In carrying out this project, various salient activities were outlined for a complete elimination of the Oil contaminants from the receiving soil.

These include:

1.1.Personnel & equipment mobilizationPersonnel & equipment mobilization

2.2.Baseline status study (pre study)Baseline status study (pre study)

3.3.Selection & provision of appropriate nutrientSelection & provision of appropriate nutrient

4.4.Provision & planting of habitat plantsProvision & planting of habitat plants

5.5.Baseline confirmation study (post study)Baseline confirmation study (post study)

Four major activities were coined out from the five mentioned points above

Bioremediation can be defined as a process of utilizing biological agents, (such as micro-organisms and plants) to get rid of pollutants or contaminants.

Bioremediation can be broadly subdivided into five approaches:

MAJORPARAMETERS

Hint!

Summary …it is generally observed that the bioremediation

exercise is alleviating the extent of pollution at the impacted location.

A further check on the stability trend in the parameters, shows that the location will at the endof about 42 days gain its original status. This isin-line with the ‘Bioremediation Efficiency Check’, (BEC) done on the generated data.

THANK YOU THANK YOU VERY MUCH FOR VERY MUCH FOR
