Dear Patrick Brehery,

To assess air pollution by decomposition products (gaseous) you can use the express method (aspirators with indicator tubes). About 20 years ago there was also a system for determining gases by express method (aspirators with indicator tubes and a probe) directly in the ground (if I'm not mistaken, at a depth up to 2 meters).
To assess the risk of contamination of groundwater and surface water, you can join to group at Linkedin "Landfill Groundwater Monitoring" (www.linkedin.com).To assess air pollution by decomposition products (gaseous) you can use the express method (aspirators with indicator tubes).
