Passive Remediation Systems Ltd. (PRSI) was founded in 2004, by David Derbowka, in response to the leachate pollution problem that many landfills create. After successfully proving a number of projects, PRSI now provides services globally, and is widely recognized as a leader in phytoremediation.


Today PRSI is a complete environmental company, providing turnkey environmentally sound remediation solutions, that result in the recapture of property value, and new revenue streams from the previously polluted property.
