1. A capping layer delivery system comprising:
(a) blending and delivery apparatus comprising:
i. a housing;
ii. a first input port configured to receive an organic adsorption ingredient for delivery inside the housing;
iii. a second input port configured to receive an organic polymer delivery ingredient for delivery inside the housing;
iv. an intake chute configured to receive a non-organic silica carrier ingredient for delivery inside the housing;
v. an auger driveshaft located inside the housing;
vi. an auger coupled to the auger driveshaft and located inside the housing;
vii. a motor coupled to the auger driveshaft; and
viii. a discharge opening located on the housing;
wherein the motor, when energized, is configured to rotate the auger driveshaft, which rotates the auger inside the housing (53) to blend the organic adsorption ingredient received via the first input port, the organic polymer delivery ingredient received via the second input port, and the non-organic silica carrier ingredient received via the intake chute to form a capping composition layer mixture output via the discharge opening;
(b) an output hopper receiving the capping composition layer mixture output from the discharge opening;
(c) a conveyor belt receiving the capping composition layer mixture output from the output hopper; and
(d) a spreading means receiving the capping composition layer mixture on the conveyor belt and distributing the capping composition layer mixture throughout a distribution pool and forming a capping composition layer in an area in need of remediation.
