Are there extra precautions that need to be taken when digging or building around an old landfill site?
Yes, municipal landfills built prior to modern construction practices often were not built to properly vent landfill gas that builds up when the buried waste breaks down. This lack of proper venting can cause landfill gas (methane) to build up and travel the path of least resistance to migrate through the soil. This can lead to potential explosive conditions. When excavating soils for building near an old landfill there is a potential for methane gas to migrate to the disturbed soils. Please contact your local Tri-County Environmental Health office or your local zoning department to determine if there are precautions to be taken in a particular area.
