Target organic substance can be contained, filtered, absorbed and/or used to shut down flow, and water drained off, with a system having a first, fluid-permeable, hollow housing member; a second, fluid-permeable, hollow housing member disposed inside the first member; and, disposed between the first and second members, a fluid-filtering/absorbing material. A fluid can pass through the first and second members and the fluid-filtering/ absorbing material, and have the target organic substance, which may be found with the fluid, filtered and/ or absorbed by the fluid-filtering/ absorbing material.
