Geosyntec Consultants<br />

components that function together with natural conditions and buffers. Combined, these<br />

engineered and natural components provide overlapping environmental safeguards throughout<br />

the operating and post closure life of the landfill.<br />

<strong>Management</strong> System<br />

Modern managed landfills are designed and operated to prevent human or vector (e.g., insects,<br />

rodents, birds, etc.) contact with disposed waste. Additionally, modern landfill designs use<br />

engineered liners of low permeability to contain waste, leachate, and landfill gas and protect<br />

groundwater.<br />
