Claim:
1. A system for controlled verified remediation of contaminated spoil, comprising: a supply of sorbent capable of adsorbing contaminants; a supply of water; a remediation pathway conveying spoil from an intake point to an output point; a sorbent analyzer adapted to analyze characteristics and conditions of said supply of sorbent before use and to determine remediating potency of any specific supply of sorbent before adding the sorbent to the contaminated spoil; a pre-analyzer at said intake point adapted to analyze characteristics and conditions of contaminated spoil entering said remediation pathway; a water adder in said remediation pathway after said pre-analyzer, adapted to add water when necessary to increase moisture content of the contaminated spoil; a sorbent adder in said remediation pathway after said water adder, adapted to add a proper determined quantity of sorbent to said contaminated spoil; a post-analyzer at said output point adapted to analyze characteristics and conditions of remediated aggregate exiting said remediation pathway; a controller receiving data from and controlling operation of said sorbent analyzer, pre-analyzer, water adder, sorbent adder, and post-analyzer; and a set of remediation verification data derived and recorded by said controller; where said controller determines whether and how much water should be added by said water adder, and how much sorbent should be added by said sorbent adder, in accord with characteristics and conditions of said supply of sorbent and the contaminated spoil as analyzed by said sorbent analyzer and said pre-analyzer; where said controller verifies remediation of the contaminated spoil into aggregate in accord with characteristics and conditions of the remediated aggregate as analyzed by said post-analyzer; and where said controller derives, records, and reports said remediation verification data.
