A non-woven fabric cylinder adapted for insertion within a canister of screened casing pipe that is placed in underground monitor wells to collect and contain spilled or leaked hydrocarbons such as gasoline or diesel by absorbing same upon contact. The absorbed substance is solidified within the cylinder as a rubber-like mass. The consolidated mass is contained within the screened canister, will float indefinitely and is easily retrieved and handled for disposal. The cylinder will not leech solidified hydrocarbons when exposed to pressure limits used to determine landfill suitability.
