REMEDIATION OF CONTAMINATED MARSH LAND:
Introduction:
Coastal wetlands are commonly known as marshes or marsh land. There are various kinds of marsh land from coastal to inland and saltwater to fresh water etc but mainly distinguished as Tidal marsh lands, Freshwater marsh lands, Mangrove swamps or brackish wetland (Mitsch and Gosselink, 2000). Wetland ecosystems are herbaceous vegetations that not only protect wide variety of wildlife but also protect the shores support coastal fisheries also (US EPA, 2004).
Due to the increase in pollution contamination of marshes are increasing rapidly. Case studies suggest, the principal cause of pollution is anthropogenic activities rather than the accidental oil spills in the marine ecosystem contrary to belief of the people. Cooney (1984) studied that fresh water marshes are deliberately polluted by human activities.
Another major cause of pollution is deposition of heavy metals, trace metals which is very harmful due to its high toxicity, persistence and bioaccumulation in nature (Tam and Wong, 2000). These pollutions are mainly caused by mining and processing of ores and metals from the industries.
There are many methods to treat a remediation site: 1) Physical 2) Chemical 3) Biological. Studies suggest that majority of contaminants are removed by Physical and Chemical Methods then biological Method is employed. Complete biological approach is yet to be used for maximum removal of the contaminants.
Aim and Objective Of the study:
To study the different contaminants present in the marsh lands and studying what are the major pollutants present in the sites.
To study the pre assessment test that is the conditions and factors that affect the bioremediation e.g. pH , temperature, extent of ...

...osporium, Penicillium Rhodotorula, Sporobolomyces, Trichoderma.
Plants that help in bioremediation are rhizophores, mangroves, lemnia, Spartina etc.
METHODOLOGY:
1) Sampling of the soil and Field study – Type of area to be treated and bio monitoring of the field to decide whether bioremediation is possible mainly by pre-treatment assessment.
2) Pre treatment assessment - factors that affect the bioremediation e.g. pH , temperature, extent of damage done to the marsh land, type of soil and what kind of microorganisms present and type of vegetation present
3) Design of the best approachable bioremediation method
4) Finding out the microorganism or plants that degrade the maximum percentage of contaminant.
5) Applying it in the field conditions and studying its effect in the change in soil or whether it is changing the soil conditions or ecological environment.
