Defending Landfills Accused of LFG Impacts on Neighboring Properties

It is well-known that LFG migration and its impacts on the environment are difficult to quantify. However, specific quantitative and semi-quantitative tools (gas fingerprinting) for evaluating offsite LFG migration and impacts have been developed. One of these tools includes “fingerprinting” LFG to compare it to the detected gaseous impacts ...
