Solution #1: Treating Toxins

Newer landfills are being constructed with synthetic membranes to prevent mercury from escaping into soil and groundwater. Instead, the toxins are drained through a collection of pipes and discharged into a sewer system where they can be retained, incinerated or converted into fertilizer.

How do you manage landfill sites?

Organize around the waste management hierarchy in decreasing preference: Reduce, Reuse, Recycle, Compost, Energy Recovery, and Landfill. Begin with waste reduction and reuse programs because that’s where you’ll find the most leverage per dollar invested, followed by recycling and refuse collection.

Why are landfills overflowing?

All over the country, subterranean garbage heaps called landfills are rising, fueled by the 292.4 million tons of municipal solid waste (MSW) the US produces each year. According to the EPA, in 2018, almost half of that trash (49.997%) went to landfills around the country.

How can we protect groundwater from landfills?

Fortunately, modern landfills have many safeguards to protect groundwater. New landfills are required to have clay and synthetic liners as well as leachate collection systems. (Leachate is liquid from a landfill containing contaminants.)

How do landfills prevent groundwater contamination?

Modern sanitary landfills are constructed to prevent leachate contamination of groundwater or surface waters. The bottom of the landfill is lined with impermeable layers, and the leachate is collected and treated before being released to the environment.

How do you remove leachate from the landfill?

There are many methods of leachate treatment [5] such as: Aerobic Biological Treatment such as aerated lagoons and activated sludge. Anaerobic Biological Treatment such as anaerobic lagoons, reactors. Physiochemical treatement such as air stripping, pH adjustment, chemical precipitation, oxidation, and reduction.

What problems do landfills cause?

The three main problems with landfill are toxins, leachate and greenhouse gases. Organic waste produces bacteria which break the rubbish down. The decaying rubbish produces weak acidic chemicals which combine with liquids in the waste to form leachate and landfill gas.

Why is compaction done at landfills?

A landfill compaction vehicle has two main functions: to spread the waste evenly in layers over the landfill, and to compact waste to reduce its volume and help stabilize the landfill.
