where human health and natural resources are
affected
 Reintegration of remediated contaminated sites into
the economic cycle
 Contribution to urban renovation and improvement
of living conditions in inner cities

Goals and strategies of the PNRSC
Goal 1: “Management of contaminated sites”
Improvement of the management of contaminated sites
through risk assessment and improved administrative
procedures
Goal 2: “Development

Lessons Learned
•
Communication with the Community
•
•
•
•
Federal investment in remediation projects pays off
•
•
•
•
Community and resident participation is an important part of the decision making process in
order to achieve acceptation of remediation solutions.
In two pilot projects experiences were gained with risk communication, however the
communication process is still not regulated in Mexico.
Open communication channels increase project success.
success
Federal and state governments have financed mayor projects with aprox.
aprox 90 Mio USD
USD, which
have created economic impulses around remediated sites.
The benefits gained from improved living conditions for the population in mayor cities
outweigh the remediation costs.

Good regulation instruments have helped to create awareness and responsibility among
polluters.
International cooperation (with GIZ, Germany and RELASC) has been very successful to
achieve specific knowledge and access to state of the art technologies
