An apparatus for in-situ remediation of contaminated soil or sludge having a trenching tool and an injection system for applying remediation agent to the contaminated material during in situ communication. The remediation agent is injected into the contaminated material by the injection system preferably having a plurality of injection nozzles positioned along the length of the trenching tool. The treated material is backfilled or deposited directly into the trench excavated by trenching tool thereby obviating the need for off-site disposal. The constituent remediation agents in the remediation agent may be adjusted to adapt to varying site conditions and contaminants. The remediation agent may also be heated to accomplish volatile stripping of the contaminated material or to activate microbial agents in a low temperature environment.
