| 1. An apparatus for delivery of a remediation composition into a waste stream comprising:
a reservoir for a liquid, said reservoir comprising one or more openings;
a dispensing element comprising a hollow cylindrical tubular body defining an interior cavity with a volume wherein the cylindrical
tubular body comprises;
one or two open ends; and
a wall with an inner surface and an outer surface wherein at least a portion of the wall is porous and has a pore size and
total pore volume that renders the wall pervious to a liquid-borne composition while impervious to solid retents;
said dispensing element being positioned such that the porous portion of the wall is disposed within the reservoir while the
dispensing element is fixedly disposed within at least one of said one or more openings in the reservoir such that a liquid-borne
composition from within the reservoir can pass through the porous portion of the wall to the outside of the reservoir; and
wherein the apparatus can be oriented such that a liquid-borne composition from within the reservoir can be dispensed by gravity
into a waste stream over time.
