ABSTRACT:
Asbestos is often removed from buildings by treating the asbestos with water to prevent the asbestos fibers from becoming airborne. The water contaminated with asbestos fibers is then removed. Often the leaks by the contaminated water must then also be contained and eliminated. Aqueous-fluid absorbing polymer, in a vehicle to contain the polymer, absorbs and immobilizes the contaminated water for more efficient disposal of the asbestos.
