The industrial revolution and former waste-management practices have left behind a large number of sites whose ground may be polluted. Over recent years, French policy for spatial planning has promoted the rebuilding of cities upon cities (ALUR Act) by encouraging the reuse of industrial wasteland in order to limit urban expansion in natural or agricultural areas.

This situation often leads to new, previously forgotten or unknown polluted areas being discovered during development projects or works involving the digging and extraction of earth.

Some of the pollution that is discovered by chance during construction work can end up being poorly managed and/or ignored.

We have just put produced a guidebook to help manage and prevent risks in these situations.
