Fourth graders traveled to West Lebanon, NH to see an open landfill in full operation. They also toured the Recycling Center on site and saw how a larger scale Transfer Station operates. On our way back to Ludlow we stopped at the rest area in Hartford for a picnic lunch and enjoyed playing in the leaves after eating.
At the landfill we learned and saw many interesting things, some of which
were:
NH requires all landfills to have 2 layers of plastic lining to prevent leachate from contaminating groundwater and soil.
The day's weather has a lot to do with whether or not you can smell the landfill gases. (We smelled nothing due to a low cloud cover and mist.)
These landfill gases will soon be used to generate electricity.
Huge trash compactors with steel spiked wheels compact the trash continuously throughout the day.
At the end of each day the garbage must be covered with either 6 inches of dirt or a GIGANTIC tarp.
There are wells near the landfill that are monitored continuously for ground water contamination.
Wood ash, ground up sinks and toilets are used as layers in the landfill instead of dirt and gravel.
Areas of landfill that are not currently in use are covered with grass to keep seagulls away. Why? Seagulls DO NOT like walking on grass!
