A filtration system, the filtration system comprising:
- a mattress formed from a top layer and a bottom layer made of a water permeable geotextile material sufficient to allow water and/or air to pass through while retaining a filtration media;
- a plurality of sides that are connected to outer edges of the top and bottom layers of the mattress, thereby defining an outer perimeter of the mattress and enclosing an interior space of the mattress, wherein the plurality of sides are made of the water permeable geotextile material;
- the plurality of sides of the mattress are formed from folded portions of the top layer that are sewn to the bottom layer and/or from folded portions of the bottom layer that are sewn to the top layer to form the mattress.
A method of remediating contaminated sediments, groundwater, and/or porewater, the method comprising:
- providing a filtration system having a mattress comprising:
- a mattress formed from a top layer and a bottom layer made of a water permeable geotextile material sufficient to allow water and/or air to pass through while retaining a filtration media;
- and
- a plurality of sides that are connected to outer edges of the top and bottom layers of the mattress, thereby defining an outer perimeter of the mattress and enclosing an interior space of the mattress, wherein the plurality of sides are made of the water permeable geotextile material and the plurality of sides of the mattress are formed from folded portions of the top layer that are sewn to the bottom layer and/or from folded portions of the bottom layer that are sewn to the top layer to form the mattress;
- placing or otherwise installing the filtration system over a contaminated area requiring remediation;
- and
- filling the interior space of each mattress with a filtration media.
