28 Claims

1. A method for adsorbing toxic materials, the method comprising:

exposing a fluid to a filter for a first minimum duration, wherein the fluid comprises water and a toxic material comprising at least one of a dioxin, a furan, a polychlorinated biphenyl (PCB), or an ethylhexylphthalate, and wherein the filter comprises a needlepunch mat consisting of basalt fibers and having a thickness selected from about 6.5 mm, about 13 mm, or about 20 mm; and

enabling at least a portion of the toxic material to be adsorbed by the basalt fibers.
