digest the hydrocarbons which were previously deposited on the soil below the ballast. This discussion is presented as a general outline for the process for soil bio- remediation. Each potential clean-up is site specific and should be treated as such.
